Telos Insert Loop
To allow you to control your signal path, we have put an Insert Loop between the buffer/boost stage of the Telos and the input of the Drive stage.
Connect any other effects you like between them using this insert loop.
The Return jack sleeve
connection is not connected to signal ground in normal operation.
This prevents ground loops when using the second stage as a loop, and
prevents the cable in the loop from acting as an antenna for RFI and noise.
However, you may find that you either lose signal completely or there is a lot of noise when you activate the loop. This will generally be an indication that you are using a bad cable, or one where the ground has been disconnected. Replace or repair the cable and retest.
In the very unlikely event you have noise or a loss of signal when using
the loop, and you have tested the cables involved and found them to be
working well, then turn the mini-slider switch on the bottom of the PCB
(internally accessible) from LIFT to GND.
