Boss DS-1 ''Synth Drive'' - Mod

Boss DS-1, everyone's first guitar distortion (or behringer, if you were a broke kid). Until this day the DS-1 is one of my favourite distortion pedals, when they are modded. Myself I own a Keeley modded, but a friend of mine, Can Ur, wanted a solid distortion with some settings where you can get some unfriendly sound out of it.
So we went with the JHS Synth Drive DS-1 mod. First, the DS-1 will sound much better, less shrill and tighter; second, you can get strange noises with the toggle switches under the footswitch.
switch 1: it sounds like a dying battery fuzz
switch 2: oscillation
switch 3: switch 3 is kinda hard to explain, the best way I can explain it ''fuzz octave up tremolo synthy'' sound
All these sounds are obtained from circuit bending
