I've been to Rockin' Robin before. They are good but I've also found WB music shop quite great. https://plus.google.com/102642981778688407461
Best Musical Instrument/Equipment Store Houston 2013 - Rockin' Robin Guitars
When Billy Gibbons's pre-ZZ Top garage band the Moving Sidewalks reunited earlier this year, guess where they came to get their gear? Every city has a music store staffed by musicians who can teach you not only how to play an instrument but how to fix it, too, and luckily Houston has been blessed with Rockin' Robin for more than 40 years now. It's been in its spot near Shepherd Plaza since 1980, featuring a fantastic mural of another of Rockin' Robin's best customers...the late Stevie Ray Vaughan. If you can make music on it — all manner of guitars, basses, mandolins, ukuleles, drums — they've got it, plus a wide array of amps and pedals that will make that instrument sound just right. Because it's just that righteous, Rockin' Robin even sells surfboards.
