I just picked up a Suhr Riot as part of a Craigslist deal... So far I'm pretty impressed. However, I just noticed what seems to be a short in the voice switch. I'm able to switch to the left and right positions just fine but the center seems problamatic. If I push it towards the left side a bit I can get a volume jump. Anybody come across this? Unfortunately, since I'm not the original owner I don't think the warranty applies to me.
