Carl Martin Duel Injection Guitar Distortion Effects Pedal (Open Box)

The Carl Martin Octa-switch MK3. 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). The Octa-switch MK3 has incorporated a couple new features as well! The ninth switch on the left side of the case is a BYPASS Switch….this allows you to completely bypass all eight pedals and enjoy only the unaffected sound of your amplifier. There are also two External Switching jacks which allow you to use two amplifiers and/or switch channels on those amps. Once you have all the Banks programmed, we recommend placing a piece of scotch or electrical tape over each DIP (….just to protect the switch from accidental switching, 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…like the Power Jack or the Pro Power (both by Carl Martin).
