Terminal Device

Project overview:

Terminal Device is a highly modified Shin-Ei Companion Fuzz, based on the Earthquaker Devices Terminal Fuzz. The unique buzzy sound of the original pedal was awesome, but the modifications make this design go three steps further: the addition of a pot at input that regulates the amount of signal being fed to the circuit, a controllable tone stack, and an output gain stage after the volume control to get the fuzz above unity volume.

Introduction

Terminal Device is inspired by the Earthquaker Devices Terminal Fuzz, a highly modified Shin-Ei Companion Fuzz. This board offers both the unique buzzy sound of an old JAX fuzz and modern features that allow more in the way of control.

The 60s and 70s were the golden time for many quite distinctive fuzzes, and I’m not talking only about big names such as Fuzz Face and Tone Bende. If you dig a little, you will find that there were many unique gems, now discontinued.

Terminal Device is based on one of those rare pedals. The exceptional buzzy sound of the original board is fantastic. Still, the modifications make this design go three steps further by adding a pot at input that regulates the amount of signal being fed to the circuit, a controllable tone stack, and an output gain stage after the volume control to get the fuzz above unity volume.
