I'm partial to the acoustics sound. I use it with an EVm 12 and a 15 and it takes care of small/medium gigs where we aren't using FOH with guitar and bass. My 136 is just the head divorced from it's very huge and heavy cabinet and speaker. It is in a case as the 140 and 150 bass heads were. I have a 140 as backup and an earlier 136 as well.
