I once had a previous employer tell me "all you know how to do is change tubes." I wasn't bothered so much by the fact that he was wrong (my lasagna making skills are unstoppable.) It was more that he somehow thought of the most common and requested bit of maintenance work as unworthy. It would be like telling the mechanic at Speedy Lube "all you know how to do is change oil" without realizing that there were multiple nation wide franchises doing millions of dollars in business all for providing a basic and much needed service. Anyway, all I did to this Fender Hotrod Deluxe was change its tubes.
