got a vintage bassballs enclosure. what should i build in it?

[ode2no1]

i want to try to build something fun into this enclosure....if possible without drilling any holes into it. so that leaves me in need of a circuit that requires only 1 knob and 1 switch. what should i do? i've never been fond of the rangemaster so i want to steer clear of that.

Orange Squeezer?  Phase 90?  Built them both and love them.

Why not build a bassballs into it?

[ode2no1]

i was actually thinking about doing a phase 90 but i just bought a couple of the bad stone pcb's and already have a small stone on my board. orange squeezer though....that's one to consider. as far as building a bassballs....it just isn't something that i'd use. it's getting difficult to think of things to build that i'll actually use at this point in general though haha.
