Carl Martin Octa Switch MKIII

The Carl Martin Octa Switch MKIII Guitar Effect Looper is an 8 way guitar switching solution designed to bring out the best in all of your stompboxes whilst adding practicality to your stage show. It allows guitarists to link up to 8 effects pedals without any signal degradation and helps to avoid players tap dancing across their board to constantly access the sounds they are after whilst at the same time minimising cable clutter.

To set up the Octa-Switch MK3, plug up to eight pedals and amp(s) into the appropriate inputs/outputs on the back of the pedal. The pedals can be in any particular order you prefer or you can follow the general rule from 1-8 of compression, overdrive, and modulation. 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). In order for the pedals to work properly with the Octa-Switch MK3, all the pedals must be turned on.

There is a buffered or True Bypass (non-buffered) switch at the back of the Octa-switch which you select depending on the stage set-up or your personal preference. 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). Buffered bypass functionality is included to ‘beef’ up the signal if needed.

The Octa-Switch MK3 has stereo outputs as well as the 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 MK3 has nine switches, the eight are presets and the ninth is an effect Bypass, which will bypass the Octa-Switch MK3 to your un-affected amplifier sound. Please note if the Buffered Input is engaged at the back of the pedal, it will also be engaged in the bypass Mode on top of the pedal, as they work in conjunction with each other. Similarly, if the True Bypass Input is engaged at the back, the Bypass switch on top will switch to a True Bypass signal.
