i bought an old mark iv short head the serial number is IV0045* on ebay about 5 months ago , it worked fine for a couple of days and then it took a ****, i took it apart to look at the circuitry and noticed there was writings on the side of the chassis along with the techs name, i didnt think too much of it but i thought it said randy or randall s. or something like that. I gave it to a repair tech the other day and when i was looking around mesa website i noticed randall smith is the founder of mesa/boogie. When I get the amp back and i found out it was worked on by randall smith with his signature would it increase its value at all?
