555 Variants

Will an LM555 work in a Crash Sync. It's the only CMOS timer I can obtain without going online.

Which timer is the best choice?

I haven't built it myself, but looking at the schematic, any 555 at all should work.
Incidentally, the LM555 is not cmos.

Ah well that could be it then. Thanks.

Also wrong datasheets. I am using a TLC555 which is CMOS but aparantly has a higher impedence than the NE555.

Im still trying to figure out exactly how this pedal works so I may be way off here but could the higher impedence mean that the guitar signal is not enough to reset the osscillator?
