Frank, thanks for responding. I'm guessing the folks around here have seen my question (excluding the cedar factor) too many times, and are silently screaming, "Use the search function!", and/or "Why isn't your wife here asking?". Both are fair comments.
Perhaps the responses would've been better if I was asking about a high dollar 12s used for food-and-shelter gigs.
The S12 is straight acoustic. Before we pursue purchasing a system, we're going to see if the older Bill Lawrence soundhole PUP that's currently in the Ibanez AW25 12s still works. IIRC it's a passive PUP with no controls. If it works and sounds good in the Ibanez, it'll wind up in the S12.
A local independent store that does service, and would gladly sell us a system
and charge to install it
, actually suggested trying the above first.
