Food for thought for anyone wishing to recreate Joe's base sound (DSL 100 and 808) Unless you are able to run the DSL flat out like Joe, The best interpretation I can find, and I have been searching for a long time si running my DSL 100 on the clean channel without the crunch switch in (same as Joe) and having the gain set to full (Supper crisp clean with a hint of break up) and the volume at around 11 o'Clock then I run a Rothwell hellbender straight in the front. My 808/TS9 just doesn't have enough dirt at this volume.
The Hellbender is roughly the same price as the 808/TS9 but is so much more versatile. Having multiple gain stages, it can clean up to virtually no gain on single coils and a little dirt even when the gain is set to full (Full plexi crank) and even when you run it flat out on the guitar, it is the only OD pedal that I have found (I have tried virtually all of them in my time) that will clean up by just strumming/picking lighter, the response is just amazing. That's what you get for buying hand wired pedal from an audio engineer!
