Designed by Epic Amplification, the new SILVER PCB fits into our 22H/Custom 2.X platform of chassis/cabinet and transformer set. This PCB features the modifications to a famous rental amp from SIR #34 and #36 used on a number of 80s hard rock albums which set the standards for guitar tone.

Channel ONE: Plexi / Cap'n Crunch - The front panel switch option ($25) adds a great lower gain Plexi voice to your crunch channel. If you want to avoid the upcharge for the switch this can be hardwired in either position. Cap'n Crunch is #34 with its thick and heavy distorted rhythm tones.

  • Gain boost switch option +$19

Channel TWO: Silver Hammer - Silver Hammer brings those legendary higher gain tones of the SIR #36 rental amp made famous by players like George Lynch and Slash.

  • Gain boost switch option +$19


  • 4 12AX7 JJ preamp tubes. 22H has FIVE 12AX7 - upgrading to this PCB removes one tube which was used for the loop and is replaced with the SS loop below.
  • 20 watts from 2x EL84 JJ matched power tubes
  • Hand-soldered, thick (black) PCB with through hole construction. High-quality components throughout
  • Transparent pedal-friendly SS loop with internally adjustable level


  • Saturation switch - adds diode clipping +$19
  • Rear-mounted variable DEPTH control +$35
  • Many tolex and front baffle options +$50 Make sure to choose NONE to keep your existing cabinet. If you choose BLACK we are re-covering.
  • Knobs - choose any set of 8 +$8
  • Upgrade 4x 12AX7 at $60 for JJ, or $80 for EH or Sovtek

Optional switches are not labeled on the front. We can identify those positions in notes when the build is complete.

Assembled in Boise Idaho from US-made and imported parts. 

As always if you have something specific in mind or a question please email to info@jetcityamps.com 


Tube upgrades are available for those who have a preference of brand, as tubes can make a distinct difference in your amp's tone and performance. If you have something specific in mind let us know and we can quote you - likely somewhat higher than the in-stock options which we buy in quantity discount.
