"Your amp continues to inspire me every show. It’s incredible!"

James Pennebaker, Nashville, TN

"That's killer....normally I'm not a fan of EL84's because they compress too much....this doesn't really compress as much as normal or too much.

Joe Bonamassa

JOAT 20W Combo: "Love it. It's a big 20 watt. The cleans are great, different than all other amps. The tone shaping is great. I must say it's one of the most usable tone controls I have ever experienced. The tremolo is great. The amp can get some good break That is pure magic."

Haakon Lien, Hønefoss, Norway

"Hey Todd , I’ve been recording the amp all day and it sounds fucking fantastic !
Had to drop you a line to say thanks."
