Overdrive
Description
5 knobs, blue with yellow graphics, made in 1987. A smoother, lower gain version of the Real Tube. Same pcb as the 901 Real Tube. The primary difference from the 901 circuit are a few different resistor values in the drive section and a smaller Hi pot value. No true bypass. Early production was made in the USA throughout the 1980s and 1990s. A small number of those were made with gold colored tops and blue printing.
After Genz Benz bought Tube Works in the late 1990s a Taiwan made version with different knobs and graphics was produced throughout the 2000s.
