[sdiy] Ice Box questions

[Gavin]

Don't know this pedal in particular but I have repaired literally hundreds
of pedals and more then 9 times out of ten the problems are caused by  cold
solder joints on the PC mount pots.  A nice reflow frequently clears up
these type of intermittents.  Hope that helps... good luck!
