Mini version of SD-1

prlgmnr

I'm making a mini-board of mini-pedals to live in my mini-house with my mini-amp (Yamaha THR10)

Outside in my maxi-rig I like to stack a Spark Boost into an SD-1 into a Green Rhino.

My mini-rig so far (overdrive wise) is Tumnus* into TSmini, but I really want to add something with asymmetrical clipping in between those two, what are my options? I've seen a couple of DS-1 clones but that's a different nest of ferrets altogether. 

*Yes this is probably going to end up spending more time outside in the other rig.
