Is there any danger to an amp if one keeps the volume at very low levels 98% of the time (like 1-2)? (City apartment dweller.) Looking specifically at a GK Fusion head which has a tube-preamp and solid state power. I don't have immediate plans to gig, but am tired of playing only thru headphones after selling my SVT-7 a while ago (when I stopped gigging for a variety job reasons at the time). I'd rather buy once and get the big one in the event there's a reason to need the headroom, and I really like the tone of that GK head, but if the thing very rarely gets above low volume ... is that bad for the amp? Thanks!
