Yeah, there's a few builds that I'd love to play. I wonder if there's a way to do that, some kind of rotating test play thing.
In any event, I'm also looking forward to playing this. I haven't played a fretless in many years.
I've done this with contractor forums that I participate and/or moderate.. We've done some with hammers, drills, tile slicers etc... and send them to the next guy. It's actually fun as heck provided someone doesnt decide to ruin the fun. Shipping would be a bit costly for this but would be 100% worth it imho.
