So this is the first brand new amp I've bought in a couple of decades..lol! Initially I ran the D.I. into a mixer and 5" powered monitors, I liked the sound pre-eq. Later I used it at worship rehearsal into a GK Backline 4x10 8ohm. Thru that cab it seemed to lack low end girth, i boosted the low end quite a bit and it was somewhat better. Tonight I'll run thru my Eden cabs that'll be primarily using, if I'm happy how that sounds I'll keep the amp, if not back it goes. Peace!
