SILVER. New for 2022. Hot-rodded Plexi with a wide range of gain settings.

20 watts from 2x EL84

Please allow approximately FOUR weeks from order to delivery. We build these amps one at a time.

Designed by Epic Amplification, the new SILVER PCB fits into our 22H/Custom 2.X platform of chassis/cabinet and transformer set. This amp 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 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 

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


  • 4 12AX7 JJ preamp tubes
  • 20 watts from 2x EL84 JJ matched power tubes
  • Hand-soldered, thick (black) PCB with through hole construction. High-quality components throughout
  • Heavy, custom-wound Jet City power and output transformers
  • Transparent pedal-friendly SS loop with internally adjustable level


  • Saturation switch - adds diode clipping
  • Rear-mounted variable DEPTH control
  • Front-panel channel switching with Overdrive indicator LED
  • Upgrade to Heyboer or Mercury US-made output transformers.
  • Acrylic control panel overlay color
  • Many tolex and front baffle options at no additional cost
  • Oversized Offset cabinet +$30 

Because we use the same acrylic overlays for all amps, 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. Each amp is built one at a time and hand-serialized. 

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.
