Audio Electronics MC-404 : One of the best wahs

I really like this one. It's a keeper. Top quality stuff. I mostly use the Red fasel (opened the red Q trimpot all the way for really nice wide sweep). Sometimes use the yellow fasel when I like brighter sounding sweep, or to cut thru better (higher freq).

Mostly have the boost on a little. Boost is really transparent and great. It is easy to set the boost up some dbs without making high gain amp squeal.

Works good with other pedals, but note that If wah is used example in front of fuzz pedal, then the fuzz pedal should have good buffer (buffer should kind of mimic guitar signal) or your fuzz will squeel. Same might go with other distortion type pedals so check your stuff.

Something negative.. well it is a bit heavy and the bottom shape makes it difficult to use velcro and stick and really hold it on your pedalboard. I have used cable tie to stick it to mine.

I have used this wah a lot and it still looks and works like it's brand new.
