without altering anything else at all.
I don't know any mod that would suit this condition, maybe Laurie would come up with a solution, he is the most knowledgeable here.
In order to not alter anything, I think the modification must happen near the circuit's output, maybe you could swap the level pot for one with a bigger resistance, something like 50KB, or to low R11 value...
I'm shooting in the dark here, better wait for Laurie.
As a plan B, if you want a super booster to put after the SD-1 (or any other drive pedal), I would recommend the Glass Blower, it is completely transparent, totally clean and
very powerful (27dB).
It is a DIY pedal, but it is very simple and easy to build.

Just the pcb:

And a complete kit to build it:

EDIT: The pcb in the kit is so small and your pedal is a SMD, with a lot of space inside the case, so you can put the GB inside the SD-1, connecting the GB in between the SD-1 output wires and the output jack. Same 9V connections and a trimpot as the gain pot in the GB, so you can regulate the amount of boost.
You know what, I will order a pcb and put a GB inside a DS-1 SMD, to use it as a strong booster, solving it's low output "problem"!
