Where real pianos have strings that typically require the services of a professional piano tuner, the Wurlitzer electric piano can generally be tuned by end-users. Instead of a string being tuned to correct pitch, the Wurlitzer is tuned by raising or lowering the pitch of a vibrating reed. If the pitch of the reed is flat, it may be raised by removing a tiny amount of lead at the end of the reed. An X-acto knife (available in art supply stores) is generally the best way to do this. To lower the pitch, a tiny amount of lead may be added, usually by flowing a tiny amount of multicore solder onto the reed, then scraping off any excess. Fortunately, Wurlitzers are built ruggedly enough that tuning is only rarely required.
