I recently got a Music Man Passive USA sub and it sounds really nice, however one of the knobs was not affecting the tone. I opened the cavity and saw one of the pots was not wired into the circuit at all, just had a capacitor on it. I just wanted to clarify, is that is what its supposed to be like? or if it was a modification or factory mistake? I was under the impression this passive version had a volume, bass cut, treb cut. I already message their customer support but im hoping i might get some quicker responses here. Anybody with an unmodified passive setup want to send a picture? Or just anybody with any information really... haha thanks in advance.
Sounds like somebody rewired it, taking one of the pots (I assume the bass cut) out of the equation. I have a US SUB Sterling, but they're all active, so I can't help you with the control wiring photo situation.
Ya I figured as much. And it’s actually the treb cut that’s not there. (But I won’t tell They seller tried to tell me this passive model kept the same knobs and pick guard but they just skip wiring one of the knobs so it’s just a volume and a tone and then a pointless knob.... I was like I’m not expert but considering it’s not even a stock pickguard, I’m almost certain that’s incorrect. Who sells a bass with a nonsense knob? But ya thank you for reassuring me. Hopefully somebody will send a pic so I can get it wired back up.
Pickguard? Didn't they only make SUB Stingrays and Sterlings? The only MM basses I can think of with controls mounted on a pickguard are Stingray 5s and Big Als. I've never personally seen a passive SUB Stingray, I may very well be wrong and the seller may very well be telling the truth.
Idk what your asking but ya this bass has a pickguard. The USA subs had that metal looking pickguard. Look like a sheet of industrial aluminum or somthin. Think they came in black too. But this one has a pearloid. And the controls aren’t on the pickguard. But the pickguard was changed, I was inquiring to see if the knobs were as well.
Technically, there were no SUB Stingrays, there just the SUB and SUB 5. There was, however, a SUB Sterling. The passive has bass and treble passive roll off. They are good sounding basses.
This is what I’m talking about so there’s no confusion. It’s not a sterling. But it is a sub. And made in USA. And it’s passive, so I’m on the hunt for a picture of a passive setup or wiring diagram.
I could find out how to post a thread.... I’m embarrassed... I signed up but couldn’t figure it out so I came here. I Found a few threads talking about same thing but never found the diagram. I emailed customer support though so hopefully they will be able to help. I’ll go fiddle with the ebmm forums against tho.
hang on, i will go get mine and take a pic in a couple of hours. edit: EBMM SUB passive {} View attachment 3800401
not a PHOTO but a diagram. Mine had a bad middle pot so I redid the whole thing. For grins I used PIO caps. It sounds awesome. One of them is large. So, if you don't buy into that voodoo you're probably doing yourself a favor.
You need to go to the SUB Club,and you can get the right information. The SUB you have is made in US,and assembled here in US,on same place as the Stingray's. Were manufactured 2003-2006.
You’re too kind - quite literally, I’m afraid. Electronics are a closed book to me. However, Musicman customer service will know, and they’re usually helpful enough to provide a wiring diagram as well.
MusicMan helped me a lot when I fried the pre-amp in my Sub Sterling about 5 years ago. I installed the 9 volt backwards. You can do that in the battery boxes on the US SUB basses beware! They sold me a new Pre-amp board for $75. I installed it myself. It works great.
