The outstanding one for me is Trace amps. I’ve tried pretty much everything else, but I always go back to my trusty old TE heads and particularly the AH250 SMX.
Basses it would probably be Musicman. I love Fender, Status and Aria, but I’ve had lots of Musicman basses. I’ve never had a bad one and I’ve not been without one in the stable over the past 10 years.
EDIT - Oops forgot cabs. Barefaced. I’m a big fan of both the 12”s and 10”s. For power, weight and size, pound for pound they’re the best I’ve tried by a long way.
