From the vendor
The Mod Electronics Tone Splendor MK2S is a PCB build with board-mounted potentiometers based on the Sola Sound Tonebender Mk2. The original Tonebender Mk2 circuit is similar to the classic Fuzz Face (and Tonebender Mk1.5) circuits, with an additional gain stage at the input for a more intense fuzz sound. It was a positive ground circuit, which can cause problems when using a non-isolated power supply. The Tone Splendor MK2S is a negative ground circuit, so it can be powered and daisy-chained with any common 9V pedal supply. Like the original, it has a very low current draw for a long battery life (battery optional).
