Would these circuits work much differently on a dual rail supply? +/-15v

You may try J201, or 2SK30.
I mean for the clipping transistor. Those things were expensive now I have a pile of them to use up.

Re: Bsiab Transistors

If you know how to etch your own PCBs its possible to make smd to to92 adapter boards, its what I do for my pedals. You can buy them premade but the ones I've seen are way too expensive to be worth it.
