Manual Octa-Switch

Ok, so you have eight effects pedals which you use regularly. You use various combinations of these pedals

in various songs, but you are not good at tap dancing...or you are just clumsy and have stepped on the ultra

tricked out-metalized-distortion pedal for the lead in your one ABBA cover. You have seen the digital effects

controllers they use on the big stages, and have secretly yearned for one, even though you may never make

the big stage? Enter Thomas Guldmann's Octa-switch. Your eight effects plug into the eight effects-loops on

the back of this unit (all true-bypass, impedance free gold relays so you can run any of your pedals, new and

old without problem), and then by turning on or off the numbered switches in each of eight DIP Bank switches,

you determine which effects you wish to use simultaneously in each Bank. There is a blue LED for every

effects loop used and for each Bank (so once you are programmed, when you step on Bank 6 you will see the

lights of all the effects you have assigned to Bank 6 and the Bank 6 LED). Once you have each Bank

programmed, we recommend placing a piece of scotch or electrical tape over each DIP (....just to protect the

switch from damage or floods....like beer). There is a buffered (or not....switchable) Mono input and a stereo

Output, and the unit is powered by dual 9v batteries, or by a regulated power supply.

Then by turning on or off the numbered switches in each of eight DIP Bank

switches, you determine which effects you wish to use simultaneously in

each Bank. There is a blue LED for every effects loop used and for each

Bank (so once you are programmed, when you step on Bank 6 you will see

the lights of all the effects you have assigned to Bank 6 and the Bank 6

LED).

Please note, the DIP switches are slide type, NOT push down. They are

easily operated with a small screwdriver, a pen, or a very very small finger.

There is a buffered (or not....switchable) Mono input

On large stages when running long connected cables, there is a definite drop

in the high end of your guitar sound (more or less depending on the input

impedance of your amplifier). The solution according to Thomas was once

again 'simple'. He built in a buffer circuit at the input, so the user can choose

between 100% true bypass, or buffered bypass to 'beef' up the signal.

Loop 8 offer a mono send and a stereo return on a stereo jack plug,

with left at the jack tip and right at the jack ring.

You use various combinations of these pedals in various songs, but you are not good at tap dancing…or you are just clumsy and have stepped on the ultra tricked out-metalized-distortion pedal for the lead in your one ABBA cover.
Page 2 The Octaswitch has stereo outputs, and a stereo return on Loop 8 (this is a stereo jack with tip-left and ring-right). Since stereo effects like choruses are placed at the end of your effects-chain, we would typically insert them in Loop 8. The Octa-Switch has nine switches, the eight are presets and the ninth is a true bypass switch, which bypass the unit for clean sound.
