MI USA. Good condition with player wear. This is a rare DOD from this 80's series.
The 225 Master Switch was introduced in 1988, and was initially marketed as a useful addition to the then-new DOD PRC-6 pedal road case. The 225 was derived from DOD's FX30B Gate/Loop pedal, using the same circuitboard (but with many fewer components). The key differences between the 225 and the FX30B are the 225's obvious lack of control knobs and noise gate capability, and that the location of the OUT and SEND jacks are switched. We have only seen a handful of 225 Master Switch pedals, but it appears the 225 had been discontinued by late 1991.
