GPM 45-1796 MKII, '23

GPM 45-1796 MKII, '23

From Metropolous:

"I went back to the input jack and started from scratch.  All of the quirks of the original JTM 45 serial # 1796 are faithfully retained in the GPM.  Including the hybrid LEAD/BASS tonestack with uses a 560pF capacitor where most JTM's have a 250pF. 

The authentic preamp feeds into my new emulation circuit, which captures and recreates the frequency response, clipping and harmonics of the original phase inverter and power amp.  This allows pure JTM 45 tone at any volume.

For optimal plexi cleans as well as early plexi overdrive, I included a 3 way "bright switch". 
Options are:  no bright cap, 100pF or 560pF.  Offering a range of plexi tones that even my original JTM 45 can't match."

SPECS:

  • Historically accurate "smallbox" headcab
  • aluminum chassis
  • gold front panel, white rear panel
  • approx 38 watts from a pair of KT66 output tubes
  • tube or solid state rectifier (switchable)
  • 3 way Bright Switch (NONE / 100pF / 560pF)
  • high quality pc board construction
  • Zero Loss FX loop
  • fantastic master volume

Very Good condition. -ON HOLD TF TOW 05/22
