2. Boss DS-1
It's the original distortion pedal, it's been around for decades, and it takes its rightful place towards the top of this list. From pure historical value, the DS-1 came along and changed the way guitarists thought about distortion.
Guitarists could get high-gain levels at much lower volumes, and original 1970s models of the DS-1 now sell for ridiculous amounts of money in guitar stores and on eBay.
We recently did a bitesize review of the DS-1, as part of a series of Boss reviews, which you can watch here.
But if the Boss DS-1 came in at second place, then which pedal took the crown?
