Re: MXR Distortion + : tell me
Hmm, right... not sure about that one, I know he had those Marshall's cranked all the time through Altecs which may have helped give him that fuzzy grit. Maybe he ran 2, one as a sublte boost on all the time, and another for a little more sustain on top of that. I think he also used high output distortion pickups, not sure if they were Duncan's or Dimarzio's. I never saw him live so, not too sure, but his recorded tracks are obviously double tracked or more. I'm sure you can probably find more detailed info on his specific rig somewhere on the net.
Big old Marshall amps such as the NMV plexi's or JMP's can do some pretty magical stuff when theyre cranked, that's not a new thing by any means. But yeah if you look at all the high gain amps of today compared to the smallish amounts of overdrive those amps offer up, it's really hard to believe, but volume is the key with those things. I had a pretty lengthy discussion with George Lynch about those old Marshalls they used in the 80's and he pretty much told me that all those guys, before modding was super popular, was just finding an old plexi or pre 73 NMV that sounded decently good and wouldnt blow up when you cranked it so much. That's it... better tubes (which makes a huge difference) was also more available at the time such as Mullards.
