Hello everyone. I should have introduced myself sooner, but I went straight to asking questions. Now I'm trying to play by the rules.

I've been a casual, non-pro Fender Strat (1959 with a '61 neck) lead player in various types of bands all over the world for about 25 years (I'm 42 now and I do not make money as a guitarist). Nonetheless, I know very little about the working "details" of electric guitars beyond what the pickup switch does. In fact, I went for about a 5 or more year stretch without playing electric guitar at all. In the last three years, I've been playing more than I ever did before.
A life-long friend who I have started recording with again in a state-of-the-art studio he built in the last year, collects guitars and bought me this one for a very early Christmas present about three months ago. He says it is a "custom shop" S-500 USA model and I have seen from this site that it is either a "see through" honey or orange finish. Also from info gleaned here along with a response to my registration from Craig, the guitar is probably a 1995 production with the three-bolt neck.
The scale of the fretboard is considerably larger (longer) than my strat and it has jumbo frets which are also new to me along with a solid Maple rather than my other guitar's Rosewood (slap) fretboard. Now that I've been playing it daily and have broken myself from the previous guitar's differences, all I want to do is play the G&L and learn about the unique features available to me with the S-500.
So please bear with my questions, many of which most of you have probably heard before several times, and try to help me understand this new phenomenal musical instrument. Just from the point of view of natural sustain, I am amazed.
