The JOAT 20RT+ Amplifier

The JOAT 20RT+ Amplifier head with Reverb, Tremolo and Headroom Limit

Description

Jack Of All Tone/20 Watts/Reverb & Tremolo/Headroom Adjust. Now available with EL84 or 6V6 output stage.

The next generation RT: An additional drive stage is added in front of the power tubes. The added 12AU7 stage isn’t a “gain” stage per se but instead adds a moderate amount of drive current extension beyond the original “RT” design. This also enables a new HEADROOM adjust switch which limits output clipping level to about 70% of normal when activated.

Exceptionally rich plate like REVERB and ultra smooth TREMOLO. “HR” HEADROOM limits output clipping to about 15 watts when activated.  

 

Features
  • INPUT ONE: is optimized to a Single Coil pickup
  • INPUT TWO: to a Humbucker, but you can run whatever you want into either one.
  • BITE: selects upper range muscle at the first gain stage in 3 positions. 
  • HR: HEADROOM limits output clipping to about 15 watts when activated.
  • ATTITUDE: offers a useful variety of gain and EQ selections in five stepped rotary positions. 
  • LOW CUT: 6 position rotary selectable coupling network dials in the Low end sweet spot.
  • HIGH CUT: 6 position rotary selector controls a local feedback network. Instead of conventional preamp stage treble shunt control, the JOAT employs power amp treble compression.

This isn't a guy building his "brand new take on a Vox/Marshall/Fender" using a bunch of off-the-shelf parts shoved into a Mojo cab.
I heard the reverb compared to a plate or rackmount reverb while reading reviews of the amp prior to purchase, but wasn't putting too much stock in it. WOW. Those weren't exaggerations. With three knobs and a bright switch, you have the most adjustability of any amp reverb I've ever used.
