I wouldn’t bother with any personally. I don’t know how the SSS bypass is but the SBM non TB is fine. Initially I TB’d my SBM’s but then I compared it to my latest SBM with stock bypass, they sounded Identical, this got me wondering so I traced the stock bypass and discovered unlike regular non TB like on vintage EHX BM’s that the SBM’s ground the circuit while in bypass mode, hence, creating a clearer non TB and zero leakage. So I re wired all my SBM’s back to stock bypass, so the LED’s would work again.

Other than the bypass, which I imagine could oscillate on the SSS if its bypass is like the EHX vintage SS’s I wouldnt mod it at all. If it doesn’t oscillate it probably has the same non TB set up as the SBM’s.

I like SS’s stock, they sound great IMO.

BUT,if you do want to mod it I know where you can get some Soviet military push button switches made in the same style as the big silver switch but much much smaller and with a reddy/maroon colored button that would fit the theme of the SSS and look really nice, better than a mini toggle. They are cool switches and I was gonna buy a heap of them but I really have no use for them TBH.

IMO the SS makes a very poor vibrato so I wouldnt make any permanent changes if trying this mod.

Basically, the only pedals I mod is fuzz and distortion, I have always liked my modulation stock so dont know of any interesting mods for such pedals.

Nah, all I meant drilling enclosures for switches before testing the mods out etc.LOL
