Hi everybody, I have a classic '57 neck pickup on my Gibson ES175D, year 1988, that sounds incredibly "thin" and metallic, and not "fat" as on the other Gibson 175 I tried out. I purchased the guitar second hand, but neither me, not the previous owner (he told me so), we have never changed the original pickups. What can be the reason? Do you think that I should replace the pickup? A photo is attached

Hi there and welcome.

Firstly, according to Gibson's website, the '57 Classic pickup wasn't introduced until 1992; so if your guitar is from '88 and has the original p-ups then it can't be a '57 Classic.

That serial number was used on the majority of Gibson's humbuckers for decades. It was the original Pat No. for the PAF's (actually it was for the trapeze tailpiece - but that's another story).

As to the problem; have you checked the wiring from the p-up to the pots and switch? It might simply be a dodgy bit of soldering. It could be a faulty potentiometer. Check the output from the p-up if you can - to narrow down where the problem originates. Once you know whether the problem lies with the p-up or any other part of the wiring harness it will become easier to trace the cause of the problem

Good luck!

P.

Thank you very much for your help. In any case I haven't noticed any reduction in volume, I imagine that if the reason was a dodgy bit of soldering or a faulty potentiometer, also the output volume should be low. By the way I will follow your indications. Concerning my pickup, do you have any idea on what model it is? Should it be better or sound nicely than the classic 57?

You can look at the original patent here: http://www.google.co...ved=0CDQQ6AEwAA

As you will see this was originally Gibson's patent for the combined bridge & Tailpiece as used on the early LPs and ES-295s. It has nothing to do with PUs. My understanding is Gibson uses this patent number on PUs as a way of preventing people from copying the design, but I have no idea if that works or not.

My guess is that someone's been inside the pup before. The clumsy soldering job seems to guide my thoughts ...

Problem solved! It was a faulty potentiometer (thank you Pippy for your support). Now it works fine. BTW, I am curious to know exactly what P-UP model my guitar mounts up. I think that this substantially is the same technology of PAF P-UPs, maybe is a "T bucker", but I haven't removed the pickup cover and I can't verify.
Detailed infos on PAF pickups are here: http://home.provide.net/~cfh/paf.html
