Hi, and thank you for your kind words. I really appreciate that! Well, my experience is sort of similar. The MPX-1 has a vibe of its own and I feel that it works better alone than in conjunction with the other FX in my rack. Not to say that it don't work with others, or to take away any credit of its cool sounds, but for this application I just find other FX more pleasing. The Marshall on top of the OD100s is an original all stock '71 big box 50w bass spec and the other one, on top of the Fenders, is a kit build of sorts of a plexi small box 50w bass spec. There was a big thread on it over at HRI and the thread will be added to the HRI Archives in the near future. But, on top of my head there is.. let's see.. an original Marshall 1987x headbox, Ceriatone chassis and faceplates, Classictone PT, Mercury Magnetics Choke, Merren Audio OT, NOS Mustards.. hmm.. there's also some NOS Allen Bradley's just for kicks and a couple of NOS Mullard tubes in there. We went all in on that build for sure. It's sounding better every day and it's really close to my original '71. I used the kit amp (nicknamed Mikey) for the solo on this tune together with the Tubedriver. The Fenders are a '67 Pro Reverb and a '67 Twin Reverb, both stock. Thanks! //M.
