*Soundgas Type 636 (Grampian) Spring Reverb secret The tremolo can be subtle

The tremolo can be subtle and shimmery or full-on throbbing depending on where the depth control is set

It overdrives wonderfully and has a sound of its own

and you should read Tony's Gurus 1959 blog post on how he went from "yet another overdrive pedal" to it becoming an absolute essential for him that has had him playing more guitar than he has for years

Serviced and working but has minor issues

Excellent example of the beautiful Swiss “secret agent” recorder
