Not to be a killjoy about the visit or to state the obvious but the while you wait part of the equation is going to be determined by what you mean by a general overall. It's one thing to replace a tailpiece, bridge, or faulty PU quite another to add front LEDS, replace the electronics, add controls, etc.
There is no question, however that a visit is well worth the time and cost even if it just results in your dropping off your Further and the folks at Alembic shipping it back to you at a later date.
