Csnd Supa Tonebender

‘73 UK interpretation. The first clipping stage is removed which

changes the sound to a mix of Tonebender-meets-Fluff. Heavy!

Transistor pinout is reversed so flip them. There was an extra cap

between the third gain stage and the tone section, but it’ll sound

just the same without it. If you want a 100% clone look elsewhere.

Csnd Jumbo Tonebender

Based on the Supa, but the final gain recovery stage was removed giving

this much less gain and output level than its older brother. It has heavy

hints of BFP but has its own character. Great on bass. BOM as above but

changes as shown below.
