I have software, modelers and tube amps, also have owned Weber Mass etc. Actually I get the best results at low volume if I put my tube amps on like 0.2 and boost them with a nice pedal, e.g. the RC Booster or the Fulltone OCD.
I can set my basic preamp tones at low volume at home and when I rehearse/gig use the same setup and usually just take down a bit on gain, bass and presence.
