External Expression Ernie
For those that want to experiment but don’t want to modify their unit or have a variety of volume pedals they like to use: the external expression ernie will turn your volume pedal into an expression pedal and back! just connect your volume pedal to the loop and the expression out jack to the pedal you’d like to express (TRS connection, for mono connections still use a TRS cable). in blue mode your volume pedal is a volume pedal, in Red mode your volume is true bypassed and it magically becomes an expression pedal.
please note: this will not work on a BUFFERED or ACTIVE volume pedal, passive (no power) only. a buffer can be built into the box for $20 more.
The approx build time for an External Expression Ernie switcher is 1 week
