Four new circuits are releasing today, including something I’m really excited about: the Dinosaural Tube Bender. There are only 150 of these in existence and we were able to trace one of them. The tracing process is documented here if you’re interested in it!


Wyvern Silicon Drive PCBWyvern / Dinosaural Tube Bender

An exceptionally rare and unique drive pedal designed by Dan Coggins of Lovetone fame. This is a brand new trace, and while the circuit was released as a DIY kit by a magazine in 2004, the commercial version is pretty different.

Originally designed by BJFe before becoming the first BJFe-licensed Mad Professor circuit in 2007. A sort-of Tube Screamer with a lot of twists & turns along the way.
