And then there’s always the problem of how to control a pedal rack and various midi triggered effects. We have been busy analyzing the entire signal chain and producing various devices that correct many problems, as well as designing others that make using effects easier.From buffers to boost and keep the entire signal clean to midi mixers for the ultimate in effects flexibility, we can help you get the most out of your guitar amplification system.
