The JOAT 20RT Amplifier

Our Flagship 20 Watt Amplifier head with Reverb & Tremolo

Description

 The JOAT 20RT: Jack Of All Tone/20 Watts/Reverb & Tremolo.

The JOAT Series Amplifiers don’t have conventional Tone controls. IT’S ALL TONE, but you can take some away if you like. The JOAT couples signal in a more direct manner without the inherent loss of a traditional tone stack which is rarely touched anyway once you find the sweet spots. This entire circuit is one big sweet spot.
“My flagship 20 watt head was a long time in the making. Playing guitar is artful expression and so is building a great amp.  My amps represent the culmination of a long career of playing and looking for it – like we do. Finding certain elements in great amps and then pulling from a lifelong compilation of knowledge, hits, misses, success, frustration, screwing with every amp known to man, and eventually honing in on a circuit topology. 
It’s not “distortion” – it’s harmonic agreement. It’s not a swiss army knife of options – it’s really just an amp that doesn’t fight me when I’m looking for agreement. That’s what I’m looking for in an amplifier. Kind of like it knows where I’m trying to go by the way I touch the guitar.  Attending to fundamental circuit blocks sympathetic interaction is key in all of my amps. It’s simple but not easy to dial in. An amp that stays strong and clean where you want it to, and then as you progress that volume on up past noon and lean into it – – – a richer harmonic convergance comes into play.  The power supply, output tubes and output transformer – all saturating and compressing  sympathetically. That’s what I’m after”
Special sauce: Exceptionally rich plate like REVERB and sublime TREMOLO. That’s the JOAT RT series amplifiers.

“I am interested in building amplifiers with good reflexes. Amplifiers that respond to the way I touch the fingerboard, to subtle adjustments of the guitar controls. These are the kind of standards I hold to with my designs. Amplifiers that have personality just like instruments do.

When I plug in, it’s not just about how I want to hear the guitar. It’s about how I want to connect with the guitar - so I can connect with the music and sit right inside it. It’s very much about what happens between the fingerboard and the baffleboard. There is a dynamic relationship there and I think guitar players are looking for more agreement and less argument in that relationship.

You want to plug in, and the first thing that happens is your guitar says: “Thank You”. This is the amp that you plug into, and you don’t want to stop playing”.

“There is a certain level of sophistication at work here that sets this amplifier apart from the ordinary – now matter how you set the controls”.  Tone Quest Report
