This is a home made pickup unwinder made by Bill Crozier, after he was unsatisfied with the sound of his Tex Mex pickup. He designed a pickup unwinder to unwind the pickup wire onto a reel, and then used the same setup to scatter rewind the pickup. He mounted the pickup on a rotating Lazy Susan, and the wire take-up spool on a record player.

This easy to follow PDF guide shows you how to make your own electric cigar box guitar. Its author Ed Vogel says

This pdf file from Make magazine shows you how to make a three string cigar box guitar and matching amplifier. At an estimated cost of $15 to $30 this project uses no standard guitar parts: for example the machine heads are eye bolts and the frets are filed down nails held on with rubber bands. You could substitute some of the parts for real guitar components if you want to make a luxury version.

These are two examples of pickup winders made out of LEGO. They use the motorised Mindstorms , NXT type components to spin the pickup bobbin. I haven't seen any LEGO winders with an automatic travese mechanism yet, but it won't be long before someone builds one.

The first is a pickup unwinder, for despooling a broken pickup, by Scorpion097 .

Rish developed the lego pickup winder further, making a more conventional design with LEGO NXT components for winding pickups.

GeoMag is a magnetic toy construction system. It connects together using short magnetic rods and little steel balls. Niels Kaagaard noticed the resemblance of the GeoMag rods to the pole pieces in a single coil pickup and proceeded to make a pickup out of them.  When you remove the plastic coating from the GeoMag rod you can see it is a steel bar with neodymium magnets at either end. To work as a pickup pole you need to remove one of these magnets. Niels then made some bobbins from fibreboard and wound the pickup coil around the GeoMag rods using his own hand winder.

Every guitarist has a wish list of dream guitars they are never going to own. Some guitars are just too expensive, like the Gretsch White Falcon. Some are just not for sale, like Jimi Hendrix's psychedlic Flying V.

Now you can have that guitar you have always wanted, at least a minaiture paper version of it. Paperguitars.com has loads of free cut-out papercraft guitar models. You cut out all the pieces and glue them together to get the guitar of your dreams

Traditional guitar pickups used alnico magnets or ceramic magnets. Neodymium magnets, a form of rare-earth magnet, have not often been used in guitar pickups. These extra strong magnets are becoming more and more available, and this instructable shows how to use them in a single coil pickup. The design uses screws as pole-pieces with small circular neodymium magnets underneath the pickups. Also contains a bit on how to pot the pickup in wax.

Slapping is a bass technique where you hitting the string with your thumb near the start of the neck, often pulling or snapping the higher strings with your index and middle finger (popping). This technique first appeared in the 1970s and was synonymous with the funk music of that period. Larry Graham, bassist with Sly and the Family Stone, was one of the bass slapping pioneers. The eighties saw a new generation of slappers, like Mark King of Level 42.
