Volume Knob on MD 6

[donf]

On my Mod 6, if my volume knob is all the way up (loudest), I start to rotate it so the volume lessens. When it gets down to about, say, 2, the volume is almost gone, but if I continue down , 1, then all the way off, the volume becomes loud again. Any fix for this or do I need to replace the volume knob.

I think that's more Pot and electronics related than the knob itself. Unless there's a faulty analog connection.

you could spray contact cleaner in the pot and rotate it a few times to see if it helps, or just spend a few bucks to replace it altogether.

Yea, it's not the physical knob itself, that works fine, it's the electronics. I was wondering if it's an easy fix, or to just replace it.

Replacing it might be the easiest thing. Any where I can get one, for the Mod 6 or is it just a general part order.

It's not that simple--the volume pot on a Mod6 is physically attached to the JE-1200 electronics board. You'd basically have to ditch the active electronics to replace the volume pot--I don't know why Jackson made it that way.

Re: Volume Knob on MD 6

you should be able to detach the pot from the board, and use jumper wires to connect it to the new pot, just make sure it is the same value pot-I believe they are 50K (not 500K) or maybe 100K.

You CAN take pots apart, but gertting them back together and not breaking off the little metal tabs is the tricky part. Besides, even if you did take it apart, you would find that the contacts are most likely totally crudded up and worn out, so what would be the point?

How is the pot physically attached to the JE-1200. Is it by wires that can be unsoldered and resoldered to the new pot? I don't have the guitar here with me right now, so I'm just throwing this question out.

I'm at work and can't look at the couple of spare ones I have sitting around--it's pretty solidly attached, I know that. Not just soldered or held by a couple of screws. I think that the JE-1200 circuit board might actually extend 'into' the volume pot, if I recall correctly.

One alternative is getting another JE-1200 w/function volume control. My spare JE-1200s are ok, but I think I may have cannibalized some of the wiring off of them when I was in a hurry... [img]/images/graemlins/crazy.gif[/img]

<font color="aqua">Actually, the tabs on the pot are "cut" down to a thinner size (I'm sure they were manufactured that way) and those are inserted into the circuit board and soldered. That is the only way they are held on. I have never seen them screwed or mounted to the board any other way but anything's possible! I have a few different boards here, all Jackson Electronics, and they are all just soldered on. I guess they figured the boards are so light, there really was no need to mount it any other way. Hope that helps. </font>

I'm gonna take a look at mine tonight. Maybe I can improvise. [img]/images/graemlins/scratchhead.gif[/img]

Is this a common occurance, cause it seems like the pot is working correctly when you turn it. It goes up and down depending on which way you turn it. It seems like when you turn it all the way off, it bypasses the actual off position and turns the volume up to max (when it's suppose to be off). There doesn't seem to be any looseness on the dial, it feels normal when being turned.

Re: Volume Knob on MD 6

I'd just replace the pot. You can adapt the circuit to any standard mini-pot. I think those were 250K ?? (don't remember)
Anyhoo, the pots are only about 3 bucks and it's an easy swap if you have experience with soldering. If not, take it to a tech and I'm sure he won't charge you much..

Re: Volume Knob on MD 6

that pot seems to be blown
you need to swap it
