The original piece of electronics that started it all! This is a controller which features the same specifications of the Fender® 6G15® reverb unit replacing the tubes with JFET transistor technology. This is not a digital effect.

Spring reverb technology has been well known for more than 50 years. One of the first reverb units available for electric guitars was the Fender® 6G15® standalone reverb, which has set the standard for generations of musicians. Still today, the unique sound of spring reverbs is very popular among guitarists.

A detailed description of the Fender® 6G15® reverb can be found on the SurfGuitar101 Wiki.


Basically, the tubes in the schematic are replaced with JFETS/MOSFETs and the output transformer with a current source. The circuit is all Class A and it is optimized for a tube-like harmonic content. It is using a standard 12V DC power supply adapter.


Is a vintage reverb unit true bypass? Changing the tone a little bit is part of the game here and we wanted to keep it so. We did not invent a new effect, our purpose is to allow everybody to enjoy that sound without carrying around a heavy and expensive instrument.

A question before buying: CAN I DO THIS?
You have to know your skills before approaching a DIY project. Although it is extremely simple to use out kit, you still need to have a basic knowledge of soldering and assembling. Please be aware that we absolutely cannot provide assistance on these fundamentals, so if you are not able to build it yourself or you don't have someone to do it for you, we strongly recommend to buy the SurfyBear Pedal instead.
