I'm currently running my guitar into an AMT R2 preamp then a Mosvalve 500 watt poweramp. So my rig is completely solidstate. You know how people say some amps don't "open up" and start sounding good until you crank them? Well I have the opposite problem My bedroom sound is GREAT. Ideal to me but, once I start hitting stage volumes my sound goes downhill. The lows start to disappear, the highs start to get harsh, and that sweet crunchiness starts to get a little fuzzy. Why is this happening? Is it my poweramp? I try to compensate by rolling back my tone knob or turning down presence but, then my sound gets dull. How can I remedy this problem?
