Re: Epiphone Casino
I have a Casino that I picked up several years ago. They're one of the better Epiphone offerings out at the moment, though I haven't tried any of the new Century series semi/hollows..
I find it plays really well from stock. The stock p90's are decent but I put a pair of GFS vintage overwound pups in it with black covers, and changed the scratch plate to black also (similar to OP). I then also changed the stock pots to CTS 250k - its now just running a single master volume and single master tone, via the 3-way switch.
I think the pots are a worthwhile upgrade, the pickups are to taste - but be wary that many other dogear p90's don't quite fit with the casino. The pole spacing is different to generic p90's and it varies between the neck and bridge pup. The GFS ones are one of the few that align.
My next change will be to 500k pots - if I can be bothered.. It sounds quite good as it is.
I find the bridge and tail piece to be ok, but there is a bit of buzz to it when running heavier strings so this may be another upgrade if I find the motivation..
Lastly, I've been running 12-52 strings with a wound 3rd (G) string, and have it detuned a tone (D, G, C, F, A, D) - sounds so moody and smooth. I dig it in this config.
