Guitar Effects Processor


The GT-3 Guitar Effects Processor takes the professional-quality guitar effects and killer COSM-based preamp of the flagship GT-5 and places them in a sturdy, compact pedalboard with a surprisingly low price. With 32 onboard effects -- including new Auto Riff, Acoustic effects and a Pickup Simulator--the GT-3 opens the doors to a whole new world of guitar processing power.
