I have a DSL100H, and would like to replace the footswitch with one that has LED's so I can tell what setting I am on with my back to the amp. Can I use a standard externally powered 2 button switch with a TRS cable?
Hello Andrew,
Regarding your question, unfortunately the switching circuit within the DSL cannot power a LED within a footswitch. You would need to use as you have suggested an external supply such as a battery to power the LEDS but the voltage must not be allowed to get to the socket in the DSL as this could damage the internal circuitary.
