Thanks... glad you got something out of it. I go over that curve tracer here: kzbin.info/www/bejne/bqimgpKVbrmpntk

@@VegasCyclingFreak Thank you!

@@hopemaker2988 It took me months to recover and my eye is permanently screwed up. Hopefully you fare better.

Yeah that's pretty much it

Wow sorry that happened to you. That sucks. I agree, pretty awesome guitars!

I remember reading that somewhere. I know he experimented with different types of wood, and still does to this day!

You can delete the volume control at the input. I like having that but it's not absolutely necessary.

@@mr.kittey2974 I can understand why… even hotter there than here in NW. I can’t imagine trying to do that in the dark. Best I can do for that trail is to start around 5AM. I have to drive 40 minutes to get there. I start at parking lot near visitor’s center. I like doing clockwise, so first thing I do is attack that big hill and get half the climbing out of the way.

@@VegasCyclingFreak It’s almost always cooler before dawn down by the lake than WeatherBug/Windy predicts… but lately much much windier than forecasted.👎 An inexpensive 600 lumen bike lite is more than plenty to light the slowish-steady climb up from the moonlit start of the ride at the parking lot below the Lake Mead Visitor Center up towards Bootleg Canyon. This time of year it gets light enough out to see well before it’s 5 a.m., so the headlight is really only needed for the first 20-30 minutes of the ride, and the first light views of the lake while climbing up the dam railroad grade are surreal. A nice thing about starting out at around 4:30 a.m. is that I don’t get hit with any direct sunshine until the halfway point of the ride when cresting the Sisters, but the low rising sun is directly in my eyes until I make the right turn onto the old derelict park highway section of the RMLT.😪 And it only really begins to feel hot out during the final climb of the ride from the camp grounds up towards the Lake Mead Visitor Center.

I'm not sure. I just know it goes from W. Centennial Pkwy all the way past Bradley. It stopped on either side of US 95 before they finally finished all these overpasses going every which way. I think it took them at least 4-5 years to finally get all the pieces of that trail connected together.

@@VegasCyclingFreak: Are you heading East from Summerlin towards Jones Blvd or back West towards Summerlin and Lone Mountain? Thanks again.

@@carbonsnail014 East towards Jones

I did an after work ride for an hour last week - avg temp was109 and max was 115. Not fun!

@@VegasCyclingFreak The Freak name checks out!! 😅 God bless you, man!!

@@Sammywhat Ha ha well I am a cyclist, a guitarist, a DIY guitar related stuff person and an engineer. I try to show people via POV video places to ride in the Las Vegas and surrounding areas.

@@murkyhole1 that’s interesting, thanks for sharing your experience with that

lol the sound is totally subjective - whatever equipment you are using is far more impactful than the guitar on its own. It is different than most guitars, you just have to learn how to work around that. Was never a problem for me. There's a thing called a tone control, and it helps to use it. There are some replacement parts available, but yeah it's not like if you have a Fender/Gibson where everyone and their brother makes a replacement whatever. Also is not a problem if you actually take care of your guitar.

@VegasCyclingFreak don't disagree with any of your points. But at the end of the day, the brand folded. They were not successful. They were too expensive and competing with known instrument brands with decades old proven records. The market spoke

@@contrabandjoe7974 Yes and no. They seemed to have been doing OK until Washburn acquired Parker. Things went downhill really fast after that. I think they wanted to make Parker super profitable overnight and ignored the fact that Parker was a niche market that appealed to a certain kind of guitarist. Anyway, I like the fact that my '95 Fly weighs less than 5 lbs still has no wear on the frets!

A while back the cover came off mine and it looks to me like it's just enameled wire wound on a bobbin which is placed inside of two ferrite cups. I took a picture of it. www.diyguitarist.net/Images/FaselVintage.jpg

@@VegasCyclingFreak Mine is a 1967 Fasel that came in an Italian made Top Logo Crybaby. I pried off the cup the other night & it sure as shit has a torroid core. It's a cherry red cover with cherry red back plate instead of a white back plate. The later 60's & early 70's red Fasels I've seen all have the white back covers. It looks like there are 2 different versions of vintage red fasels.

@@VegasCyclingFreak Yeah, yours doesn't look much different than a stack of dimes or the inductor that's inside the TDK 5103 brown cube! I got ahold of an original small hole Halo inductor & put in in my Crybaby & two nights ago I put the red Fasel in a board I built for a 90's VOX 847.

@@markmarshall7939 Huh . That is something I was not aware of! Two different versions of the "vintage" red Fasel. Who knew?

@@VegasCyclingFreak What's your email address? I can send a pic of mine. I had to mount it laying down due to height clearance issues but you can still see the red rear backing plate especially where the two soldering lugs come out of it. Now I'm thinking I should just put it back on the original board in the Crybaby because it might be something even more rare than I thought.

The voltage regulator actually runs pretty cool. I did drill a lot of holes in the enclosure to make sure it stays cool.

Nice find

What kind of noise? Motor-boating or a hum/buzz?

I can only remember one case where a part on a PCB went bad, on the forum back in the day. PCBs have gotten to be be remarkably reasonable in price these days, nowhere near what it used to cost.

Thanks for the info. Back in those days manufacturing wasn't as consistent as it is today. All sorts of variations to be found in "vintage" guitar pedals.

@@VegasCyclingFreak I found your website ! Thank you for all the information.

@@leonardo.rafael Cool. I made this video during the years I had taken down the website. I resurrected it last year.

@@VegasCyclingFreak In Makossa is used as a Yoy with a guitar, but (I asume its the same pedal along the album) is used as a Wah in Hibiscus with a keyboard and in Nights in Zeralda is used with guitar and with trumpet. Indeed Wah was created for trumpet ! kzbin.info/www/bejne/iWe5dmlsgt2hodUsi=XYso50C4jZ1GI5XV

@@VegasCyclingFreak is this the Yoy in a guitar ? kzbin.info/www/bejne/pWW4qJWqpZJnjaMsi=16PeN5t6tlwU1dg7

I did hear that complaint about the upper horn by a few members at the Parker Guitars forum back in the day. Never was really a problem for me. Yeah, the asking for Parker guitars are like to 2x to 2.5x what they used to be. Seems like everything else is outrageously priced these days. Where I live we have 20% inflation at the moment.😕

Yeah I did some of those. Most people ride 50/34 compact cranks with 11-28 or 11-32 cassettes. I use 11/32 cassette and compact cranks for anything with a lot of climbing.

@@VegasCyclingFreak: Are all the bike shops in Summerlin competent at working on Campy stuff? Also, do you prefer riding out to Red Rock or staying on the Beltway bike path more often? Is it common for Summerlin riders to do both Red Rock Loops twice during the week?

@@carbonsnail014 Campagnolo is very rare here. Never met anyone that didn't have Shimano, FSA or SRAM on their bike. I don't really do the loop anymore, too many people but when I did I went right at 6AM on a Friday when no one was there. I do 215 trail sometimes but it's more of an e-bike haven these days unless I am out at like 5AM.

@@VegasCyclingFreak: What other locations are there to ride in the area besides the ones mentioned? Thank you.

@@carbonsnail014 Anywhere you have a bike lane on the street. Las Vegas likes to boast that there’s 400 miles of bike lanes here - all of them are unprotected.

That's what I thought when I first started on this journey, but that's not how it actually works. It's based on the principle of feedback sustain.

@@VegasCyclingFreak I should have expected that it wasn't as straightforward as my first ever guess on the matter.

Interesting… thanks for the info

🤣

I believe in part 3 I go over this capacitance thing. We are talking about a total of only 10-15mH or so of inductance in this circuit, and not very many turns of pretty heavy gage wire on each inductor. That's a very tiny amount of inductance and it will have almost no self-capacitance. It would only be picofarads, probably less than 100-200pF (and some think I am way high in that estimate). Same with the nichrome wire, almost no self-capacitance there with a total DC resistance of only around 6-7 ohms and an air core. Allan's unit is pretty much a pure resistive load. No LRC circuit like most of the "attenuators" made today. Closest thing to it is the original "Power Soak", but that uses a truckload of ceramic capacitors. Actually is closer to the "Altair" which I believe used the same nichrome wire as you'd find in a toaster. Still trying to see what the inside of one of those looks like. Anyway, if anything, the steel baseplate will slightly cut the higher frequencies but it won't be anything dramatic. It would be like the difference between a 10 and 20 ft guitar cable. It appears that Allan used both steel and aluminum baseplates, and some of his units were in an aluminum enclosure and some were steel (as far as I can ascertain). Also some of them were "custom" units, with volume and low/high tone controls. That tone control scheme Allan came up with is simple, clever and very effective.

@@VegasCyclingFreak This is one of the oldest errors made with impedance measurements. Any misunderstanding of which component is the dominant contributor to the impedance will lead to large errors in the other components. E..g. misunderstanding dominance can turn a 20uf capacitor into a 100pF capacitor easily. The exact same thing was made in papers in a related field by a gov researcher who were just a bit sloppy with impedance measurements yielding huge capacitances as a result. This turned out to be false as I proved later on and allowed me to file patents solving a 50 year old problem. This was a highly qualified individual. I am sure you make the same mistake. Your actual transfer function measurements shows that you are making a mistake, and to me it is clear that your impedance measurements are wrong. So which impedance/LCR meter did you use to measure the output impedance as in your video where you got these huge capacitances ?

NOT THE POINT OF THE VIDEO. Did you read the description?! There's 16 different preamp modules and two channels... you want me to do a 2-hour long noodling session so you can hear all the different possible combinations? Give me a break.

I actually started out on a Nitefly Mojo, which was a pretty nice guitar. It was better than anything else I ever had up to that point. I still wanted the Fly, just had to get in a financial position to afford own. 16 months of unemployment 2009-2010 and almost being literally homeless takes a while to recover from.

Agreed

That may be. I'm just going off of all the stuff I saw on the internet around 2003 when I created many webpages concerning the Convertible. Most of what I read is that they were unreliable and prone to various problems due to the preamp module design... the method used wasn't exactly bulletproof but there was really not a better technology to use at the time. I made this video after I had shut my website down, a few years before. I resurrected it about 18 months ago now -- www.DIYguitarist.net

No sir

Perhaps this page I uploaded to my website will help - diyguitarist.net/PDF_Files/ImpedanceTester.pdf

That's far beyond my physical ability, but I appreciate the thought. It's more fun to descend Deer Creek Rd from Lee Canyon side. I've encountered some very nasty crosswinds going down Lee Canyon. kzbin.info/www/bejne/i4OldHmdj8ydqJY

You mean like this prototype? Was on ebay many years ago now... www.diyguitarist.net/Guitars/FlyProto.htm

Yep... I've seen some of the jigs Ken Parker has made on his KZbin channel - he's kind of a machinist too. Here's Ken's KZbin channel for anyone interested in what he's doing these days: www.youtube.com/@kenparkerarchtoppery9440

Back in the day they had a MIDI Fly but there really was no demand for it. Very few were made.

A lot of it is trial and error. There are some basic module combos in the owners manual for certain "tones". I have a lot of info on the Convertible at my resurrected website - DIYguitarist.net (used to be DIYguitarist.com)

This not the same as a guitar pickup, it's not microphonics either. "Potting" it won't do anything to change it. It's called "mutual inductance", where the field generated by the current going thru one of the coils influences the field of the other coil. It's likely a very small factor in the overall scheme of things. How you orient them in relation to each other makes a difference and it's possible to even eliminate it, but not possible in a one rack space configuration.
