Tim Felton

A third iteration unit was used for The Noise Made by People, as mentioned by Ghost Effects in this December 14, 2012 Harmony Central forum reply. It became the basis of Ghost Effects’ Silicon Pep Box (pictured together), as stated in the reply and on the official product page.

The one i do is the later large case version, silicon, and a slightly different circuit than the germanium version.

I traced the circuit from an original unit that I borrowed from Tim Felton of Broadcast/Seeland, the actual pedal is all over the 1st Broadcast album apparently.

I borrowed a very rare original unit from Tim Felton (Broadcast/Seeland) to confirm the circuit and the component values for this pedal.
