UBE Screamer 4069

UBE Screamer 4069

This is a version of the UBE Screamer using the 4069 in place of the 4049. Essentially these chips are the same. They both contain 6 inverters. The 4049 is a 16 pin DIP while the 4069 is a 14 pin DIP. Electrically the should the same but the pin arrangement is different.

The original circuit from RunOffGroove.com is a very interest evolution of the Ibanez Tube Screamer TS-808. RunOffGroove has an article describing how to make an adapter that adapts a 4069 to a 4049.

I decided to just make another PCB since I had already created a PCB for the original 4049 circuit. The adapter would work but ordering some PCBs from PCBWay.com costs about $25 for 10 boards which worth the time spent hacking a solution. And, the boards are well made and reliable!
