The Boss Blues Driver is one of Boss's most popular pedals, and is also very popular with the pedal modding community. While some pedal makers (like Keeley and Analogman) make excellent modified versions of this pedal, some guys just like to do things themselves. So, if you're looking for a DIY Pedal Mod, there's only one place to look for the best kits - eBay! You can find some kits there at very fair prices. Just remember to be careful when you modify your pedal, but enjoy the fruits of your labor!
