The shops situation in Miami is sad, to put it mildly.
Two Sam Ash's...One to the north of Hialeah, in Miami Lakes.And one to the southeast in Miami.
Both fairly short drives from you.....Good luck.
**GCs are farther to the north in Hollywood and one in south Miami.
*On a smaller scale: The Guitar Nook on Biscayne Blvd and a few custom shops.
