According to the [Boss official website](http://www.billyduffy.com/gear/boss-sd-1w-super-overdrive-pedal/), Billy uses the SD-1W. "Another pedal that Jamie passed onto me when he joined Death Cult (and swapped guitar for Bass) was his BOSS OD-1. I used that as Overdrive in the early years of the band and this ‘Waza Craft’ updated one 'does exactly what it says on the box,' i.e. it gives [the] option to add more bass bottom end tone and sustain without making the effect too boomy. That’s desirable in all overdrives, as the bane of using them was that the sound got thinner (more trebly) when you switched it on. That’s been resolved by the Waza version and allows Boss to offer ’boutique’ pedal finesse on a more readily available model.”more
Passionately designed by the master engineers at BOSS in Japan, the Waza Craft SD-1W Super Overdrive delivers a premium stomp experience that fans of customized pedal tone will love. Crafted with an ear for highly refined sound, the SD-1W hot rods the famous BOSS overdrive with all-discrete analog circuitry. Standard mode captures the classic SD-1 sound while Custom mode offers new tonal range and gain.
SD-1 is one of the most famous overdrive pedals out there, simply because it sounds good and it's a BOSS. But, for those who want a little more power and definition, there was always MODs available for the SD-1. I believe that Boss just saw the opportunity in there, so now they have this new version where you can choose between the original sound and, let's say, the "MOD" sound! I doubt you need anything else than the great SD-1W.
This is a great drive and includes both the traditional SD1 sound as well as a custom mode which is fuller and more modern sounding. I prefer the latter when used alone but former is good as a boost into another drive as it has more of a mid hump.
