The Carl Martin PlexiTone, now with a DC input, no more AC cord. As the name might indicate it's an unusually high gain three step rocket of an overdrive. The PlexiTone offers two step overdrive, the crunch channel and the high gain channel, on top of that it gives you an up to 20dB clean boost channel. The crunch channel goes from subtle overdrive to hard rock gain stage, the high gain channel goes from rock gain stages to absolutely meltdown, with loads of gain and low end, and all in a tone that brings the memory back to the early 80's high gain guitar hero's. Can be used with any 9V DC 200mA power supply, center negative. No battery operation.
