There is one overdrive circuit to this day that has been among the most talked about, the most sought after, and the most mythical of them all. Its that legendary tone that every guitarist dreams of. Brian Wampler captured that magic with his original Tumnus circuit, and it has since graced the pedalboards of thousands of players around the world.  The Tumnus has withstood the test of time and held its own in countless pedal shootouts, often coming out on top even against the original Klon pedal.


The allure of that original overdrive had a lot to do with a very specific secret” germanium diode, dubbed unobtanium” by the original creator, Bill Finnegan. It was said that these diodes were the heartbeat of the coveted tone, but they had run out long ago.  Despite this Wampler fans have been asking Brian to create a Tumnus using the exact vintage diode from the original.  


After a massive hunt Brian found a small stash of these elusive diodes and used them to create a limited-edition run of pedals - the Germanium Tumnus.  This pedal will satisfy both the pedal connoisseur and those seeking a new workhorse on their board.  The Germanium Tumnus retains all the usability of its golden sibling, but introduces an extra level of aggression, an Alien Silver” finish, and premium red anodized knobs.


The Germanium Tumnuss streamlined 3 control knobs (Volume, Gain, and Treble) allow you to quickly dial in your tones.  Set the gain around 9 oclock for a beautiful smooth overdriven boost and at noon for a fuller voiced, meaty drive. Turn the gain all the way up for a brutal, yet creamy overdriven tone. 


The Germanium Tumnus is a versatile addition to any pedal board. Stack it with another pedal to help push or shape the total amount of gain, use it as a standalone overdrive, or as a slightly dirty boost to push the front end of your amp over the edge. Just like the original Klon, this pedal is not true bypass”. 


This edition is steeped in a level of exclusivity with a tone thats set to become legendary. This stash of secret diodes” is limited, giving you a rare opportunity to own a piece of tone shaping history.  But once theyre gone, they’re gone and this pedal will be discontinued.
