Not happy with Nazgul or Full Shred 7's...

What I'm saying is, have you run the guitar straight into the amp with no pedals, and nothing in the loop, to hear how it sounds? Make sure it's not some kind of impedance thing with a pedal or cable darkening your tone?

Ah! No not yet, but I'll try it and see if I get the same results or not.
 
The tone control was replaced with the volume pot because the previous owner replaced the volume pot with a Tesi LED killswitch... so I had to completely rewire the guitar for it to be fully functional again when I got it...

And I have a few extra Alnico V, Alnico VIII, and ceramic magnets that I could try swapping with, so that too has crossed my mind...
For 7-strings? I would think the magnets are different dimensions on those on 6-strings. I've never seen 7-string sized A8, personally.

I would try the Ceramic first, personally. That ought to be the brightest.

You could also try the short hex poles in the Nazgul. Based on DCR, I would be willing to bet the Nazgul with the same polepieces and magnet as the FS's coils would sound brighter.

Other than that, you're trapped in a dead end. If a 1 Meg pot doesn't solve the issue, then there's either something wrong somere else down the chain, or that's simply the way the guitar sounds. Is it like that acoustically as well?

That might work, but I'm limited as to what else I can put in the guitar itself... the previous owner bored the volume.pot hole for a Tesi Killswitch, so the tone pot was removed and that is now my volume pot. However: between the very responsive treble, bass, presence & resonance controls on the amp (a Peavey 6505MH...), & with running a Boss EQ-200 10-Band EQ in the effects loop (running both EQ channels back-to-back), I'm sure I can tweak something somewhere to get it dialed in better...

But I would have thought that between the Basswood body, bolt-on maple neck & maple fingerboard, it would be a fairly bright sounding piece on its own... and in the demos I've heard, the FS7 was a bit warmer than the Nazgul & I would have thought that the brighter Nazgul would have helped tame some of the low end better with the low A tuning, but somehow it's not...

All those tone controls are post distortion. Even without a pot, you can put in the right value resistor to act as a hi-pass. There’s one you can look up called the “demud mod.” It’s nothing more than a resistor across the wires.

I thought I saw on this forum here somewhere a while ago thay a 6-string magnet would work in a 7-string pickup, it would still be long enough to make contact with the polepieces on the low B and high E, so the swap has always been something I've been curious about...

I could try swapping the polepieces between the FS and Nazgul, but I'd only be able to swap one coil. The other coil on the Nazgul has normal slug polepieces... and between the two, the Nazgul is a good bit brighter than the FS in its own...

And the guitar doesn't seem to be like that acoustically from what I noticed... the only other guitar I have a similar issue with is my '99 UV777BK that oddly enough is tuned to A std as well... that one has a set of DiMarzio D-Activator 7's in it and I had to swap the volume pot on from a 500k to a 1 Meg, and it worked wonders to tame the woofy low end it had...

A 2.5" magnet will work. Not the greatest photo but you can see how it'll line up. I've used 2.5" ceramic magnets in 7 string pickups.

So I've tried it again with a few different cables going right to the input of the amp & thru my floorboard like normal, and I'm fi ding the same result: it's sounding like the tone control is rolled all the way down, and there's no tone pot in the guitar at all...

I've also tried my other A tuned guitar - my '99 Universe with a D-Activator 7 set, with a 1 Meg stacked volume pot - and while the tone is a bit clearer and nowhere near as muddy, it doesn't seem like it's as hot (output-wise) as it should be... (as a side note: I have another Ibanez RG7620 with DA7's in it tuned to std B w/ a normal 500k volume pot, and the tone is a bit brighter and more aggressive in comparison...). So I am starting to think it's gotta be something with the frequency difference between the B tuning and the A tuning...

I have noticed a difference when tuning to A, but nothing that pronounced. Nothing a little bit of amp EQ tweaking wouldn't change. Have you tuned it up to B to see how it behaves?

​​​​​​Also, have you tried wiring the bridge pickup straight to the jack? That'll at least help you figure out if it really is just a dark guitar.

Since the guitar has an FR-style trem, I haven't tried tuning it back up to B to see if it responds differently for obvious reasons... but I did however wire the bridge pickup right to the jack and it was certainly a bot brighter than what I had been experiencing up to this point. I pulled everything back out, wired in a 3-way switch, replaced the std volume with a B500K stacked volume pot for independent pickup volumes and the killswitch. No treble bleed cap this time too. And it certainly made a difference in how the guitar sounds now because it's night and day difference!

I also have a few other bits of news... to start I bought a brand new Sentient 7 to go with the Nagul, and it's getting sent right back to Duncan for replacement due to a manufacturing defect... someone wasn't paying attention when they drilled the screwhole in one of the ears, because they drilled a 2nd hole off center from whats supposed to be the original one and it oblonged the screwhole. I'm not chancing mounting it like that because either the ring mount screw or the direct mount screw the screw will strip what very little metal separates the 2 holes and make the pickup loose in the pickup route... pic attached for caca's & haha's...

And the other thing is that I took one of the 2.5" Ceramic 8 magnets I have and magnet swapped the Full Shred 7 bridge. So I am anxious to pull the Nazgul back out and try the C8 swapped FS7 and see which one I like better... I'm gonna do a quick search on here and see what results I find about ceramic swapping the FS and how people liked it or didn't before I go thru the process of pulling the Nazgul and putting the FS7 back in again...

Neck or bridge, both are super bright with little bass.

I always thought the neck was normal bass wise. Not too much, not non existent like the bridge, lol The highs are boosted, which acts like a bass cut, but it's there.

the bridge is definitely light on bass.

I bump up the bass on a pedal or the amp when I would play my full shreds. The bridge sounded tight but full, and the neck got that smooth gainy neck tone with high gain. They are still my favorite duncans.

We all hear differently? It isn't like a 59, and I only hear bass come in when it starts getting close to the strings.
 
So after a few trials and tribulations, I finally nailed it down...

First, I rewired the entire guitar. I replaced the stock 5-way with a 3-way, and replaced the single volume with a B500K stacked volume pot for independent volume controls for each pickup, removed the treble bleed cap and it worked much better. But I was still curious...

After reading a few posts here about the subject, I decided to swap the magnet magnhe Full Shred 7 bridge pickup from the original A5 to a C8. After swapping the magnet, I pulled the Nazgul back out and put the FS7B back in. I am happy to report that the FS7B is much better fitting tonally than the Nazgul. The high end now isn't as bright as the Nazgul and is a bit better balanced for the guitar and the A tuning. So the FS7 set is at home in the RG752M.

And once I get the Sentient 7 back from a warranty repair/replace, that and the Nazgul will be making its way into my Universe that is also A tuned - replaceing the DiMarzio D-Activator 7's thay currently reside in it.

So again, thanks for the insight and help everyone!
