go with a Boss OS-2 Overdrive/distortion pedal. without a doubt the most usefull piece of gear i have ever purchased. it allows you to blend overdrive and distortion, so you truly can get a really phenomenal range with it. it depends on what genres you play tho, its not too good for modern, high-gain metal and such. its ideal for hard rock and 70's and 80's rock and metal. also nice blues tones
