I just got an acme b4 three weeks ago and hated it!!! I loved the low end but hated everything else. I just had a gig this weekend and loved it. I was doing way too much eqing on the preamp level. I had my prescence on my sansamp way to high and I ended up cutting a little bass. I'm still playing around with the mid and high attenuetors on the cabinet. It's really weird to be really happy with my sound and to be able to hear myself on stage. Another happy acme customer!!!
