Product description

The Groff Custom 20 is a custom, hand-wired guitar amplifier based on the highly acclaimed HiWatt amps of the early 70s. We’ve paired an accurate re-creation of the DR-103 preamp with a custom 6V6 based power amp, delivering classic, huge-sounding HiWatt tones in a very manageable platform.
• Solid state rectified with 22 watts of output
• Three inputs: Normal, Bright, and Link (Jumped)
• Effects Loop, Switchable Boost Stage, and a very useable Master Volume
• High headroom but easy to overdrive
• Perfect pedal platform
• Hand-wired, turret board construction


These amps are built to order.
