Embedded Files
Vintage style tube driven spring reverb based on GA15 circuit by Fender. This effects addtionally have a on/off switch on the control panel. This true spring reverb produce the iconic surf-rock sound.
Using footswitch reverb effect can be tuned on/off and to avoid introducing additional noise - picked up by a long pedal switch cable noise - footswitch is acting before reverb tank, thus it gets blocked.
