I’ve wondered this as well. Small lunchbox through a good power amp to create a similar sound as the big boy. Or is there something missing. I have personally found that the real head has something bigger than the pre- plus power amps. Maybe I cannot dial in or need a eq somewhere in the mix. I’m not an expert on how to set up but when I feel it’s right I stop tinkering then move. Problem for me is when I add another tone changer (boost, drive, modulator… it changes everything). Let alone a different room when gigging …. Wtf happened to my sound? Maybe just put earplugs in and wing it next time. “tonal rawdawg”
