Ibanez Artcore problem??

[calibre2001]

Hi all,

Just had a Seth neck installed on my AS73 (335 copy) to replace the stock neck bucker. Its brilliant. I've also readjusted the stock bridge's height to match the neck's output.

Both neck and bridge switch positions are plenty loud. However, when I go in between, which I believe is the neck and bridge in parallel, there's a noticeable volume drop .

Its not necessarily a bad thing for that jangly , twangy stuff but I'm wondering whether this is normal.

To my knowledge, the wiring is stock. Thanks

BTW I am new here and like what I read so far!

Well, how twangy is it compared to before? Could the pickups be wired
out of phase?

I had a Seth in the neck of an AS-100 and can concur that its a great
match to that kind of guitar.

It's more of a volume issue rather than twang. To answer your question, it's a more solid, non-Tele twang than stock pups together.

In the in between position, the neck pup has greater authority here. It's not independent of the pup volumes like the 50s Gibson wiring though- the middle position.

I left all knobs on the Artcore wide open to confirm the volume drop.

Wiring is stock. What is out of phase anyway?

Does it get louder if you turn down one of the pickups a bit?

No, it gets louder. By turn down, you mean volume?

Could be due to the bridge pup? It seems underpowered compared to the Seth neck-er.

Your pickups are out of phase with each other. You need to swap the leads on your bridge pickup.

That, or get a bridge Seth.

If I do change the bridge pup , would I still need to reverse the lead wires?

Curious, how is this phenomena possible- out of phase?

Think of your string vibrating, up/down, making one of those
waveform thingies. Your pickup sits under the string making
and electronic analog of that, the string goes away, the positive
voltage increases from the pickup, the string comes back, and
a negative voltage appears.

Your two pickups, if wired properly, will both produce positive
voltage as the string goes away and negative voltage as the string
comes back. The voltages are mixed together and provide a different
tone than either pickup alone (but don't really gain volume).

If one pickup is wired backwards (out of phase) then it produces
positive voltage when the other pickup is producing the negative
voltage. The voltages cancel out and you DO lose volume.

However, the string vibration is much more complex than that. There
are some "harmonics" in the string vibration where the string is moving
in opposite directions over each of the pickups. These frequencies
are higher, and so out-of-phase gives a more nasal, twangier, tone
than if the pickups were in phase.
