I am looking for a backup or eventual even replacement for my main bass which is a 28,6" scale length black Ibanez Mikro (one of the old ones with basswood body), on which I have replaced the stock pickups with a pair of P/J EMG Geezer Butler and the stock bridge with a cheap black classic Fender stykle one. I first had the weathered black Mikro in mind as backup/replacement for the bass I currently use as my main, but then after I watched a demo video of the new Jackson Minion basses, which shares many of the same features and specs as the Mikro, including the 26,6" scale length, decided for a green Minion bass instead. But in the meantime another option has popped up, namely the now discontinued ESP Ltd B-4 JR. The thing is though I don't know much about the ESP bass. What I do know is that it got 24 frets vs. the Minion's and Mikro's just 22, but on the other hand only got a single P pickup vs. the other two alternative's P/J pickup configuration, finally it got ever so slightly shorter scale lenghth namely 28,5" vs the 28,6". However wouldn't really be any major deal breaker for me having to eventually add and extra pickup myself to the ESP, and the 2 extra frets and generally more accessible neck high up of the ESP would be a nice feature for me. What I really am most interested in knowing is how the overall quality of the ESP Ltd B-4 JR compares to the two other alternatives I got for a sub short scale bass in the ball park of 28" scale length, the Minion and the Mikro, including stabillity of the neck (not so much regarding the quality of the electronics (pickups e.t.c) and hardware, more in terms of the quality of the wood and fret work)?
