well if you want an original idea try this.

1. lay a naked and willing lady/tart/bird/crumpet etc on the bed.

2. draw 6 (7 if you are into korn/bizket) lines representing strings from her neck down to her interesting bit. Draw machine heads on her face. Wammy bar on her hip. Pick-ups on her belly. And vol/tone knobs on her, well you decide.

3. plug in your lead and play away. (you can put a CD on if you need insperation,LOL)
