thank you for the confirmation, ciaran. am looking forward to trying these as i have a little pile of 'maybe' chips from builds that never worked that may be fried or fine.
will try a few between 330r and 1k. i use 1k in my stomps for brightness.

btw have you seen anything that does the inverse? that goes in the socket in place of a chip but does the same sort of instant diagnostic thing?

eg, something 8 or 14 pin that you can plug it into an ic socket in a layout and the lights come on (or don't) if those pins are getting enough power and are properly grounded to run a chip.

i know i can take readings of voltages easily enough, but i was thinking that something like that would speed up debugging as you could just fiddle around with a troublesome circuit (jumpering here, grounding there, etc) and see immediately (no stopping to take readings) what was going on in the ic socket.

that would be interesting. maybe these above builds could be tweaked to run in reverse or something?
