From the post

Info about the original:

The Talons is an extremely versatile high gain overdrive that serves up the full range of gain from transparent boost to heavy saturation, and all points in between. Unlike all our other overdrives, the Talons was not designed to emulate any specific sound or era. The presence control gives you a wide range of top-end contour and the active 3 band EQ allows you to sculpt your tone to perfection. The Talons can be powered at the standard 9v for a warmer amp-like tone or at 18v for greater headroom, more volume and a brighter, stiffer grind.

  • 4K6 top left by Gain 1: printed clearly, unusual value
  • 3M2 left of the 100n near TL072: printed clearly, unusual value (could be meant as 3M3)
  • 100R in the lower middle: reads 100R at zoom, looks like 100K at full size
