is best known for his electric violins, but also does instrument repair in the Bay Area. Here are a few of his e-mandos: a 4-string beauty with a whammy bar, another 4-string made of cast glass that lights up when played (John is a glass artist as well as a luthier), and a pair of 5-strings. John writes: "I’m still mostly making electric violins, but am always open to other instrument commissions." Learn more at his Web site.
