I have a few amps, I marked GenzBenz, because I use it the most. One rehearshal a week, one gig a week.
Ampeg SVP + Poweramp and a
Peavey TMax I use not that often. Two rehearshal a month, two gigs a month.
Ibanez Promethean 5110 daily use for practising. I use it in the studio and for bar gigs.
I have a Markbass LM II I use seldom, only if I go "ultralight" on bigger stages or as backup - amp.
I have a Marshall MB 4410 I use seldom for playing it by myself, but I use it for giving lessons. My students play with that amp. It really sounds fine. No flaming about the Marshall MB-Series! I played that heavy mofo half a year because my beloved SWR Redhead went up in smoke, and there was no other amp available in a short time. Played the MB 4410 until I had a new stack together.
