Having problems with an Old Duncan Invader

Re: Having problems with an Old Duncan Invader

Sorry for a dumb question but why isn't he wiring the Invader straight to a volume pot? Also not not sure why he would be wiring the Duncan black to Ibanez white etc. If he is using the stock Ibanez pickup in the neck that would be wired separately to another volume pot no? Why is he wanting to connect 2 pickups together?

My "shorthand". What I mean is - Duncan black to the place on the diagram where the Ibby white was connected. Etc.

Re: Having problems with an Old Duncan Invader

I think he said about ten posts back that he didn't even solder the pickup down, that it's just being held on by old solder? That's a 'cold' solder joint isn't it? I'd think ACTUALLY WIRING the guitar would make it sound a lot better.

Re: Having problems with an Old Duncan Invader

With a cold or cracked solder joint, you would get a lot of crackling but he hasn't mentioned that.

Fernas, if you are getting sound out of it and both coils sound the same when you tap the poles and you're not getting any crackling, then the pickup is perfectly fine...so the problem boils down to three possibilities:

1) It is a neck invader in spite of what the sticker on the base plate says about "B M".

2) It is wired wrong somehow.

3) You may have the pickup backed too far below the strings.

Get a multimeter and check that pickup's resistance -- once again, 7.2k for neck, 16.8k for bridge. If you happen to get a reading of about 8.4k, then that means one coil isn't working, which doesn't automatically mean the coil is broken. More likely that would mean it's wired up in such a way that only one coil is in the circuit.

If you're still having trouble with it a week from now, send it to me and I'll figure out what's wrong with it and send it back to you for free.

I know you're in Argentina. The postage still won't be too bad.

Re: Having problems with an Old Duncan Invader

i've got the metter .... and some weird news .... when i try to see the resistance from my neck pickup it works fine ... but when i switch to the invader ... the metter stays in 0 :S .... but if i plug the guitar.... it sounds ... so i think theres something wrong with the wiring ... i don't know what you think ...

Re: Having problems with an Old Duncan Invader

....and it has a sticker that says "B M" .......

Invader or Fullshred Bridge model, wound by "M"... since you have invasdder poles, it´s probably an Invader iand not a Fullshred

Re: Having problems with an Old Duncan Invader

ok ... this draw shows ALL THE WIRES .... is this ok?

 

[Fernas]

Re: Having problems with an Old Duncan Invader

the pickup works (bad..but sonds) but the mettes stays in zero .... even putting the res metter wire to the black inv wire ... and the black metter wires to the green inv cable ... :S ... weird

Re: Having problems with an Old Duncan Invader

I don't know what to say now. It must just be wired wrong or maybe you have the meter set on voltage instead of resistance or something.

If at all possible, please get us a picture of the wiring in the control cavity.

Re: Having problems with an Old Duncan Invader

i donta have a cam ... that why i made that weird drawing :S

anyway ... y setted the metter to X1K .... y putted it on my old ibanez inf pickup and the meter says "14k" or something around trhere.. ...

i putted it to the invader black and green cables and it stays in 0 .... really weird .....

Re: Having problems with an Old Duncan Invader

Do it a different way -- as I said before, plug a cord into the guitar and select the Invader pickup. Put the meter probes on the other end of the cord -- one probe on the tip and one on the sleeve. See what measurement you get there.

If you still get zero, then the green+shield and the black wire are somehow directly connected -- both may be grounded instead of just the green+shield. Or both may be wired hot.

Re: Having problems with an Old Duncan Invader

yes ... i still get zero .... :S ..... this is starting to scare me ....

im really mad ... and sad .... i've been saving a lot of time for this thing .... i've been waiting for having this .... about 2 years ... and now i bought it ... and doesnt work fine ='( ...

any way ... i think im going to give this thing to someone that build pickups to see ir he can rewound the coils or i don't know ... something

Re: Having problems with an Old Duncan Invader

I'm about 95% certain the pickup is fine but it's just wired wrong somehow. Take it to a guitar tech if you can.

Re: Having problems with an Old Duncan Invader

ok im taking it to a guitar tech ... i give up

thanks a lot anyway!

Re: Having problems with an Old Duncan Invader

btw .. if anyone else has any minimal idea about what is happening with my pickup... just mail me please ... ferna182.at.gmail.com

thank you all

Re: Having problems with an Old Duncan Invader

Ok Good news! ... the pickup was repaired ... the problem was that the coils were bad ... BOTH of them ... a guy named Carlos Ardizzi fully rewounded both coils and now the pickup sounds just like HELL! ... sounds REALLY EXACTLY as a new duncan invader .... the metter gives me 16.78, 16.79 ... almost the original 16.80 .... and was really cheap .... $50 .. wich is about U$S17 really cheap for such a really hard work ... he did a great job ...

anyway ... i just want to thank everyone who tried to help me out here (special thanks to Zhalgligun) you guys are amazing!

c ya!
