Note, pictures shown here are of a similar Fat Jimmy amp, the Custom 20. The 20 Supreme version of this amp has no vibrato and includes a mid control and a master volume on the second channel. All other aspects of the 20 Supreme are visually identical to photos shown here.
THE 20 SUPREME IS THE NEWEST, LATEST AND GREATEST FAT JIMMY AMP. THE TONES THAT THIS AMP PRODUCES ARE SECOND TO NONE.
The Fat Jimmy 20 Supreme is closely based on the Fat Jimmy Custom 20, which has been called Fat Jimmy's answer to the Fender Deluxe Reverb. Like its sibling though, the 20 Supreme is NO Fender DR clone!!
The 20 Supreme, like the Custom 20 would be in the same class as a Deluxe Reverb as it delivers approximately 22 watts of all tube power into a single 12" speaker. More muscular than a Deluxe Reverb, the 20 Supreme provides more 'beef,' more clean sustain, more touch sensitivity, better note blossom, intuitive response, richer harmonic content, and creamier overdrive.
The 20 Supreme utilizes the same circuit as the Fat Jimmy Custom 20, but without the vibrato and with an added a mid control to the second channel, along with a master volume. These new controls, along with the "Jimmy' and preamp volume, allow you to really dial in the headroom and breakup point of the amp. You can get a lot more grit at lower volumes than with the Custom 20, but also the same amount of headroom.
The first channel is voiced with a tweed style preamp for a thicker, beefy, more aggressive channel with more midrange emphasis and slightly earlier breakup than the second classic channel. The second 'classic' channel delivers what is expected by the blackface player, but also borrows from the brownface era. This gives you a different treble response, allowing you a greater treble range than the standard blackface preamp. You can get both more AND less treble than your typical BF preamp. The ability to dial back treble is ideal for those players who find the blackface amps too bright. The Jimmy, reverb and vibrato controls work for both channels.
The single Fat Jimmy C1270 speaker sounds incredible paired with this circuit in this size cab. All of these aspects align to deliver an absolutely incredible little powerhouse of an amplifier!!
