That Pedal Show - Introduction To Auto Wah & Envelope Filters

[@FostersLab]

You know you're on a TPS video when an "Introduction" on something as specific as envelope filters lasts a WHOLE HOUR. No other channel reaches that level of perfection :) Cheers from France, as always :)

[@deltaflows147]

Foster's Lab salut:D

[@FostersLab]

Delta Flows Salut :p

[@DoobTube71]

My favorite pedal effect,...the envelope filter! Thank you Jerry Garcia. Thank you TPS!!!

[@777Yoni]

The show I was waiting for... My inner Jerry is in a happy place.

[@bobmeyrick8264]

The Spatial Delivery "Sample & Hold" mode re-creates the Oberheim VCF sound which can be heard to great effect on Frank Zappa's "Ship Ahoy", and FZ's solo on "Inca Roads" is maybe the definitive use of an envelope filter. The full Inca Roads solo is from the live album "You Can't Do That On Stage Anymore Volume 2 - the Helsinki Concert" - an edited version appeared on the studio album "One Size Fits All".

[@travisjames8087]

THIS IS WHY I NEED YOU GUYS. I'm completely tone illiterate but today I learned that an auto-wah is an envelope filter. keep on with the lessons

[@frmcf]

Here was me thinking Auto-wah was the capital of Cana-dah... thanks for clearing that up, guys! Now I'm gonna dig out my Boss FT-2 and play the intro to Carrot Rope.

[@ThatPedalShow]

+Fraser McFadyen agahahahahah!!!!

[@rasm0225]

Harness your hopes, Fraser

[@MarkHammer52]

I actually live in Ottawa. And believe it or not, there is an automotive upholstery and glass repair place called "Auto-Wa". I smiled a big smile the first time I drove past and saw the sign.

[@scramblesthedeathdealer]

I still need a Boss FT-2 for my collection.

[@nicklovering2749]

Perfect timing! Just got the ability to watch KZbin through my TV. Work from home most Fridays and had geared things up to have my lunch watching this. Great start to the weekend 👍

[@gibbysg8143]

Proud fuzz factory owner here! Such an incredible/whacky pedal that’s so much fun to tinker with and find new sounds

[@discipleofec]

In my opinion "3 Leaf Audio" is the best envelope filter recently.

[@forrestmark805]

The Grateful Dead is undoubtably an American thing but Jerry Garcia and Bob weir were the master of envelope filters

[@huckreason8455]

Yessir

[@zeppelinboys]

Grateful Dead were the greatest American band! toured for 30 years non stop. wrote hundreds of timeless songs with themes of life, love, everything about the human experience. they are the ultimate melting pot of American genres in one group. Grateful Deads recordings should all be in the Library of Congress. The Jerry Garcia Band shows too. then Jerry died that was the real end of the 60s and true 'Freedom' in the United States. now everyone is living the life of surfs, except our overlords are companies and banking conglomerates.

[@albaxter8711]

[@morphine0000]

Truly sirs, there is something new to be learned at That Pedal Show every week. For example, what "bucket of chips" is. I feel more educated by the second.

[@garystackhouse5787]

I'm about as big a fan of envelope filters as you guys are of the Boss Metal Zone... but I STILL had to watch the whole hour! THAT is how good this show is.

[@ThatPedalShow]

+Gary Stackhouse Hahaha! Nice one Gary. I wasn’t a huge fan either (Mick here) but it’s funny how challenges like these send you off in new directions. A nice break from the routine. Thanks for watching!

[@777shea1]

I know this vid is several years old, but thank you for doing this. There's a HUGE lack of AW & EF vids, particularly educational ones. I'm building my first board & am trying to figure out which of the 2 (aw or ef) I wanna go with. Those MuTrons sound so good, too bad they're so pricey.

[@briancherry8088]

I love using the Qtron on my bass, but like you mentioned, either the lows are really low or the highs are really high, but you cant move around the neck without losing something. So, I use an overdrive pedal with the gain off for a clean boost.

[@AlbertoMartinezDelRio]

With te Qtron+ the Boost knob in Normal mode passes input signal through the filter at its original level. Boost mode increases the signal gain to the filter according to the Gain control setting.

[@bretonleo8740]

Meatball + fuzz at 20 minutes is just amazing ! Thanks guys and cheers from bask country!

[@ThatPedalShow]

+Breton Léo Meatball is killer!!

[@yannthree]

Their banter is like slowly tumbling down the stairs and hitting every stair on the way down, without ever hitting the bottom - that said - like the pedal demos

[@ThatPedalShow]

Welcome to That Pedal Show!

[@jhnlk]

"That's what wah wah." - Mick Taylor everybody. Literally speaking through the guitar.

[@hellotheresteve]

The Mr.Black Fwonkbeta would've been a great addition to this round up. Dan & Mick, if you ever get the chance to check it out I highly recommend!

[@GregF71]

definitely!!! i got one and it's sick either on guitar or bass :)))

[@SporkMartial]

Every time I hear the spatial delivery doing its thing I just want one even more

[@mgbasinski]

Ah, that step mode from the Spatial Delivery! One of my favorite Zappa guitar solos is an extended step-mode env filter jam ("Ship Ahoy", I first heard that on the "Shut up and play yer guitar" collection). Brilliant effect!

[@jordandangelo180]

Mark Basinski Can’t Believe you mentioned Ship Ahoy!!!! One of all my time favorites since I discovered back when I was 19 yrs old ( now 35 ) I was blown away upon first hearing it. At the time I had no clue how he got that sound. I figured it was some sort of fixed wah pedal through a filter. I have to watch the section of the video where they use the extended step feature on the EQD Spatial Delivery. Awesome comment! I also know FZ used the Roland Space Echo as well as the Son of Kong EQ & Boost and the ever so awesome and gnarly Dan Armstrong Green Ringer. If you have any other knowledge on Frank’s effects I would love to hear about it! Thanks!

[@mgbasinski]

@@jordandangelo180 Cool! Glad to know there is somebody else out there that digs that amazing solo. There are some You Tube videos out there of Dweezil Zappa talking about his effects rig and also about Frank's, and I apologize, I do'n't recall exactly how to find it, but there was one where Dweezil did talk specifically about the envelope filter gear Frank used for Ship Ahoy (if I recall correctly, back then, it was a bunch of rack mount units)

[@groovepooper]

Yes! Get Paul and Rob on the show! Just saw Jamiroquai last week and it was awesome! Was thinking how awesome it would be to have Paul on the show, dispite being a bass player. And we know you know Rob Harris! Bring it! Share the love!

[@jayfoster]

They tend to work better on the bridge pickup. More responsive. Also, no mention of Jerry Garcia? The envelope filter was a signature part of his sound ;D

[@ThatPedalShow]

+Jay Foster Guitar So we’re told. The Dead and Jerry totally passed us by. Sorry!

[@jayfoster]

No worries :D The Dead is not everyone's cup-o-tea, haha. Thank you so much for all of your hard work and generosity.

[@AWilliams7878]

Jerry is the reason I love envelope filters. A nice Estimated from '77, say the Pembroke show...just chewy chewy Mutron. Toss an octave divider after it and you're set.

[@ionobelisk]

AWilliams7878 jerryg... Master of the mu-tron

[@whiskersb5296]

Jay Foster Guitar I was going to say something similar. Despite the classic Europe '72 (pre Jerry use of the mutron iii) I think Jerry just isn't much of a presence on the other side of the pond. But he certainly is the greatest envelope filter user who used it outside of a funk context.

[@musicmann1967]

Envelope filters and/or auto wahs are so not something I could ever see me using, yet I watched this whole damn video! (the step filter was pretty cool though) I'm addicted to this show!

[@ThatPedalShow]

+Larry Lachmann Cheers Larry! I was the same (Mick here) but I’m eyeing up the new Analogman with worrying seriousness... Thanks as ever for watching.

[@PatFlanigan]

Just for fun, you guys should do a show about multi-effect pedals, including great rare ones such as the Digitech Space Station (the whole XP series really), as well as stuff that's more infamous like the Boss GT-3 etc.

[@RabbaDooDabba]

aww man.... it really is time for a reissue of the space station

[@ericcarpenter3263]

Damn. So Mick went from “never used it” to my inspiration to go buy one. Dan really broke it down so it made sense but Mick made me think it would an effect that could fit in with the band in some way. Cheers.

[@radio-friendlyunitshifter4670]

Seems the Gravitas can't handle gravity haha

[@davidkieltyka9]

Great stuff as always! I have one of Mike Beigel’s Tru-Trons as well as an original Mu-Tron III. The Tru is very close sonically to the Mu, in the same way as the Hartman flanger is close to the original Electric Mistress. About 95% there, minus some quirks baked into the particular components available when the originals were made. The Tru lets you split the gain into two parts, letting you drive the preamp into breakup without smashing the filter stage too hard (though you can do that too if you want!). It’s good stuff.

[@DavidDyte1969]

Also worth a mention: the Z-Vex Seek Wah. All analog with a ridiculous level of control over the envelope.

[@jessevassallo]

Idea pitch. How about doing some episodes where you choose a classic pedal pairing (fuzz and octaver, overdrive/distortion and delay) and have a couple of pedal combinations to get tonal comparisons. I for one would like to know which octaver pairs well with a big muff style fuzz. Keep on the awesome work guys! Cheers!

[@overdrivemejimmy6847]

Btw can we get a Christmas compilation with the best moments of 2017 and with bloopers (don't be afraid to make really long)

[@grizant]

If making an hour-long intro the envelope filter is any indicator, making videos that are too long doesn't seem to be something they're losing much sleep over...

[@mattgilbert7347]

That's a great idea.

[@mrfacephone]

I 18th this idea!

[@Bluesbuntu]

The: "Can you set the Mu Tron to your perfect Mu Tron sound?" - "Done" must be in it

[@griiseknoen]

[@edadpops1709]

Yea a Christmas blooper show with you guys would be Season cheer for sure.

[@camp689]

Long time viewer just wanting to say thanks for all the inspiration! Not only do I get serious guitar/pedal/amp envy from watching you guys, but you make me want to keep improving my playing so I can do the gear justice! All the best!

One of those episodes where I look at the title & think...not really my kind of effects. Then I watch it, find it really interesting & learn loads. Love it. Cheers guys.

[@ThatPedalShow]

+stevieboy444 That’s great to hear Steve - I was the same (Mick here.) Thanks for watching! :0)

[@BrianBowes]

Question for the show; what is the best way to approach using an Envelope Filter (MuTron III) in a wet/dry set up? Is there a way to blend in clean tone with the Envelope Filter? Love your show. Thank you so much for all you’re doing.

[@bigupbebop4706]

Just watched this after unboxing a Sonic Blue/Rosewood neck Baja Telecaster which obviously I've renamed my D&M Telecaster (Fender custom shop might be missing a trick here). Thanks for the inspiration guys. I swear when I got it out of the case Swindon and Nashville became as one for a few seconds! Another great show. I love these more experimental pedals.

[@DevilMayAsian]

Dammit! I came here to learn! Not to impulse buy the Spatial Delivery!

[@ThatPedalShow]

[@YanivZukerman]

We've all been there...

[@burninglcd]

[@DevilMayAsian]

Christian Klehm I immediately found one on eBay for about $115 used. Nearly bought it, but I had to go back to work and.....I mellowed out a bit and didn't follow through with thw purchase. Good thing, since I did some major damage for black Friday (two 4k tv's).

[@DevilMayAsian]

But its absolutely on my wish list. This and several other pedals.

[@phatman1478]

Where's the Fuzz episode with Analogman?

[@ThatPedalShow]

[@luckylicks3497]

Waited one whole week - six and a half days - for Analogman Part II. Recuperation process for now.

[@ThatPedalShow]

+LuckyLicks Hahaha!!! Nope, was never going to be two weeks in a row. Plus, it isn’t edited yet. :0)

[@WhatsUpWhitey]

I had the same thought... Where’s the FUZZ!!! Looking forward to it guys. Thanks for all you do Dan and Mick!

[@mcentee2]

AAAAAAAAAAAAAAAAAAARRRRRRRRRRRRGGGGGGGGGGGGGGHHHHHHHHHHHHHH.NNNNNNNNNNNNNNNNNNNOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO How can you do this to your loyal base Weekend ruined. (LoL - I take it this will be a Christmas treat!)

[@MrTDembinski]

Great episode. Many thanks gents. Special Delivery looks about right for my board

[@tcarad2]

I like to run my Wah (Wilson effects) into my envelope filter (3Leaf Audio Proton), which gets as close to a talkbox as a pedal can get. I also chase my EF with a compressor (Keeley Comp Pro) which really helps level the volume swing thru the sweep.

[@petergeoghegan2013]

Pick attack. What happens if you use an E-bow instead? Fun episode. Dismissed them in the past as lazy-wah. I was wrong!

[@peterjessop1878]

"That Pedal Show" the only guitar based channel you'll find that plays the Trumpton theme. Rock on. ;-)

[@zeppelinboys]

getting an OG Mu-trron would make me sooo happy! already have the silverface findertwin from '73, a nice gibson SG faded, a Slo reverb pedal, i need a mu-tron to take it to the next level lol.

[@tlb2732]

I use the Keeley Neutrino. It has an input GAIN knob to dial in the desired sensativity and a detented output LEVEL adjustment on the side.

[@ADDYNFCHD]

“Bucket o’ chips” killed me😂

[@andymellor9056]

Don't even POINT at that Mu-tron! Thanks for another great exposition guys. You are the professors of pedals.

[@ThatPedalShow]

+Andy Mellor you’re very welcome :)

[@jessievasser6293]

Up and Down are in reference to the movement you would make with a standard wah pedal to get that sound.

[@ThatPedalShow]

+Jessie Vasser Oh, now there speaks somebody smart!

[@Dudemeister]

I'm such a nerd for this show that I noticed that they replaced the Mutron with a Deluxe Memory Man on the wall.

[@vintagelife6879]

in the qtron plus thing, you can turn on the boost and use the gain like a level, , but its extremely affected by its chain placement, to work great needs to be fitst, saddly...

[@DevilMayAsian]

The DOD FX25B is my favorite EF pedal! Even when it broke, I had it repaired. The new 440 model wasnt doing it for me.

[@thomasbarrasso6099]

Great show as always. One thing: You missed Jerry Garcia of the Grateful Dead. The MuTron was a key component of his sound. Check out China Cat Sunflower, and Shakedown Street, to name a couple of songs. The MuTron needs a strong signal, which prompted Garcia to invent the on-board effects loop for installation into his guitars. I have an Alembic with that same type of system. One throw of a switch and the guitar signal goes straight to the amp bypassing all the effects. When engaged a full strength signal hits the effects. However the volume knob on the guitar only controls the level hitting the amp and does nothing to the signal hitting the effects. This makes using an envelope filter very consistent. I started with a Boss Auto-Wah, then MuTron, then Q-Tron, then 3Leaf Audio, now a the new Mu-FX Micro-Tron III. The 3Leaf is an excellent pedal that tracks very well. The new Mu-FX nails the Garcia sound, is much smaller than the original, and uses a 9V power supply. Saving up for a G2. Hopefully Christmas. Your virtual battery has made a HUGE difference in my Fulltone Germanium 69 Fuzz from the 90s.

[@TheMRCHEEFY]

Another great video chaps, I'd like to mention the Line 6 Otto Filter, great sounding pedal and cheap as chips! Also, the ZCAT step filter does what the EQD sample and hold mode does :)

[@jdavis.fw303]

Seems like you could use a EQ of some kind to tweak the annoying frequencies out of the OCD > MU to get the best of that sound without the gross intensity of certain frequencies. Or even another overdrive to get the best of both sounds.

[@RobFlaxMusic]

7:04 "huh?" I fell over... Funny one this week guys!

[@TraneFrancks]

Fun video, gents. One of the effects I got during my stint as a bassist in several bands was a Russian, blue case, EHX Bass Balls. If you've never tried one on guitar, absolutely give it a go. Great fun and the built-in distortion circuit can impart some truly gnarly tones.

[@flynn_22]

Nice would luv to get my hands on the spatial delivery

[@marcsullivan7987]

I’ve been using a DOD FX-25 on my board for years. Huge variations of effect with different guitars. Works great w my tele, not as well with my Strat, and my new tele w P90 I can’t get the sweet spot no matter how I fiddle with (the two) controls

[@wilconwel]

John Mayer uses a POG>QTron+ and it's incredible.

[@AntwhaleNearfar]

Nothing he’s ever done has been incredible other than being an incredible douchebag.

[@victor2510]

I was so confident that Mick would play the intro of "I don't trust myself"

[@justingarcia7722]

My favorite is the old 80s Japanese Ibanez AF7, that thing is soo good and killer on bass...think it’s a mutron derivative, it does that super dynamic subby filter sound really well

[@whiskersb5296]

Justin Garcia I think bob weir has had one on his board recently.

[@alexmurphy5289]

If you even slightly liked a pedal, keep it unless you really need to. You'll just regret selling it, but shockingly one pedal I do not regret was my first pedal ever: Dispatch Master by EQD. Too ambient for me, but that's okay. The guy who bought it loved it! Cheers

[@firemarshal2629]

I had a similar experience. I love EQD pedals but the Spatial Delivery didn’t do it for me.

[@alexmurphy5289]

@@firemarshal2629 Yup, I bought a talisman plate reverb instead and I adore it. Done searching

[@paulhoneycutt6633]

Want a MuTron on a budget? Get a Maxon AF-9. I have an old one. They were licensed by MuTron only they run on 9V rather then 18. A friend has a MuTron and I've played them side by side. The only difference I could hear is that the MuTron sustains notes slightly longer.

[@strangequark420]

I've got both an AF-9 and a Mutron, but I find the AF-9 isn't as sensitive. It sounds okay, but the Mutron is like butter to play.

[@paulhoneycutt6633]

Yeah, the sensitivity on the Maxon makes it a little harder to trigger. I wonder what would happen if I ran it at 12 or 18 Volts?

[@MattCorkum]

Your process with the MD-500 is exactly like mine was - I spent ages changing the settings and it just never sound good. It's shocking how much better the Mutron sounds when you flip between them. So, even though I have a very expensive MD-500, I'm looking at getting a Q-Tron Nano or something along those lines! Same thing happened with Univibe sounds. I bought a Unicorn and A/B-ing them is night and day.

[@whiskersb5296]

Regarding the absence of Jerry Garcia, as we all know, the dead were a live band, not a studio album band. They toured Europe in the early 70s and then in 1990. That was the last time, so it makes sense that Jerry wasn't on mick and dan's radar. I imagine that back in 1990, mick was playing the solo from forever man over and over again and dan might have been working on the intro to thunderstruck.

[@blues61]

Spot on Whiskers B, the Dead were a live band but I love the studio albums too. :-)

[@desvonbladet]

I have lived in Europe all my life. I never saw the Dead. I learned to love them from live records and Dick’s Picks. I’m not surprised that Dan and Mick aren’t into them, but not really for lack pf opportunity.

[@LowSlowDisk]

Garcia's heavy Mu-Tron period in the late 70s is also one of their more obscure eras, for non-Deadheads at least.

[@chrisheyes66]

[@DavidDyte1969]

I had a Coron Funk Box years ago and that cheapo little guy was pure magic. Long lost, alas :(

[@LowSlowDisk]

The lamp on the Q-tron is supposed to flash to show how much the envelope is filtering, I believe. It's not a warning lamp. Also, the counter-intuitively labeled "Gain" control doesn't really do what you would imagine gain does, unless the "Boost" is on. Otherwise it is actually what would normally be called the "sensitivity" control. ...says the guy commenting on a three year old video. - -;

[@AncientMarinerYT]

Interesting to hear the step filter of the Spacial Delivery - I had (no longer used) a Korg AX30G bought in '93 that did a step filter thing that sounded very much like that (and autowah too). Will have to go dig it out.....

Funny story. When I was 15 and had been playing guitar for about 3 years, so around 2000. I went into my local cash converters and they had a used Meatball for like £60. Obviously 15 year old me couldn’t afford that, but it’s one I missed out on. Another was a blonde fender bandmaster head. It was in a really junky second hand music shop for £100. Probably just needed a good service and some new caps etc. Tried to convince my parents to lend me the money to buy it, but alas another that got away.

PS-Special mention for the Function F(x) Accufunkture which I've been using as of late. Brilliant auto-wah/filter pedal. Very Mutron-esque and a great price point.

[@actorartistmusician]

Dan - I have a question about the Mysterious Ways (U2) filter. I bought an original 90’s era Korg A3 - and The line 6 Helix has an emulation of the Filter from that box. (They call it a mysterious filter). The Reason I’m directing this question at you is to get your opinion of what is scientifically (or mathematically, or electronically...lol) happening with that particular filter. I’ve taken the Helix and the Korg and played with just the filter alone (taking out the delay, verb, phaser and distortion that are in the patch). Have a listen to the song and hear that the filter is immediately spiking and collapsing and then shortly after there’s a low-end whoosh. The best way I could TYPE the sound is “Chow-Wooof” The interesting part is that the “Woof” doesn’t happen unless you hold the note or chord. So you get the classic “chow”-sound if your doing staccato licks, but the moment you hold - the second filter comes in. I think it’s one of the most interesting uses of an envelope filter in a song by far. (Personal opinion of course.). So - the questions - 1.Do you know of any other pedals that behave this way, or is this unique? 2. Can you posture a guess at what’s happening in that sound? I’ve never been able to duplicate it with anything other than the Korg. (Which the Edge famously used the default preset 76 on that unit for that song.) The helix can get close - but you cant control the length of time between Chow and Woosh, so it’s not exact...anyway - wonderful as always.

[@tlw4237]

The Q-tron + doesn’t boost the output if you set it up correctly. Or it can. It’s down to getting the gain and peak set correctly. Yes Mick you should have read the manual. Attempting to demonstrate stuff without bothering to read the manual is not a good thing. And the Q-tron+ was developed mostly by Mike Beigel - who designed the Mutron - and he says he fixed some things in the Mutron he wasn’t happy about.
