The "Classic" harks back to the late 60's and early 70's era of classic british amplification.
The "Classic" is a low to medium drive pedal that can be used to give your amp a "front end kick" or use it on its own for that "cranked amp" sound at any volume. If you are looking for that "non-master plexi" sound, then look no further.
The "Classic" has two modes, the first mode is a standard "master volume" type grind, the second mode adds more drive. The "Mid" and "Top" controls, allow you to match the tone of the pedal to your clean sound, or use them to "scoop" the mids.
This pedal sounds exactly as it looks. One Classic owner (a vintage plexi owner) said: "the G2D Classic is as near to the real thing as you can get."
As with most boutique pedal manufacturers, each pedal is hand-built and individually tested to ensure that each pedal preserves the guitars natural tone.
