From funky to extreme, this pedal does it all!

For adding character to your bass tones, check out the MXR Bass Auto Q. It'll instantly funkify your riffs with authentic Crybaby wah and add a lush shimmer to sustained notes and chords. Turn the simplest rhythm and lead lines into complex textural effects, and take your music into uncharted territory. 5 knobs give you infinite control of the Bass Auto Q: Range controls the frequency floor of the effect; Q modulates the intensity of the wah by adjusting the bandwidth of the filter from a broad, subtle curve to a bright, sharp peak; Blend controls the mix between the wah and shimmer effects; Decay controls the transition between wah and shimmer; Rate controls the speed of the shimmer, from tremble to shriek; and Volume controls the overall effect volume. A rugged footswitch lets you bypass or engage the effect, and graphics glow in the dark to make this pedal easy-to-read on an dark stage. Housed in a virtually indestructible zinc box and powered by a single 9V battery or optional Dunlop ECB-003 AC adapter.

Nice pedal

Posted by Anonymous Musician on Nov 30, 2009

Experience w/product: I own it

Reviewer's Background: active musician

Reviewer's Play Style: Mostly straight up, old school funk with some jazz

I am a bassist with 40+ years of experience. I generally don't like effects. I have sent most of them back or thrown them away so I am pretty cynical about them. I hate it when they mess with my natural tone. This is a pretty good/functional pedal and I will keep it. Controls are straight forward and actually do something. I don't think that it is "true-bypass" but it does not alter natural tone to any level that I can perceive. That is the best part of this review. Otherwise it does what it is supposed to. Even the shimmer thing adds a little bit of fun.

Great box, but I prefer the BOSS AW-3

Reviewer's Play Style: Rock mostly (classic to modern)

I posted a review of the BOSS AW-3 (the pedal I kept) because I had done a side-by-side analysis of the two and found I liked the BOSS better. However, everyone's tastes are different, so this box is worth trying. Built like a tank. Costs more than the BOSS pedal and doesn't have the variations in sounds nor the same quality of sound in my opinion. The 6 knobs are spaced nicely and easy to access, but not entirely what I wanted. Had I not had the comparison, I would have kept this pedal.

The MXR Bass Auto Q is a great pedal for that super funky bootsy style bass playing. Hook up an Electro Harmonix Bass Balls for killer tones and effects mixed with the shimmer effect.

This pedal is the best wah pedal you can buy for the money hands down. The quality of its sound is amazing and it is built like a bullet proof tank. Every pedal on the planet should be made like MXR makes theirs. Does not lack anything period alright you gotta buy a power supply but thats it.
