    I'll try and keep a long story short....

    The preamp on my Modulus Quantum 5 (EMG 2 band EQ) started to go on the fritz, so I decided since it needed replacing I'd overhaul all the electronics which are from 1993. I test drove a few and found one that I really loved.

    The shop owner had no idea what type of electronics were in any of the Quantums in his shop but I finally convinced him to look at the inventory sheets to see what they had in them. The one I like had M45C pickups with the NTMB preamp. So with this information I went off to the repair shop that was recommended by the dealer to get my bass hooked up.

    When I got there they tech told me that, according to the Bartolini technical manual, there is no way to do that preamp/pickup configuration without using a toggle switch. I told him that I had just played one 1/2 and hour ago. He said, "it must be something custom for Modulus."

    So, either the shop owner gave me the wrong info on what was in the bass in his shop, or the repair guy needs me to get him a wiring diagram for how to wire it up. Can anyone help me with a wiring diagram for this set-up? Does anyone know if there is anything custom or rare about it that I need to know so I can order the right parts? The set up I played had four knobs, and one was a stacked. Not sure if there was a push-pull involved.

    Maybe the repair shop just has an old or incomplete wiring book. Any information would be really great. I appreciate all your help.
    Thank you,
    Dugan

    Wow, thanks Mike. I think that's exactly what I will need. In Fact, I may even go with the one for three knob control(HR-3.4). Then, I don't need to add another hole in the cavity, and I prefer the separate volume controls! Heck, I think I can probably just do my self if I don't need to drill through the body.

    THANKS!
