I find it fun to mutate circuits on a given board into something else where most people would say "Just build it on vero" or "You can build it on perf".
For example, I've repurposed a GuitarPCB Red Special (modded ROG May Queen) into a Barbershop after noticing similarities between the two circuits — it came about when wanting to add a tilt-EQ to the Barbershop. While it's not a tilt-EQ on the Red Special, it was a fun twist (you May have to twist some transistor legs around ) to make a Barbershop with rudimentary EQ.
I've got the Chop Shop, but will build it straight up. Might have to order another one, as I've always wanted to build a Mini as well.
Adding a JFET boost onto the front of the Chop Shop may be easier than adding a BJT to the end of the Son of Ben.
