I found in a local guitar shop what looks to be a mahogany or brownish stained ash Fender Telecaster Thinline (with the f-hole) in perfect shape for $500 OBO. It plays totally clean. One issue is that I can not find a serial number anywhere that is visible. Should I do some investigating on it or just stay away. Having never owned a Telecaster, I thought this would be a great deal to screw around with one. Need some advice on this.....
