A sizable percentage of Studio California's workload comprise straightforward refinishing projects, and also restorations to "as new" condition of Rickenbacker guitars and basses, such as this Jetglo 370/12. Though the guitar was essentially in "factory fresh" condition, this owner did opt to have the standard mother-of-pearl fret markers changed to crushed "sparkle" mother-of-pearl, normally seen on mid-to-late 1960s instruments. This simple and relatively inexpensive upgrade lends an unusual and subtle "vintage" look to what is otherwise a standard-issue late-model guitar.
