From the vendor
Here’s a really simple, great beginner project!
The “transparent overdrive” circuit was one of those pedals that was the must have, mystical tone give a few years ago – which still commands a hefty price today.
It’s been compared to a KLON and a Timmy – the original uses fancy paper in oil caps…you don’t need them…don’t get suckered into that hype! The board is super small and has 8 components (including the pots!!). A really nice used as a mild overdrive or just a clean boost, then crank the gain and you’ll get a nice bluesy sound. You can also run it from 18V if you want more headroom and boost (just make sure your components are rated to deal with that voltage!
Controls:
• Gain
• Volume
Note: Remember to socket your transistor.
