Like a lot of (bass) players, I went for the AW-3 looking for that classic Mu-Tron sound. You won't find it in this pedal, at least not to my ears, but what you will find is that it possesses it's own definition of the wah sound. Plenty to be heard here, and the Humanizer adds some interesting sound ideas with its various vowel settings. So far, the funkiest sound is to dial the decay almost flat and the mode to sharp; play around in this area and you're bound to get a nice, although a bit "modern", drippy wah sound. Cheaper than some of the other bass-centric effects, BOSS offers good bang for your buck: affordable, solid, and effective...give the AW-3 a run before blowing your cash on something with less character or extravagant price tag.

I had initially purchased the EHX Q-tron + because I wanted a funky sound for my bass. After all, there are countless articles about how the Funk Masters use this device (maybe the original Mu-Tron is the real answer, but I'm not spending the money on that vintage tool). The Q-tron + sucked my tone and volume, and also created a noisy sound similar to wow and flutter. Not what I wanted. This BOSS AW-3 arrived yesterday, and after comparing it to the MXR M-188 (Bass Auto Q Auto Wah) I decided to keep the BOSS. Several reasons: this device has many tonal variations, is noise free, built ruggedly, easy to use, and practically every tweak of the dials produces sounds that are pleasant. From subtle to extreme, this pedal is worth it and is cheaper in $ than the MXR box. It's made for both guitar and/or bass, has separate inputs for each, and even has another jack for an expression pedal for manual wah control. I don't plan on using the latter, because I get enough sound variations by using different dynamics with my right hand. Hard, soft, and slapping/popping produces different sounds. I use my Micro POG just before the BOSS to further enhance this already cool pedal. The two together are greater than the sum of their parts.

I just purchased this today and in my opinion its pretty good. What I enjoyed about it is that you don't constantly have to stomp on it. One press and the wah-wah is on. For the price here it seems pretty reasonable. Just be sure to pick up the extra cord to connect it to your amp and guitar.

This wah does what a wah is made to do. It wah wahs for you, enabling you to focus on playing rather than rockking your foot. Its tone is pretty convincing and have found 3-4 very usable settings on this BOSS. It's very musical in the right hands...give it a week before rating. It takes some time to find the sweet spots.

I just played this pedal at a local guitar shop and I was extremely dissappointed. I used it on a 6 string bass because thats whats I usually play and no features sounded good. There was a decent autowah sound when you messed with the decay to a very very exact setting and even that sound got old fast. I have the aw-2 and that pedal is much better then it and im not even too happy with that pedal because it lacks alot of the low end I demand out of my sound. This pedal had a better range as far as the low end went but it still was just lacking in sound quality. I played it out of an ampeg svt head on an ampeg 6x10. The sound was just lacking. There were more options then the standard pedal but the options weren't that useful. I use a bootie-collins snaring dog wah as well and that wah with the autowah achieves more sounds then this sounds. The overdrive/distortion settles were decent as well but the range was very very lacking in all the differant ways you can mess with that setting. and with the boosy collins wah it has a fuzz on it and its adjustable as well. **I used the expression pedal with this pedal for most of the time I was playing with it and it improved the every option on the pedal and it was still lacking. I mean maybe I'm being to critical but I have alot of pedal and I really look for as many diverse sounds as possible and this pedal would never earn a spot on my pedal boards....
