“the nano was a bit of a disappointment”
“We checked it alongside Muffs from 1973 and 1984 as well as a fairly newish one and, minor tonal variations aside, it did all that was asked of it. This size at this price gives nobody an excuse not to have a Big Muff underfoot.”
“It packs the beloved punch and delivers jaw-dropping performance no matter what.”
“I really like how it interacts with my reverb setup”
