Sad Truth: Something you're selling is only worth what someone else is willing to pay you for it.

Small Justice: This rule also applies when you are the buyer.

IIRC, the axe you're looking at is a mid-80's special issue that had a rotary PU/phase selector, with the two remaining knobs doing Master Tone and Master Volume duties. The headstock face is the same colour as the body (usually metalic red), and the decal says "The Strat" instead of Stratocaster.

My personal opinion of EMG active pickups is that they suck out the soul of a guitar, and replace the sound with a generic EMG 'tone'. No worries - you easily can sell them off to someone who likes them, and buy something more to your taste. The original Lace Sensors were very thin-sounding, and they would have been much harder to get rid of.

I am a firm believer in trying a guitar before you buy it, although I have bought 4 guitars on eBay. You get the opportunity to check it out on Sunday. This is good.

If you like the guitar, you're back to the above rules: Sad Truth & Small Justice. Ideally, you will both be happy with what you find, and you can work out a mutually satisfying deal. A straight swap is probably a realistic outcome. If he's coming to your place, then he's already absorbing the shipping costs (and hassle). If you're going to his place, you're entitled to some compensation for dragging that cab around.

furthermore: Money was invented because an inherent problem with barter trading is working out differences in value. For instance, how do you 'make change' for a guy who wants to trade six chickens for your cow? The main thing to remember is that an ideal business transaction is one where all parties come away feeling that they are better off. If you're happier with a 'new' guitar in hand than you were with an extra speaker cab taking up space in your life, do the deal. Don't worry about whether you might have made an extra buck or two.
