The Classic harks back to the late 60's and early 70's era of british amplification. If you are looking for the "non-master plexi" at any volume then look no further. The Classic sounds like your amp is cranked at any volume.
The Classic is a medium drive pedal which sounds great on its own or can be used to give your amp a front end kick. It has two modes the first is a standard master volume type grind, the second mode adds a little more drive, with a Mid and Top control, so the tonality can be matched to you clean tone or used to fatten the Mids.
One of our customers (a vintage plexi owner) commented that "the G2D Classic is as near to the real thing as you can get". This pedal sounds exactly as it looks.
As with most boutique pedal manufacturers, each pedal is hand-built and individually tested to ensure that each pedal preserves the guitars natural tone.
