5E7 Tweed "Bandmaster" Amp




The second amplifier I built was a 5F4 Super. I kept it for about a year, then sold it. It wasn't long before I regretted that, and when the chance came to buy the amp back I didn't hesitate. It was good to have it back home.

Now I've taken that 5F4 chassis, made the necessary circuit changes, and housed it in a 3x10 cabinet. The result is a 5E7 Bandmaster, a full, lush-sounding amp with a clear, powerful voice that sings when driven hard.
