I cannot be the only/first person to realize PRS provided me a free Wah pedal with my new semi-hollow CE24. I play probably most of the time unplugged since it's easy to grab and go. A couple weeks ago I was playing/strumming and I heard something that seemed unique - and I like it. Finally realized it was the effect of my arm passing (opening and closing) the f-hole. I've never had a semi-hollow before this, and acoustics have never sounded like this (assume because sound hole is more central). Anyway, fun little effect (non)pedal.
