Mr Rob R. wrote back... to tell me that the 'mystery guitar' I knew he could name might have been made at the Teisco factory (could be labeled anything from Teisco Del Rey, Conrad, Silvertone... and a few others). Audition was one of their brands (he says)... but all made by the same folks. Not a bad recording guitar according to Rob... twangy, surf-tones, and generally the neck plays poorly (he used a better word)... unless you have a real whiz set them up.
Rob wants a Fender Jag with buckers and fixed/ addressed bridge... and pickups that split to single coil (just like MY Sadowsky Strat!).... sounds great Rob...! Here's a 'Jazz' photo for you....
