Alrighty, so, I suppose I wasn't in a position where I really needed to get one of these, but I wanted to add as many features into my 7 string LP as possible. I had only heard a few soundclips of the afterburner prior to buying. The AB offers a variable 20db gainboost activated by a push/pull knob you can install in a vacant tone pot. The gain boost is flat, in the sense that it boos all frequencies across the spectrum, which makes it a bit less dynamic than an overdrive pedal. Activating the circuit on a clean channel will really put into perspective how much this thing boosts your signal. Over all, it does sound pretty dang good. It really saturates your sound and drives your amp. I think its an awesome alternative for someone who isn't into pedals. It's also way nice to have when you find yourself jamming through someone elses rig and don't have any pedals. I'll probably put one in all of my guitars eventually. Works with passive pickups too! Anybody else had a go around with this thing?
