I'm planning a build for s friend of mine that plays acoustic live. I play a bit of guitar, mostly electric, but I'm also and foremost a sound guy. The board I'm planning is a utility board for starts with an AB switch. After Line A there is a tuner, and then it goes to the stagebox. This channel can be used for his monitoring. He wants to hear himself while tuning. Line B got an volume pedal to compensate the gain difference between his chords playing and his picking. This line goes no the stagebox and will be used in the PA.

Aan a sound guy I often use a chorus and a reverb (room or plate) on acoustic guitars, but I'm wondering if there are any other effects you would put on an acoustic board.
