I would recommend the Blues Driver for sure!
Don't let that Boss logo scare you! definitely the best pedal they've ever made!
If you're looking for a boost for your cleans, like Dave's EMG pickups or a really fat overdrive, you should definitely buy this one!
PS. I've posted some soundclips on my page where you can check out the BD. Listen to Fat Old Sun
