Inside every SWELL pedal

The G-Pro is the answer to requests from touring and session players alike for a mid-gain push-drive pedal from SWELL.

Single-coil, P-90 or humbucker, etc.–the PRO brings out the best in all of them delivering tight round lows, string-tone flavored mids and a clear open top end.

As with all SWELL drives the G-Pro has just the right amount of smooth natural tube-driven compression, rich complex overtones and is fundamentally transparent.

Footswitch select between Gain 1 and 2 for the just the right amount of drive for rhythm and solo playing.

The NEW Fat & Cut switches in addition to the Tone control allow you to shape your tone both easily and quickly.

And yes–the Pro remains dead-quiet even with the output level control maxed out!

Cranked amp tone and feel at any volume level delivered by Amp & Record outs.

On stage and in the studio the G-Pro delivers!
