Re: Custom Echoplex switching pedals...any interest?
I haven't tried that one. Does it have LED's? My experience is that the
boxes w/ LED's won't work w/ the Echoplexi. Has anyone successfully used
a switcher w/ LED's?
Having LED's and one-button switching (for A/B/C) is my motivation for
having a new one made.
