Timberline® T20HGc All Solid Wood Tropical Mahogany 12-String Harp Guitar
The harp guitar has six Sub-Bass strings tuned E-G-A-B-C-D in addition to six normal tuned strings
I use .011 ‘s for the guitar strings gauge.
The guitar pickup is a K&K mini which is installed inside the guitar in the bridge.
I really like K&K because they sound great, and don’t use batteries.
I also keep two Oasis humidifiers in the case at all times.
