Replacing tact switches....$280 versus $10 fix

I hear that. I've seen your spare parts auctions over the past couple of years too!

Have you ever used the OMRON tact switches on any of your gear? I may be ordering a batch from a distributor in Toronto.

About the tact switches, I've only ever used those I find on non-working "S" series samplers, so I unfortunately have no clue about the brand you're talking about. However, I'm quite sure there are a few threads here about them.
Sorry I can't be of more help about that.
