I love English Muff'n (the pedal too )
Ok enough of the yuks. I got mine for a song ($100 US) and man best buy I ever made.
Yes it's big, yes the wall wart is a pain but the tone you can get by switching tubes is outstanding.
I must respectfully disagree with a pervious poster, fuzz=yes, put some 12AX7's in it and crank the gain, sweet.
I use it for my bass and guitar, not sure which one I like it on better.
Get a used one, not because it's not worth the price new, because why pay full pull if you don't have to.
If mine ever gives it up, I'm going to get another one!!
