Here's my Weber JTM45/Plexi thing, sitting atop a MusicMan 4-12 that I pulled from the local landfill about 10 years ago. The head has the JTM power section, with a JJ GZ-34 rectifier, and a plexi-ish pre-amp, with a few mods. Switchable .68uf cathode bypass cap on V2, switchable .0047uf bright cap on the bright channel and the Lar/Mar ppimv. It has NOS Tesla EL-34's, a Tungsgram in V1 and RFT's in V2 & V3 The cab is loaded with 2 WGS ET-65's and 2 V-30's. I re-covered it in Red Levant to match the head. New corners, side handles and casters were added as well.
