The CMAC Silhouette Specials that EBMM produced 6 or 7 years ago were limited to a run of 33 instruments with a beautiful cream finish and custom neck plate stencil, each personally signed and numbered by BP (and 1/33 was signed by Wayne Gretzky as well ?!?). I've watched them for years, and they don't pull any noticable premium over the typical Silhouette... The last one I played in person was for sale for $900, but I took a pass on it... Every once in a while someone will throw one of these CMAC guitars up on the 'bay as "rare" or "collectable" with an outrageous BIN or reserve, but they never move... The only EBMM guitars I've noticed getting "collectable" prices are EVHs and Mr. Horsepower (of course), and recently Luke I's, which seem to be going up slowly and steadily in value... Some one offs probably fit the bill as well, especially some of the CLB Foundation auction pieces or celebrity owned pieces like an AL actually owned and autographed by Albert, but they're an exception to the rule...
