This is my build of the legendary Eau Claire Thunder, my favorite muff style fuzz of all time. This was the holy grail for me as an early pedal nerd. I thought I'd put some together now that they're out of production so you too can experience this ultimate fuzz. I'll let our old pal Aen explain it.


"The Dwarfcraft Eau Claire Thunder is the result of my wish to rectify a few issues I’ve had with other muff-style fuzz boxes, notably a mid scoop.


But Old Pal Aen, some times I need to scoop teh midz for my metal tonez!


While I can’t say that I ever find that useful, ECT will do that as well. When stomping on the “BYPASS” switch, you will be in familiar fuzzbox territory. Volume, Tone, and Distortion are all active, as well as the “TIMEWARP” toggle, which flips between the traditional hi-fi type sound and a more blunted, ummm, stoner-rocky type sound.


“TONEBLAST” bypasses the tone control, giving you more mids and a bunch more volume. At any time, you can tap the “feedback” stomper to trigger a momentary integrated feedback loop, because I like noise.

“Trim” allows you to roll back your input signal, in case of muddiness caused by hotter pickups."


T - Tone
V - Volume!
Top middle - Feedback tune, engaged by the ! footswitch
I - Input trim
D - Distortion


Right footswitch - On/off
! - momentary feedback and noise
Left footswitch - Toneblast!


1-3 week lead time but much closer to 1.


Knobs may be different on your build, contact me for specifics.
