I have a very nice Epiphone IBJL Casino but am looking at a Gibson ES-135 P90 (on eBay). I am guessing there isn't going to be much difference tonally between the 2? The IBJL has Gibson USA electronics. I've never played an ES-135 but am going to assume it has a 50's fat neck and the pickups are P90's and not the P100's right? Honestly, I don't know why I am getting the itch to buy, but those single cutaway Gibsons just have a way of getting to me. I've owned 2 ES-137's (one cherryburst one triburst) and sold them both because neither held a candle to my ES-335. I am guessing the ES-135 is going to have the same feel (stiff). Do you think I am going to find the same thing comparing it to my Casino once I get the ES-135 in my hands?
