GUITAR: What's everyone's favorite new sound or toy?

TOMMY: I used a '59 Precision bass for the album. This record was a big turning point for me because Ted and our engineer got me to play with an extremely light touch with my right hand. I was hitting the strings harder with my left hand than my right, which was totally foreign. In this band I'm used to grinding my fingers into the strings. But each headphone had eight different pots for mixing, so I was able to put my bass way up in the mix, which meant I could just play super light and get the actual tone of the instrument. Though I didn't wind up using it for my tone, the Tom Scholz Bass Rockman has been an integral part of my writing and practicing for the last year. That thing is amazing.

JOE: All the demos were made with the Rockman; it's the best bass sound you could possibly get.
