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.

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!

Excelente Pre, muy limpio si es lo que buscas. También lo puedes usar como paramétrico al final de la cadena.

Muito bom.

I tried a lot of preamps. The MXR M81 has all these features that made me buy and keep it. - Sounds great and doesn't change the character of my bass of amp. - Can run on battery, phantom power or standard A/C adapter. - DI on board with pre/post switch and ground lift. - Plenty of headroom. I can run direct into a power amp if needed. - Small form factor (like a Phase 90). To me this sounds a lot like a Sadowsky preamp. The MXR M81 is smaller than the Sadowsky SBP-1 but has sweepable mids and more headroom. It's more feature rich than the smaller Sadowsky SBP-2 having the advantage of a DI with phantom power and can run on a 9V battery or A/C adapter. Finally the MXR M81 is cheaper than both Sadowsky preamps. Great preamp!
