When you plug in, it’s not just about how you hear your guitar. It’s about how you connect with your instrument – so you can connect with the music and get right inside it. I build amplifiers with superior reflexes – amplifiers that respond to the way you touch the fingerboard and to subtle adjustment of your guitar controls. These are the kind of standards I hold to with my designs. Amplifiers that have personality just like instruments do.
It’s very much about what happens between the fingerboard and baffleboard. There is a dynamic relationship between the two, and I think guitar players are looking for more agreement and less argument in that relationship. Call it what you want: tone, response or dynamics. What really matters when you plug in is that you truly make that connection.
From aesthetics to chassis layout; The JOAT series offers a truly original approach to vacuum tube guitar amplification. For starters, there is no tone stack which also means there is no loss that comes with a conventional tone stack. The JOAT approach is to tailor the first stage gain and response characteristic via the “ATTITUDE” rotary selector along with the simple but effective “BITE” switch.
From there we tailor the low frequency content via the “LOW CUT” rotary selector. Instead of a conventional treble pot, the “HIGH CUT” rotary selector employs a unique and effective local AC feedback network directly across the output tube plates, offering six levels of high frequency compression/filtering.
The REVERB is unlike any other. Two tanks are employed, driven by a power pentode for massive headroom, carefully buffered at both ends so as not to load the dry signal at all. The sound of this verb is more akin to a plate than a spring with DRIVE, TONE, LEVEL and PULL BRIGHT controls. TREMOLO goes from swamp to full stutter with ultra stable wide ranging SPEED and DEPTH controls.
REAR PANEL: IEC AC Mains Connector, Mains & High Voltage Fuses, Foot Switch Jack, Reverb Tank Connections, 4-8-16 ohm Output Load Selector, Main & Extra Speaker Jacks.
The JOAT is built on a roomy custom machined powder coated heavy duty aluminum chassis. Components: mil spec rotary selectors and pots, aircraft grade isolation mounts for the first stage 6AU6 pentode and for the dual Reverb tank design, custom spec transformers by Magnetic Components, Inc. and Mercury Magnetics. The chassis is fully hand wired with 19 str Teflon wire and stainless steel hardware is used throughout. With a painstaking process of selecting each component for optimum performance – the JOAT series amplifier delivers from Fingerboard to Baffleboard.
