Electro-Harmonix Classics USA Big Muff PI Distortion / Sustainer Guitar Effects Pedal

Sound Quality

I play my LP through a chain of pedals that include this box, a Keeley moded Boss BD2, a wah pedal, and a tube screamer into a Fender amp at times or else a Mesa Lonestar amp. I can dial in the sound I after. However IMO when you increase the sustain too much it sounds very solid state/artificial.


I think the pedal is quite solid and will hold up. Nince big knobs with a red indicator light. However I believe there is real potential to scratch and dent the bright aluminum surface stomping on the button. The battery compartment door is secured with a small screw. Nice feature unless the battery dies and you don't have a screwdriver to remove the screw. It does have an AC adapter jack that overrides battery use, but unlike other pedals, it uses a small mini jack instead of the more typical adapter jack.

General Comments

I've been building my pedal collection towards getting various sounds and tones. I do like this pedal because the three knobs provide a good variation/latitude of tone, sustain and fuss. It is not an expensive pedal and I recommend to anyone who is after the fuzzy sound.
