Back in the days before you could just price-check online, I found my Strat Plus in a pawn shop in Ilderton, Ontario for about 400 bucks: probably the best steal I ever had. The Sperzel locking tuners are stock, and suggest it was made in late 1987 or early 88. They're a touch rarer than the Schaller tuners that followed and I'm a big fan of them. The Wilkinson roller nut is a giveaway too: it's a bit of a pain, and really limits my string gauges to lighter strings.
I have the American Standard trem bridge, but someone blocked the tremolo entirely on mine, and glued the stock bridge down. I play it as a hardtail and it's got a beautiful tone that's got the usual Strat quack but is far more rounded and balanced.
In many, many ways, the guitar resembles the Eric Clapton signature Strats from the late 1980s, from the brief period when they had gold Lace Sensor pickups instead of the later Noiseless ones. This guitar has the Laces and they sound brilliant and very clean, lending to a terrific blank canvas for building your guitar tone. One of the only things missing from the (much more expensive) Clapton signature guitar was the TBX tone pot in the back position, which I later added myself. Other than custom knobs and a shiny pickguard for cosmetic effect, these are the only mods I've made to it. All that's missing is the Clapton-profile neck based on Blackie; as far as I can tell, my neck is the standard, rounder curve of the 80s Strats.
