A long-standing goal of mine has been to successfully incorporate a great sounding spring reverb into a classic 50s Tweed circuit, without taking anything away from the core tone.

Taking the lessons learned from the development of the reverb circuit found in the Aynsley Lister Signature amplifier, I designed a new circuit from the ground up, this time using a 12AT7 dual-triode valve as both driver and recovery.

 

The reverb effect compliments the core tone of the amplifier, without becoming splashy or intrusive. Vast, rich, and spacious reverberations are on offer from a conveniently located dial control, found on the main control panel for easy access and adjustment.

The Americana and Americana LP models produce 20w and 12w respectively, with a 1/2 power switch allowing the user to drop down to 10w and 6w
