FX Loop Muted

---

There is no sound when using loop

In my amps the FX loop is always in the signal path even if nothing is plugged into the send and return jacks.

If you get sound without the loop then the loop circuit is functioning properly.

Plug a guitar cable from the send to the return jacks. Do you still have sound?

• Yes there is sound when I jump the send to the return

• No there is no sound when I jump the send to the return
