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. - Chris >have you tried Whirlwind A/B box? >as of A/B/C i use [for different purposes than yours] 2 A/B >A goes out to A >B/B is your B >B/A is C >sandro >---------- >>From: Chris Chovit <cho@newdream.net> >>To: Loopers-Delight@annihilist.com >>Subject: Custom Echoplex switching pedals...any interest? >>Date: Sat, Mar 20, 1999, 2:44 PM >> > >> Fellow loopers, >> >> I am currently working with a pedal-builder to come up with A/B and >A/B/C >> boxes, to switch the Echoplex DP footpedal between multiple echoplexi. >> Here is the problem I have with the A/B boxes currently available: >> >> 1.
