MISC: Boss FV500 Modification
The LF has the ability when you have an Expr. Pedal with Toe Switch
to program that Toe-Switch.
See here how to do that.
I have a Boss FV-500H which I like very much but unfortunally it hasn't a Toe Switch.
So I modded it myself. I build a Switch in it and connected it in place of the Tuner-out jack.
You have to use a momentary switch and connect it this way to let it work.
Here some pics of my work in progress :)
