Ness’ main amp—stage or studio—is a 1967 Fender Bassman modded by Divided by 13’s Fred Taccone. Ness on his modded Bassman: “I don’t exactly know what he does to my amps, but I know that I look for a hotter, more overdriven tone at a lower volume. To get a great, rockin’ tone with most older amps, you need to push the amp and its power tubes. I was just looking for a way to heat ’em up at a lower volume so I wasn’t blown off the stage.”
