From the post
A super rare pedal from the UK from 75-77. When they come up for sale they go for stupid amounts of money, >$700. The only information I could find about it.
This interesting pedal is Top Gear’s most dynamic, and combines both their Fuzz and Treble Boost circuitry into one versatile effect. Even though the pedal is capable of producing an incredibly large palette from which to choose, it is quite accessible, and sounds really good with any combination of control settings. Earlier Top Gear pedals are likened to concurrent better known fuzz pedals, and often draw inspiration from such simple circuitry, however, this circuit is completely unique to the Fuzz Sustain, and while it is similar to other late-’70s Colorsound and Eurotec models, there are significant differences. UK-made Top Gear pedals are inherently rare, and rarely are they available.
There was a request to trace it and create a layout.
