Dave Smith Instruments SYNTHESIZERS

Hey guys, after getting a board swap on my original evolver in 
exchange for a rev 1.2, I'm having problems with the start/stop 
button - it doesn't trigger reliably, often double triggering or not 
triggering at all when pressed. Dave suggested simply reseating the 
button cap, but that didn't seem to do any good. I don't really want 
to have the board replaced again or send it away (especially not for 
a minor - but bothersome - problem such as this), but I'm afraid if I 
replace the switch that would void my warranty, and besides, I'm 
without a decent soldering iron at the moment. What would you guys 
(and ladies...p.s., I'm single and so's my evolver ;)) suggest?
