OVERVIEW

Bring out the best of your bass tone.

The MXR Bass Preamp combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedal board space. Use it to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. Dial it in just the way you want it and send it straight to the house-pre or post-EQ-with the built-in Direct Out.

The Bass Preamp features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange-from 250hz to 1khz-for extensive tonal flexibility. It's all delivered super clean with high headroom thanks to our own Constant Headroom Technology, and you can use the PRE/POST EQ switch to set whether or not your Direct Out signal is affected by the Bass Preamp's EQ section. And of course, the Bass Preamp features a GROUND LIFT switch in case you encounter ground loop hum.

The Bass Preamp is factory preset to operate in ¼" out buffered bypass and Direct Out active. For players who only want to use the ¼" out, there are two internal switches that disable the Direct Out and ¼" out buffered bypass for true ¼" out bypass mode.

FEATURES
  • Separate INPUT & OUTPUT level controls
  • 3-band EQ section with sweepable midrange

Comments about MXR M81 Bass Preamp:

This pedal is fantastic. It's very clean, very transparent, and highly versatile. If you're looking for a good, clean sound to sweeten your tone this is it. I wanted something that had good mid control and this preamp ended up being better than I could have hoped. For those bass players out there who like to mix your dirt with your pre this obviously won't work for you. But if just need some extra tone control this pedal is hard to beat. I officially retired my BDDI.

    Comments about MXR M81 Bass Preamp:

    I purchased this to help sculpt my tone on my electric upright bass. The M81 really does the trick. It tightens up the bottom end perfectly and trims the treble in a musical way. The selectable midrange control is powerful but not too dramatic. I will end up using this for my bass guitars as well. This preamp is great to have for everything bass related.

      Comments about MXR M81 Bass Preamp:

      Just threw this guy on my pedal board in replace of the BULKY Aguilar Tone Hammer... DEAR LORD. IT IS SO MUCH BETTER THAN THE TONE HAMMER.

      Ignore the hype of that company.
