GAS is a debilitating problem for those who spend too much time fingering the frets. If you're suffering from a near-terminal case of Guitar Acquisition Syndrome, Blue Note Music can help you deal with your cravings by simply allowing you the opportunity to fondle hundreds of their exquisite fretted instruments for hours at a time. "It's a shop like you'd find in the old days," said Bishop Sweet-Daddy Lovelace, a local gray-haired, dreadlocked guitar hero. "You can practice your licks, see your friends, and play guitars that make you want to keep on playin'." Whether you're in the market for archtops or mad, bad, bone-crunching electrics or an exquisite flat-top guitar, Blue Note's got 'em all. Current favorites include a 1948 Gibson L-5 ($12,000) and the equally rare, brand-new, handmade Michael Lewis Deluxe (a bargain at $6,000) or Ralph Novack's exotic fan-fret Stratocaster or the many Breedloves, Martins, Gibsons, and Taylors.
