So......not to be outdone by SteampunkScientist......
For some years, I've had a Epiphone Les Paul Classic guitar. Back in the day, I caught the "gear mod" bug and tried installing new humbucker pickups for better tone and sound. Having no idea what I was doing and having no soldering skills really hampered my efforts. Terrible connections (cold/weak solder joints) and leaving the original potentiometers, switch and cable jack always kept this guitar from sounding its best. But I had no idea until...........
Fast forward a few years. I basically turned my Epiphone into a full-blown custom-shop guitar !!
This thing sounds so badass - It's like I bought a new instrument !!
Basically, I have "gutted" the entire guitar and replaced all of the electronics from top to bottom.
What is the difference between the Gibson and the Epiphone? one might ask.
The electronics. Epiphone uses a lower grade of electronics to keep the price point low so ditch-diggers like me can feel like they own a Les Paul without laying out thousands of dollars.
I started with a matched pair of Gibson Burstbucker Pro humbuckers. I got them brand new (and on the cheap) from a local guitar shoppe.
Lately, I ordered an electronics rebuild kit with new capacitors, potentiometers, pickup selector switch, and instrument cable jack from Stewmac.
The new pots are "cleaner". Volume has a consistent, even rise from 0 to 10. Tone is clean and consistent even in the 0 setting (where things usually sound "muddy"). The new switch and cable jack just top things off with top-of-the-line SwitchCraft components.
After making the mods to the guitar, I found that I had secondary issues with my tube amp.
A rebuild kit has been ordered and I'm fired-up to get started.
Just as a gentle precaution:
One can re-wire a guitar with little or no harm - except for consideration for minor mistakes
Working on amplifiers without knowing basic safety can get you killed. Stick with the passive stuff prior to cracking into the bigger projects.
