Angelo Marruzzi (who made the well-known schematics)
I've seen two and they were in different cases... One appeared to be made by Sola/Colorsound, and the other could have been a custom one-off or DIY but it's hard to tell because there are so many similar unknown british pedals like that... Seen lots of obscure ones from over there, Italy too.
The one that seemed like it was DIY had all Italian components in it and had the same coat of arms from the orange amps on it, but I'm pretty sure they didn't make any pedals.
Probably these pedals were custom or DIY work using different cases, not real Orange products.
Mick Dines (Orange)
Orange did manufacture three guitar effect pedals during the 70’s: a Phaser, a Sustain and a Distortion pedal.
Needless to say, they were manufactured in small Orange die-cast boxes with a simple ‘in’ and ‘out’ and footswitch.
To the best of my knowledge we never produced a Treble/Bass Boost but I have seen the circuits you mention on the internet.
