Pictures added - 1964 jag with reinstalled electronic, guitar doesn´t sound right

Need help from offset geeks! I have posted here post about 65 neck pickup that I installed into my 64 jag. It still doesn´t sound right. Guitar still has piercing tone, too much high frequencies and lack of mid frequencies. I tried to block of the piercing frequencies both ways (amp and on guitar pot), neither way has the result I want. If go down with high frequencies, the sounds is too dull.
I still beleive that this jag has great potential, it is incredibly resonant and balanced allover the fretboard.

Summary: body and neck original, route filled with plastic material around the neck pickup. There is also another route along the pickups filled in with wood. I switched master bridge for some classical bridge (not sure production or year, but it helped to get a bit thicker tone). Repaired body crack next to neck heal. The electronics was reinstalled before I bought it, not everything is original. Pots in main circuit seem to be original, see the picture. Neck pickup is black bottom from 65. (With resistance of 6.2ohm)
Guitar was sanded. Weight is 7.94 pounds

Body:
This jag has a lot of wear and went through very hard life obviously, some dents in wood are filled with plastic, see pics. Also, 4 holes for the neck-body joint are bit more loose than you would expect, maybe this can have impact on sound..

Other non original / missing parts:
Some parts are non-original, bridge, pickguard, whammy bar, decal, most of tuners, some dots were prolly changed for new, no mute, Missing metal plate under the pickguard.

Electronics
before I bought the jag, ilectronics was completely taken out and rewired from scratch. Some wires seem to go different ways (are connected to diifferent places) than in original wiring. I am not expert for electronics, just what from I see when I look the wires. Eg. the lead wire from neck pickup goes to the switch on rythm circuit. On the other hand, both circuits switching works normally, you can get that darker tone at the rythm circuit and bright tones at the lead circuit pickups options. Strangl switch works too. Pots, cap and resistor at the lead circuit look original to me. The pots of the rythm circuit seem to be non original. to me. Neck pickup from May 1965, Bridge pickup some newer reissue.

Guitar sounds really well acoustically when not plugged in to amp (better than most pre-cbs offsets I have played). Neck has absolutely great feel.

Maybe a change in electronics, different capacitor, pots, or wiring would help?

I will post here some pics later. Is it possible to post here sound file too?

does adjusting the pickup height make any difference?

I was trying that too, difference is jusrt little bit, far from to be sufficient.

So, i opened the pots in main circuit, they seem to be original, 6427 as a part of the code of both pickups, see the pics.

Routes inside: route between neck and neck pickup is filled with plastics. The other route is filled with wood.

What's happening to this body ? It's the questionmark ... why repair like this the cavity, holes and neck pocket wall. The Previous life of your guitar was tormented, she goes on the road...

Oups, humbucker was added at a time and the 2 holes in front of the tremolo ... a tunomatic style bridge was use may be...

Two holes between bridge tremolo and bridge are after the buzz stopper. I took buzz stop away. Yes,you are rught, guitar was abused in past, that's what the previous owner told me. I don't think that the lack of mids and too many hogh piercing frequencies are result of repaired body cracks(the guitar is balanced all over the fretboard and absolutely great tone and feel with fuzz face). It be electronics, maybe incorrectly installed after the reset?

You're right buzztop mounting holes, i think you'll have to scrute all the components of your wiring to find the multiple possible guilty and sheme for your existing electro assembly, i think it is a simple resolution.

When you say 65 Pickup is that a Pure Vintage reissue or genuine vintage 65? Have you checked the switches are working properly?

My experience is that mid 60's Jag pickups can be very toppy and vary a lot. I had a '68 (so a bit later) and they had very thin pickups. The 1965s I owned less so.

So assuming the electrics are OK it could just be that is how they are. Jags are bright, percussive guitars.

Options include:

250k or 500k pots instead of 1meg
different wound pups to your spec

I've also found from my experience I tamed the sound by using a compressor which reduces the plinkyness and tames the high end.

if the tone is too shrill specifically when the neck pickup is engaged, it could be that its wound/installed in a way that its out of phase with the bridge, which would lead to a shrill, trebly quacky type tone.

Rotating the pickup or flipping the positions of the hot and ground wires would be a relatively quick way to tell if this is the problem.

More info about my pickup from 1965 here in another thread. Btw it is still black bottom, so probably manually wound pickup...?

Guys, it was really out of phase, now guitar plays right!! Maybe I will still go through the electronic circuit with my tech. Btw pots seem to be original, right? See pics above.
