Need a cab, probably ti be installed, mostly, at a rehearsal space. So... 1) Ampeg PR212H, or... Trace Elliiot 1518? 2) Also, ever pair a 212 and a 15? Cinsidering the PR212H with an Ampeg PR15H... Simple really... the first question is my primary one. The second idea would be to use with an Acoustic 370 head, to run it at 4 ohms. The Ampeg cabs mentioned here are 8 ohm cabs... Appreciate your momentary consideration!
