I chose from the available ones in the factory 'shop'
Having had the tour, JB just let me to try them all out so I picked up the first one and thought wow, tried the 2nd and thought the same, and buy the 5th one I was beginning to think I wouldn't be able to choose!!
I prefer cutaways (though I'm no lead guitarist) but was open minded about a full body so tried everything. Fortunately I got to the L330C and was pretty convinced straight away.
It's sitka spruce top and walnut back and side I think. Suits me perfectly sound wise as it has a big sound when you strum but backs off nicely when you lighten the strumming. As a worship leader in church this is a perfect set up. I can't wait for it to settle in......
