MXR M81 Bass Preamp Tested on BASS

[@gab.lab.martins]

Just came from another demo where the guy was fiddling with the knobs like a 2yo with a new toy, no idea what he was doing. I posted a comment of how a proper demo should've been done, and now I'm watching you do EXACTLY what I wrote. Thank you so very much. This is how demos are supposed to be done.

[@JuankaTrujillo]

Thanks a lot!!! I love your comment so much 🙏

[@T3L3cast3r]

Thank you very much for this clear and concise product demo! Five years later, it is still super useful for someone like me who is considering buying this preamp.

[@JuankaTrujillo]

Thanks so much for your comment!!!🙏

[@lext4374]

One of the best demos I've ever seen. Thanks. I like how you put the stuff back in the box at the end.

[@trujillobeats]

Thanks a lot!!! 🙏

[@BlackRootsAcademyOfSoul]

The best demo video for this particular pedal that I've watched. 👌🏿

[@JuankaTrujillo]

Thanks so much!!!! 🙏

[@trentnichols5075]

That was the absolute best demo of anything I have ever witnessed!!!!

[@JuankaTrujillo]

I appreciate your comment very much!!!

[@discotechwreck]

Sample setting three was sick! Thanks for this great demo as it's great to hear just the DI straight into a soundcard for once

[@zulu5157]

Very good demo. Answers all questions without using one word. If you don' t need much effects and want to have a pure basstone than this should bei your choice beside a good compressor and a tuner pedal.

[@JuankaTrujillo]

Thanks so much for your comment Zulu 5!

[@CarlosJimenez-pw6vq]

The clearest bass preamp that I know! Fantastic!

[@JuankaTrujillo]

Carlos Jimenez Thanks for comment and watching!

[@zulu5157]

It is crystal clear and this pedal can give you lots of Boost in every frequency for every Bass.

[@RootMcRodent]

I own one of these. Great pedal! I use it with my Fender P-bass. I like it because it does not take a lot of space on my pedal board. Buy it. You will not be disappointed.

[@kendalllewis3992]

I know it's kind of off topic but do anybody know of a good place to stream new tv shows online ?

[@brodierussell74]

@Kendall Lewis try FlixZone. Just search on google for it :)

[@ramonizaiah8454]

@Brodie Russell Yea, have been using flixzone for since march myself :D

[@kendalllewis3992]

@Brodie Russell thanks, I signed up and it seems to work :) I really appreciate it!!

[@brodierussell74]

@Kendall Lewis glad I could help xD

[@mackymaca]

The only pedal I never gig without.

[@1998kid1]

Hey man how would you use this to gig. Im new to this!

[@godzilla964]

Could I be able to send a dry signal from the quarter inch output to my amp while send the preamp signal from the xlr output to a mixing console?

[@LetzBeaFranque]

Excellent demo. Thanks!

[@chrisw5742]

Just got this pedal in the mail. Thanks for the great review :-)

[@JuankaTrujillo]

Thanks a lot for your comment!!! I hope you will enjoy your pedal, It´s great!

[@MrFender64]

Thank You very informative good demo on what this pedal can offer. Thinking this is the one to buy.

[@catboyzee]

Nice demo. The eq on this pedal is very musical and transparent.

[@JuankaTrujillo]

Thanks so much!

[@Stratisfied22]

The Aguilar tone hammer, Xotic tri-logic, and Phil jones bass buddy are the only outboard preamps I would currently use. Every other preamp Ive tried are either too noisy or sound worse than my amp which is an Ampeg micro vr with the two matching cabs that does sound great. The Phil Jones is expensive compared to the other two but it's a serious piece of equipment that sounds amazing and is also a practice head that can push a cabinet with no problem. Pretty cool.

[@alfieharries]

Perfect demo, thankyou

[@JuankaTrujillo]

Thanks a lot!!!

[@ktfo4620]

I'm glad it was "tested on bass."

[@DavidChampoux]

EXCELLENT demo!!

[@JuankaTrujillo]

Thanks so much David!

[@burningkarma]

Been thinking about trading/selling for one of these.I have the MXR M80 which I like quite a bit but don't really need the distortion feature or XLR out as I use my Radial J48 which is a freakin killer DI Box. This unit sounds like a great clean Preamp with a little more tweak-ability than the M80.

[@boazdarmawan4995]

thank you for share it..

[@ninjanugget8781]

I got the signature Flea Jazz Bass with passive pickups, will a preamp pedal (for example MXR M81 Bass Preamp) give the same effect/opportunities as active pickups?

[@JuankaTrujillo]

Is more like if you have an active preamp onboard, you can get a hotter output and more eq settings available

[@mendoncapedro]

Did you try the Flea JB with MXR M81? I'm in the same situation!

[@ninjanugget8781]

@@mendoncapedro Not yet :/ Fresh strings and MarkBass amps does it for me, I love those amps. But I am still thinking about it! Would be nice.. But then there is the money..

[@mendoncapedro]

NinjaNugget can you hear well at an outdoor concert? I'm afraid of not having that low frequencies... What is Your Stack?

[@ninjanugget8781]

​@@mendoncapedro I find MarkBass combo amps to be very nice outside too. The amp cuts through the mix/band, and you can boost the bass/low freq on it without it sounding muddy or unclear. I also use the "MXR microamp" pedal (which I heard Flea also use/used). I use it to boost the low end when slapping and when I play some lead bass-lines. Also nice when using a pick or in general when you want to get the low end more clear and punchy

[@jmachado7641]

Nice review, but just one question: is it possible to use the xlr output to plug in into the desk, and using the jack output to a stage amp, like a parallel processing out?

[@JuankaTrujillo]

Thanks! Yes, I use it on this way on live

[@jmachado7641]

Thank you sir!

[@rgdhu92]

I use it this way also. DI to front of house without eq and eq out of 1/4 inch jack to my amp

[@adicelviteaz]

Hi @@JuankaTrujillo , very nice video:) Just to make sure, are you saying it is possible to send the EQ-ed signal through the XLR out and at the same time also an UNAFFECTED signal through the 1/4 out to the amp? If yes, do you have to open the pedal and adjust the internal switch? Thank you!

[@JuankaTrujillo]

@@adicelviteaz Thanks for your comment! No, sorry, Its the exact opposite, you can use DI with or without eq using Pre/post switch, but when the pedal is ON, the eq always affect to the 1/4 output

[@TheMidnightRiders]

This is a great demo. But can someone explain to me the use of both input and output level? Aren't they just volume control or I am not getting something here?

[@JuankaTrujillo]

Hi! Thanks for the comment! The input level is the level that you use for attack the preamp, (is not exactly the same, but is like the gain Knob) and the output is just the general volumen of all the sound

[@1thess523]

This was a really good demo, i just got a Hartke LH500 which is a basic Bass, Treble, and Mids with a Bright switch and a limit button, i run it through a SWR Working Man 2x10 and a Gallien Kruger 4x10 cab set up with a Sterling SUB Ray active bass and it sounds pretty good but i am looking to add a preamp just to make it sound even better. My first taste of a preamp was the Sansamp which totally surprised me because the guy at Sam Ash demoed it through an Ampeg 1x15 combo and it sounded amazing, well i started looking into preamps and have seen some different good sounding stuff but they are pretty pricey but this one if the price is correct that someone mentioned ($169) i think i might get this. I pretty much just play melodic and pop punk plus some 90's style emo (jealous sound, hey Mercedes etc but not exactly sounding like them) so i don't need distortion and i play finger and pick as well. Thanks for the demo because I think you sold me on this, God bless

[@alskndlaskndal]

Thanks for the demo. You can get some good tones out of this pedal. So is this basically an EQ pedal with a direct out, or does it affect the sound in a different way than an EQ?

[@JuankaTrujillo]

Reluctant Dragon It´s just an EQ pedal with DI, thanks for watching!

[@xemuz]

***** excuse my ignorance, what's a D.I.?

[@szaki95]

***** D.I. = Direct Input. With a DI box you can plug various things directly to microphone input. In this case a bass

[@MelodylaneLou]

OMG....could you write the best practices manual for KZbin and product demos! great job. Less talk, more rock!.

[@JuankaTrujillo]

Thanks so much for your comment!!!

[@markesquivelarvizu6942]

Are the output (1/4") and Direct Output (XLR) both a part of the preamp circuit?

[@marcopanetta3510]

Is it possible to connect the bass to this pedal and then go into a guitar amp?

[@trujillobeats]

Of Course! is the same that using a bass amp. I often use an fender SuperSonic head but with an Ampeg cabinet. Thanks for watching!!!

Nice nice review. Thanks for that. Just out of interest: Do you still use the M81 or did you just demo it?

Thanks so much H. Hetschko!!! Yes I am still using it

[@sulikojunk]

Hello! Can I use this with double bass?

[@ABRAXAS37]

love the riff by the way lol

[@Helljaybass]

What bass was used?

[@seanparry2k8]

is the input dial like a blend dial ?

[@JuankaTrujillo]

No, is just the gain signal you put it on it, you can use it with or without the mxr sound, but not blended

[@seanparry2k8]

Ah I see cheers for letting me know

[@SeuRafinha]

I'm playing in 3 bands with differents amps and it's hard to get the tones I want everytime we have to change music studios or amps. I would like to make my sound more standard playing all amps in flat. Do you think this preamp will help me?

[@martinsleonardo33]

good afternoon what's the value of this pedal to send to brazil

[@zawszebadzsoba798]

Inside is a Noise Gate?

[@santanajackson6160]

the ampeg analog bass preamp pedal is better than the mxr , although mxr is my pedala of choice but the ampeg preamp sounds fuckin awesome . so the ampeg preamp will be my preamp pedal of choice but everything else will be mxr

[@NtWarlock]

Great

[@adrianjamin-dq9ru]

whats the direct out for?

[@JuankaTrujillo]

Is for send the signal to a PA system in concert, or for recordings sessions, plugin in direct to an interface with line signal. Thanks for watching

[@adrianjamin-dq9ru]

@@JuankaTrujillo whats the pre/post for and how does it relate to the direct out? can i plug the amp on the direct out?

[@alfrednougat7884]

@@adrianjamin-dq9ru Well often when you play a live concert, the sound coming from the bass amp on the stage is just so that the band can hear the bass, it is not for the audience. The audience will instead hear the bass from the P.A. speakers, not the amp speaker. So oftentimes you will go from a D.I. output to a mixingboard and then to the P.A. speakers. So when you are playing a live concert, you can plug the pedals normal output to your bass amp on stage, and the D.I output to the P.A system. So you have 2 signals going out from the pedal at the same time, one for stage amp (band) and one for P.A (audience). The pre/post button selects if the E.Q. knobs on the pedal affects only amp sound (pre), or both D.I. AND amp sound (post).

[@adrianjamin-dq9ru]

sansamp bass driver still the best thanks you save my money hueheuheuheuheuheue

[@jostonpowell1346]

I own one as many people do but some of the newer ones like B7K or B3K sound so much better. Guess it really depends on the sound you want as well.

[@pennywiseRJ]

Joston Powell yeah i know, i saw some demos on youtube, in brazil we dont have B7K acessible, and when you see one for sale, is the price of 2 sansamp bass driver huehuehuehuehuehuehuehue, my country sucks

Is this a D.I or not?

Yes, with EQ

[@christiankurtboutot5658]

pffff useless...just try the Ampeg classic bass preamp.... you will have a strong mental shock which could push your girlfriend to call an ambulance to bring you to rehab !!!!! lool

[@JuankaTrujillo]

XD, Its depend or what sound are you looking for, the ampeg add different tone to your bass and it could be great or not, depending of the kind of music were you doing or the sound that you were looking for.

Ya, damn near 69 years of failure. What could Leo have been thinking? And all those millions of P-basses sold to all those unsuspecting silly rubes. Truly a train wreck all around. And then when you plug them in and they sound so cool, but really aren't because you said they were a failure. So I guess they must be.
