MXR M81 Bass Preamp Pedal

It is a very good and versatile preamp because it works with phantom power, too. I returned the first one due to noise, but it turned out that my house had some issues with the electrical framework. I bought it again. It is small and very useful. Sounds very good too.

It brings an old bass cab to life, very clean sound no buzz with a big sound/volume boost. Small and compact, easy to carry with a strong build quality. Spread over a few payments with a good discount it was a very good buy.

Awesome pedal, took a while to arrive and I did pay for express delivery!!! But the pedal is great, easy to use and you can get pretty much any sound you want out of it. Haven't tried it in the studio yet but I use it for all my live gigs, I've set it up for an awesome slap sound but I pretty much just leave it on most of the time coz it sounds great!!!!

I bought this, based upon reviews I had read, to augment a Peavey passive 5 string bass with the aim of getting a more active sound out of it and, to that aim, I have to say it that it does the job well. I'd probably have been expecting rather too much if I thought I could get the tone of my faithful old Aria SB1000; I think that when a circuit is built into a guitar, the signal path is attenuated and reinforced much closer to the source, i.e: the pickups, and that makes a big difference; you're pushing a heftier signal down the cable so the losses are less. Thus, being at the nether end of the cable, it's not going to suddenly transform your passive bass into the "bass-of-doom" of the late, lamented Jaco Pastorius, or sound like that famous Welshman, Pino Palladino, or yet give you the grunt and drive of John Edwards on "I am the Phoenix" - and I suspect he plays Alembic: not cheap. But what it will do is give you a good boost and excellent control over your whole range of tone - and without distortion ! Anything else you need, you'll have to add other gadgets to achieve. So yes, a worthwhile addition to the bassist's armoury.

This is a great pre-amp, with warm tone and parametric EQ. I've not used the DI feature yet, but I'm confident that it will provide a good, noise-free signal. The pedal is well built and has a great many useful functions.

Brilliant. Works really well

Awesome pedal. Brings new tonal life to my 70s Fender Jazz bass. Love it.

Pedale fantastico, totalmente neutro, per chi vuole sentire la voce del proprio basso senza simulazioni varie.

Ich bin durch Tests und Videos auf Youtube auf den MXR aufmerksam geworden. Kaum bestellt, schon da, wie gewohnt bei amazon prime! Der Preamp arbeitet absolut clean ohne Rauschen oder sonstige Störgeräusche. Der EQ lässt sich sehr musikalisch einsetzen, vor allem der Mittenregler hat es mir angetan, damit wird die Präsenz im Mix wirkungsvoll angehoben, die Höhen klingen fein aufgelöst und bei Bedarf drücken die Bässe mächtig. Wir spielen in unserer Band mit InEar Technik. Damit klingt der Bass auch auf dem Kopfhörer sehr klar und detailliert. Durch den integrierten DI Out kann das Signal direkt ins Pult gehen, weitere Verkabelung entfällt damit. Klare Empfehlung, das Geld lohnt sich!

I got this for playing a few different bass guitars direct and with headphones, so I can't speak to what this device can do for playing live, but I absolutely love it. I have an Ibanez Mikro bass (extra short scale) that I improved by adding Seymour Duncan pickups, but it still sounded a bit thin to my ears. This preamp completely kicks it up to a level of power and versatility that vindicates my sticking with this somewhat silly little bass. I can boost the low and low-midrange without losing crispness and clarity. And I don't have to use the tone controls on the bass, which always strike me as unsatisfactory. I'd previously tried a "bass boost" pedal that was basically equivalent to overusing the tone control and then amplifying that low but dead sound to dubious effect. Another of my basses is an entry level fretless with stock pickups that I haven't upgraded yet. This pedal does greatly improve the sound, but the effect does seem to be dependent on starting with quality pickups for the best result, so it doesn't magically fix an inherently poor tone. My third bass is an old 60s era Japanese EB-2 clone, with one of those lovely mudbucker pickups. That pickup is a force of nature. It basically turns you into a god of thunder, but it sure is muddy. I've always wanted to find the right way to enhance the high end a bit to give the sound a bit more definition or something. This pedal enables me to do that very nicely. Moral of story: if you keep your bass's tone control all the way open, you can use this pedal to shape the sound without losing anything, as long as your pickups are providing a good enough starting point. There is a slight learning curve, such as using the dip switches hidden behind the battery cover, learning whether to use the direct output or not, but it's not difficult. The only problem is that the pedal does not come with a proper manual that explains any of this, so you've got to search online for the manual.

Tenía las esoectativas altas y las cumplió con creces. Se pueden obtener varios tonos con este pedal. Tengo varios pedales pero este y el compressor son los indispensables. Es una inversión que vale la pena.
