The first steel string guitar I build was this orchestra model sitka spruce ovangkol with cutaway.
It's got a L.R.Baggs Anthem SL pickup system.
I also made an OM version with Nylon strings and classical neck dimensions (broader, flat fingerboard).
Both guitars got a back with x-bracing:
While the steel string's top has got traditional x-bracing, the nylon model has a modified version.
The bridge is a pin bridge:
The top wood is torrified Sitka spruce. Body wood is Bubinga.
