Like a lot of us here we’ve been through many combinations of amps and cabs, some work well and others not so well for the sound we want, the setup I’ve had for a while I really like and I can’t see me changing it any time soon, it’s the Ampeg V4B with a big baby gen 3, my 71 precision with really worn in flats sounds lovely through it, it didn’t seem to match well with my markbass 15 or Ashdown 15, I also use an Ampeg PF50T which is ok but doesn’t seem in the same league as the V4
