Another classic that needs no introduction. But if you’ve ever wanted to mod the living daylights out of a Tube Screamer, this is a versatile PCB that fits in a 1590B.
There are two switches available: one for clipping diodes (with enough pads available for any diode combination you can dream of and “comp cut”/diode lift in the middle), and one that can be used for one of three other mods using jumpers:
- Fat mod (with three different settings) – read more at AMZ
- Brightness mod (also with three different settings)
- “Flat Mids” mod (from the Fulltone® Fulldrive 2)
With the right combination of part values and mods, you can build exact replicas of dozens of Tube Screamer-derived circuits, such as the following:
- Fulltone® Fulldrive 2 (single channel)
- Fulltone® RTO
- Lovepedal Eternity
- Landgraff Dynamic Overdrive
- Clay Jones Overdrive
Component lists are provided for a select few in the build document, but the Tube Screamer is a very inspirational circuit to say the least and there are many more out there.
