Hi there, Hi there, In our band, my sons play the guitars. One plays an Electromatic Pro-Jet with Bigsby, I play slap bass and occasionally my G5129. My other son plays a Mexican Fender Telecaster through a Fender Bassman 59 reissue amp. We've yet to use the amp at a gig, but he's worried about break-up at higher volumes. I feel sure that it's down to settings. The amp and its valves are in superb condition. He's looking for a really clean 50's Rockabilly sound. How would you guys suggest he sets the volume and tone contols and which channel should he use on the amp? Also, which pick-up should he use on the Tele and how should he set the guitar's tone and volume controls. Thanks in advance.
