Sounds great. Maybe put more variety into the giveaways though. Years worth of strings, 500 picks, Guitar Accessory package (winder, tuner, cleaner etc) CD packages, software. Maybe even get something going with a guitar magazine offering a free subscription or back issues. You might find that some companies would be willing to help out with giveaways just for the advertising exposure they'd get on GuitarTricks.
Bigger prizes like guitars or amps could be saved for special occasions like christmas.
