Well like I said HM-2 is probably the best bass fuzz I've ever played. Not entirely sure but that V4-B would be from the 70's. Ampeg didn't make V series amps after MTI bought them from Magnavox in the 80s. But a V4-B would be my choice over either Sunn. It'll probably need some work. But those amps just roar, they're loud, distortion machines. Put a drive pedal in front and one could say that it might be... gnarly. I miss the tone of my late '70s master volume modded V-4B when I'd run it into my 8x10 with my Bass-Drive in front so much distortion and so much loud.
