The JOAT 45RT offers a major kick in drive and output power compared to its lower powered 20- and 30- watt brethren. The 45RT mirrors the front end preamp and tonal shaping of the 20 and 30RT models with a few minor tweaks to accommodate an additional driver stage and substantial increase in output power. The JOAT 45RT may be configured with a pair of EL34s (stock) or 6L6/KT66 type power tubes with a simple bias adjustment. That along with the EL34/KT66/6L6 type output stage offers not just more power but a bolder character - for those who just need more beef on the bone than a 20 or 30 watt amp can provide.

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.

It's all tone - but you can take some away if you like:

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.
Includes: Reverb/Tremolo footswitch, hospital grade IEC AC Cable, custom fit padded canvas cover.
