I know opinions are like $(*^%&^%, but I recently got my hands on the MI Audio Crunch Box pedal. Considering I tried just about everything that's come down the block; I've gotta say this thing sounds great. I love the way my Mesa Boogie sounds cranked up, but for home recording, it can be impractical at times.
The Crunch Box sounds killer at any volume which will come in handy. Also, if you have an amp that's sounds super-clean, but not-so-good in overdrive. this pedal will be the ticket.
