JHS 3 Series Overdrive
Based on the JHS 3 Series Distortion· 6 other boards clone it
From the post
Got some request for Overdrive and Distortion in the the new JHS 3 range. Was a bit hesistant at first since those are basically a Tubescreamer and a Rat with some simple mods....not "mostly own designed";-). First up a Tubescreamer....sorry JHS 3 Series Overdrive.
