So glad to finally be writing this. Its been a month in the works, but ive finally gotten my hands on this perfectly conditioned Mesa Boogie F-50, my very first. And it has to be said, the cleans are amazing on this amp. Still learning to dial in the drive channel -- it sounds good, or can sound really good, but it's very apparent that it needs volume to really breathe life into it, so a bottom-gain-bluesy-crunch is where it lives right now. But man...this amp really can sound like A LOT of things, shockingly versatile.
