There are obvious parallels between car and guitar maintenance, and a guitar owner’s relationship with the luthier can often follow a similar dynamic to that of the car owner and their mechanic. For example, if you’ve ever owned an old Alfa Romeo, you may be aware of something called the ‘Italian tune-up’. The scenario goes something like this: the owner takes great care of his car, never driving too fast, always accelerating gently and keeping the revs well below the red line. But every few months, the car begins to feel sluggish and unresponsive, so the owner decides it needs a tune-up and takes it to the garage.
The mechanic pretends to listen carefully as the owner details all the symptoms, waits until he’s out of sight, then takes the car for a long spin so he can rev the crap out of the engine – literally. Having burned and blown away the carbon deposits that have formed because the engine isn’t being used as intended, the mechanic returns with a big grin and writes an invoice. The owner is delighted the ‘tune up’ has got the car running as it’s supposed to again, and the mechanic is delighted because he knows he’ll soon be doing it all again
