Since DV Mark does not sell a footswitch for the amp but adds the option to use one, i bet they fallowed the standard operation found on most common footswitches. I guess any schematic related to any mainstream latch type footswitch would work. If the status of LED and the desired channel selection does not match, you can simply change polarity by re-soldering plus and negative the opposite way.I'm trying to build a single footswitch with LED for the DV mark little gh 250 to change the channels - does anyone have any idea how it should be wired?
By the way, Nick Robinson, since you are the only one on this thread who actually have the GH250 amp, what is your opinion about the amp? Is it any good? Could you please share your observations, also a little comparison with other amps you have/had would be quite informative to us since there is very limited talk about these new amps. Thanks in advance.
