At the upper right is the main In from guitar and Out to amp jacks. The switch bypasses the entire pedal board and turns off the main LED. I've found this feature essential for testing/troubleshooting. The whole point of this is that ALL KINDS OF THINGS affect your tone even though they theoretically shouldn't. The only way to know for sure is to be able to switch various components completely out of the signal chain. Also, some things can have their POWER chained together and some can't. Some very odd things behave differently depending on if they are chained to certain other things with BOTH power and signal.


Not anymore!


There is a dedicated tuner out for a tuner to live in the top right corner. Can also plug guitar into tuner and tuner into main In, to use tuner as buffer.

For the bottom row of switches, the right-most switch and pair of jacks is just an on/off switch. For single 1/4" switching functions such as Acoustic 165 reverb, Headbone amp switch, Fabamp channel switching etc. Just two 1/4" jacks, both either open or closed with the one switch, red LED lights up if closed.

The next SEVEN switches and corresponding pair of I/O jacks and green LEDs are your basic loops.

The rightmost two switches and I/O jacks and yellow LEDs are for the amp's effects loop. The effects loop cables come from the amp and plug into the two top leftmost jacks on the board. You can also jumper the main Out into the effects loop input, plug the main output cable to the amp into the effects loop out, then the whole board is just a normal series of NINE loops.
