I have been playing Epiphones for the last 10 years (LP Standard and Sheraton II) but now want to move up to a Japanese Tokai ES. Having looked around the internet I am a bit confused by the various models. There seems to be ES100, ES110, ES120, ES130 and ES135. Could someone please explain the differences or point me to a site that does this. I live in the UK so would like to know what models are available here. Thanks.
