Gearank Recommendation

The Origin20C appeared on our recommended list for Tube Amps Under $500 from November 2019 until it was removed in April 2021 when it was no longer available for less than $500.


The Marshall Origin 20C is a modern take on early Marshall amps like the JTM-45 and the 1959SLP "Plexi".

As such it is a straightforward low to mid gain amp, with 3 ECC83 preamp tubes and 2 EL34 power tubes, driving a 10" Celestion V-Type speaker - all of which work together to reproduce the classic Marshall sound.

Inspired by multi-input classic amps, Marshall added a Tilt control that lets you select between the bright and normal input tone, and blend it to your preference.

Another modern feature of this amp is its built-in power attenuator, which lets you switch between 3 power settings, Low/Mid/High, adding to the overall viability of the amp, be it on a loud stage or for quiet practice.

For great vintage Marshall tone without the Vintage Marshall price, The Origin 20C is a great tonal palette worth exploring if you adore the Marshall "house sound".
