Yeah the Ibanez was the BTB705DX. It's a solid contender, but far from ideal. What I dislike about that one is its telephonic frequency response. It has nice EMG grit, and otherwise great feel, hardware and appearance, but I think the ash wings just add too many negative elements to its tone. Ash just seems to be a really nasty wood for bass guitars, through and through. The Sadowsky was a chambered Ash body, with a bolt maple neck, and it sounds the worst out of the lot (barring the Squier, which is a joke, obviously). It appears to enhance resonance in that 160 to 200Hz area to bleh proportions.
@AStudio: I think I just very badly wanted the consensus on the Squier VMJB to be true. I thought I was doing something wrong with it (never actually had that feeling with an instrument before) hence getting it serviced and tidied up. As you say, it's obviously not worth it. What I'm talking about now with my bass buddy is that we may use it as a platform to try out different hardware, just so we can isolate what we actually want on our customs, down the track. All our current guitars have EMG-sized pickup holes, so what we may do is route Bartolini sized ones into the Squier, and try a few out, with various preamps, bridges and nuts - see where we end up!
I do use the Ibanez. It's the current studio guitar. It doesn't sound nearly as good as the NJ Beast we used on the Untruth stuff, nor the 70's chapman stick from a while back. So my search goes on!
