just tried it on breadboard...perfectly fine..
no need for seperate grounds etc...using ts555cn .no ticking at all........
with my gain and volume full on my mixer....

btw i have an in jack and out jack permanently fixed to my breadboard
all grounds connected on same rail......if the guitar jack in/outs are not plugged in it wont work.....
edit: i see what you mean about it not starting after removing power after a while...i connected pins 4 and 5 with a jumper on the ts555cn and it sorted that out ok...
seems the ts555 behaves slightly differently to the standard cmos555...this can behave differently according to leds used also.....i'm using 5mm high bright for ldr/led..
and 3mm yellow for rate...
ok heres what it has to be when using the ts555cn ok...notice the pin4-5 connection. if this is not connected it will take about 20 seconds to flash...
here ya go.

heres the vero for the ts555cn version ok.

i have updated my gallery to include this and deleted all other versions ok........done!.
