Would that drain the battery all the time or just when active?

That particular design was meant to replace the individual saddles of a Strat-type bridge. There are other styles, including 'thinline' types which install under the one-piece saddle of an acoustic bridge. Fishman makes very good ones.

The original guitar jack is replaced with one that has a built-in switch. The preamp is only drawing power when a cord is plugged into the jack.
