Custom 20


The Fat Jimmy Custom 20 delivers approximately 22w of all tube power into a single 12″ speaker.  The Custom 20 has been called Fat Jimmy’s answer to the Deluxe Reverb – but once again, this is NO Fender clone!!  The Custom 20 has been described as a more ‘muscular’ amp in the Deluxe Reverb class, or a DR on steroids…  You get more muscle, more ‘beef’, more clean sustain, more touch sensitivity, better note blossom, intuitive response, richer harmonic content, creamier overdrive, etc etc etc…

The Custom 20 can give you everything you might expect from a Deluxe Reverb, and then some.  Greg Loiacono (The Mother Hips, The Sensations, Chris Robinson’s Green Leaf Rustlers) picked up a Custom 20 for use with some smaller projects, and then ended up replacing his 1964 Super Reverb with the Custom 20 in the Mother Hips!!  We were both pleasantly surprised by this little powerhouse’s ability to fill those shoes…

Two channels give the player two different voice options. Channel Two is a standard Fat Jimmy style preamp while Channel one is a classic ‘tweed’ style preamp with a thicker, beefier voice, more midrange emphasis and slightly earlier breakup.

The single Fat Jimmy C1270 speaker sounds incredible paired with this circuit in this size cab…
