I've owned an Epi T bird, and it was fantastic, I loved that bass, and I would argue that it's better value and just as playable as it's much more expensive relative. My mate has the Tokai bird, and once again, it's a fantastic bass, nice player, and loads of thump. I can't honestly say there's a massive difference between the two, even though the Tokai has a glued in neck, I couldn't say that made a massive difference to the tone [i]for me personally[/i].
In my experience I can highly recommend either bass.
