This is a pre-owned pedal. 

All pre-owned pedals have been tested and are in proper working order. Each pedal is rated for condition on a scale of 1-5 (5=excellent condition/as new; no paint chips or scratches). The rating is for the pedal only. If it comes in the original box, that will be noted in the listing.

The condition of this pedal is rated 5/5.

Like its sister pedal, the Jetdrive, the GS3 has two channels that can be used independently or cascaded, with each one having a unique voice and gain structure. 

More flexibility is provided by a third footswitch that operates an overall bypass regardless of the on/off status of the channels. Each channel is capable of producing usefully different sounds.

Both function nicely as clean boosts and, while channel one features the milder overdrive and a rear-panel 'cut' knob that controls presence, channel two is higher gain and is voiced not unlike a Marshall 'Plexi'.

With two channels cascaded there's a huge palette of full-bodied overdrive available.
