for the 50s wiring ... you need to check in the wiring yrself with documents in the web.
Not sure if they did it in 2000.
The main effects shd be , the tone stays clean when vol turned down.
If you like the reaction of the pots - be happy and play.
some days ago I picked up an Epiphone GT '56
with Minihumbuckers. It is a nice Lester, sounds and plays really great.
A fast neck and fret wear near mint. Small marks - but for 21 years - cool!
It is a light one - weight relieve ?
Any owners here - what are your experiences ?
What can you...
I am convinced that in all years there were some outstanding examples made.
Your job is to find the one that is IT FOR YOU.
Most of them are "OK " some will be "dogs" . Good luck with the quest for the right one.
Another thing is the pricing... prices gone rediculous high in last years.
I love my 18 Traditional too it looks the same as yours. It rings unplugged and has sustain - btw. not weight reliefed about 4.1 kg - Very nice top flames. I swapped the BB for a set of vintage SD59N/B.
This sounds and plays awesome.
