[0.1″ pitch stripboard] D*A*M – Red Rooster RR-09


Yo! Here’s D*A*M take on Dallas Rangemaster – Red Rooster!

It’s classic treble booster circuit with added capacitor input blend and trimpot in place of 3k9 resistor on transistor emitter for better bias.

First roosters where made with excellent NPN germanium transistor CV7112 (military specs OC140). Later NPN units sports OC140 or OC139. Most recent PNP versions are equipped with many different transistor types – OC71, OC72, OC42, OC45, Magnatec AC128, CV7355 and CV7004.

Usually low leakage transistors in 70-100hfe gain bucket are recomended, but You can try other transistor types or specs – trust Your ears, not eyes 🙂


Due to D*A*M counterfeit pedals that recently appeared on the marked all D*A*M straight layouts will be removed from turretboard.org and will be replaced soon with our own works and interpretations.
