Big Muff PI USA : A classic!

I love this pedal for its distinctive sound and its a great price for US manufacture.....!

It controls give a really wide sweep of the effect and it has that really great analogue feel that some newer types seem to lack..even though they are analogue!

I like that you can adjust those giant knobs on the fly with your foot!

Oddly,I prefer it through SS amps not tube..no idea why..!

Downside?..it doesn't actually feedback that easily though it sustains like crazy...

The switch went funny after about a years fairly heavy use...but as ,everything is so big and '70's and easy to take apart I found I was able to dismantle the switch and click the contacts back into place so its fizzing and fuzzing away nicely again...

Its no longer a fixture on my rig as I've started to use a Boss FZ3 instead but really its a pedal that's worth having around just to have fun and experiment with from time to time!
