Keytars Plexion pedal has three knobs that control Gain, Tone and Volume, as well as a toggle switch to flick between Bright and Normal sounds, and a true bypass footswitch control to finish. The toggle switch has two options of either Bright or Normal. Using the Bright channel allows you to enter into classic rock to late 80s and early 90s rock territory depending on just how much gain you wish to apply. To go that extra step further into creating blistering lead tones, just turn the gain up to full and hear that roaring sustain that we all know and love when you're really testing an amp to the limit The Normal channel is by no means average by any stretch of the imagination, just adjust the gain, tone and volume dials to get the desired output and you will be amazed by its rich, full-bodied output that sounds just as good clean as it doesn't heavily distorted.
