so far -- the mesa d180 is the best i've heard for an all in one amp, great for bass and guitar. too loud though for guitar! to get it to sound its best it wants to be cranked, but that's blowing out the neighbors' windows. sold my plexi, and my hughes n kettner triamp after getting the d180. also sold my 400+. and my 300t. must say though that fliptop tone is beautiful. stunningly so, when heard for the first time. love to own one someday.
