so, I know the MB212 is almost double the price of the other two amps, but I'm looking at all three of these. I have a bass with dual outputs on it, and I have a neck pickup that I send to a "low" amp. I have a 4x10/1x18 fridge cab I use, currently, but I'm looking to get into smaller cabs for portability reasons. I tested out a (used) GK MB212 that was in rough condition against a new GK MB115 today, and the 115 seemed to put out more bassy low end (which I liked). both seemed equally loud, but the MB115 seemed to fart out sort of early on with the bass and low mids boosted. I'm curious if anyone has any input with the volume and low end perspective between the MB115 and the MB212. another thing I'm thinking about is the TC Electronics BG250. it's an alternative to the MB115, I suppose. same price, seems to be close to the same sound. any word on if the BG250 will fart out early with the bass and low mids boosted? I tried searching to see if there was any similar threads, and I didn't come up with anything.
