Carl Martin OctaSwitch MK2

Thomas Guldmann Octa-switch II is an advanced effects controller for guitar and bass pedals. It has eight effects loops with true bypass and impedance freedom, allowing you to use both old and new pedals without any problems. Each effects loop has its own LED that shows when it is active.

With eight DIP bank buttons, you can program which effects you want to use simultaneously in eight different configurations (Banks). Each bank can contain any combination of the eight effect loops. A blue LED shows which bank is active, as well as which effects are connected to that bank.

An additional feature is the Bypass button, which completely turns off all eight pedals and sends the sound directly to the amplifier. The unit also has two external switching outputs to control two amplifiers or channel switches.

The Octa-switch II is equipped with a buffered (or switchable) mono input and a stereo output. It is powered by two 9V batteries or a regulated power supply, such as Carl Martin's Big John or Pro Power.
