The Carl Martin Combinator 2 was designed and developed in response to many requests from guitar players who use lots of effects pedals, but are frustrated by having to press several footswitches in order to turn multiple pedals on and off.
The Combinator 2 is a non-midi programmable effects switching system that handles up to eight pedals. Each pedal is connected to one of eight individual effects loops (two with stereo returns), and then assigned to one or more of 18 groups. Pushing the program switch for a group simultaneously engages all of the pedals assigned to it. So if, say, you have a fuzz, a wah, and a chorus assigned to program switch 1, pressing that switch will turn them all on or off.
The Combinator 2 features 18 programs,- tuner output,- master mute,- three external switches on separate jack output's.
Programming is a snap. Just select bank and press one of the program buttons, press the soft buttons corresponding to the pedals you want to include, press store, and you're done.
The Combinator 2 also features a power supply, providing eight individual 9-volt taps, one for each pedal.
