I decided to run my Eric Johnson fuzz into my 5f6a a few days ago. Before that I had only plugged a EH Memory Boy in for a bit of subtle ambience. The fuzz sounded so bad I thought the battery must be nearly dead but no such luck. Suffice it to say I was shocked. The EJ fuzz always sounded great and the Bassman is jaw dropping good. Pair them though and it sounds like amplified beer farts! Anybody else have a similar experience?
