What are Baritone models tuned to; what is the difference between them and regular guitars, and what are the string gauges?
ESP introduced baritones as a 6-string alternative to a 7-string. They feature a 27″ scale length as opposed to a 25.5″ scale (which is fairly standard for most guitars.) The increased scale length (distance measured from the bridge to the nut) allows the guitar to be tuned lower than standard, while still retaining proper string tension. ESP Baritone models come from the factory with .056/.046/.036/.026W/.017/.013 gauge strings and are tuned B/E/A/D/F#/B.
