"Hey Greg,
The kit showed up this afternoon.  The chassis is gorgeous. The packaging is pretty slick. It is obvious you have put a lot of work, blood, love and expense into the design."

"Hey Greg,
I got the amp running. It sounds great! Chimey, musical, deep. I tested it through my boogie combo, and it was a blast!
Thanks for designing this thing. It has been a fun build project, and I am sure I will keep tinkering with it for a long time."

Introducing the Karma 20T
- Build your own boutique guitar amplifier!
  • Designed by a Grammy-nominated, award winning producer/engineer/mixer
  • Check out the complete online build manual at karma20tmanual.karmaguitaramps.com
  • 12-25 watts of glorious 6V6GT or 6L6GC power
  • Cathode-biased design - no need to bias the amp when changing tubes.
  • Two distinct preamp channels:
  • ​Channel 1 - Cascaded 12AY7 - beautifully touch sensitive with lots of grit - like a quieter, growling 2204.
  • Channel 2 - NOS 5879 pentode tube, loosely based on the first channel of the venerable Gibson GA-40 of the late 1950s.  Smooth, clear and slightly brighter than Channel 1, with an extended low-frequency range.  Great with pedals.
  • Massive Heyboer transformers and choke, custom made in the USA.  Way overbuilt - these should last forever!
  • Tube rectifier for warm and beautifully compressed tone when driving the amp.
  • Highest quality parts, sourced in the USA where possible.
  • Heavy gauge, custom made, powder coated and screened aluminum chassis.
  • Combination turret board and point-to-point construction
  • Tube complement: 12AY7, 12AX7 (x2), 5879, 5Y3, 6V6GT (x2) or 6L6GC (x2) with GZ34/5AR4 rectifier
  • Simple but effective single-knob Tone control with channel-independent circuitry
  • Phase inverter bias modulation Tremolo - deep and juicy!
  • In-rush current limiter start-up provides a "shock absorber" for power-on transients.
  • Enhanced Standby circuit helps preserve your valuable tubes by purposely running them at a low level when on standby.
  • 4, 8, 16 ohm Speaker outputs
  • Easily modded to suit your needs.
  • Optional custom designed head and speaker cabs - see our other listings.
  • Check out our website - KarmaGuitarAmps.com - for more photos, info, and sound examples.
  • Tubes not included but available upon request.
