I just got a second hand Walk and Im intrigued, first I imagined that the momentary output should give me a hi voltage when I press my switch pedal, but its the opposite, its always hi until I press, I tried with two different pedals…
Second thing, it does not reach 8 volts as described in the manual, it reaches 7 (at the M).
Thirdly, the others dont get to 5 as I expected but to 4volts.
So, is that exactly how your Walks are outputting?
cheers,
Chris
