UBE Screamer PCB v1.1

This is the second version of the UBE Screamer board. This version fixes a mistake with the reverse polarity diode. I’m calling this ready for public consumption and will add it to the OSH Park projects pages soon.

The enclosure is grounded through the jacks. The bottom cover though doesn’t make an electrical connection to the main enclosure body due to the powder coat. I used a drill bit to remove the powder coat inside the count sink recess, this allows the screw to make contact with the back cover for full shielding.

UBE Screamer by RunOffGroove

This UBE Screamer by RunOffGroove.com is a unique twist on the venerable Ibanez Tube Screamer TS-808. It replaces the op-amps and transistor stages with a single hex inverter using an inverter in place of each op-amp and transistor. This has a great sound that stands up to all of the other overdrives. Read more about it over at RunOffGroove.com

Well worth the effort, build it yourself! I’ve created a public project at OSH Park. Order boards and follow the build docs.
