Mockingbirds are the best looking bass in my opinion. Always wanted one and found an excuse to buy. I picked up a new 5-string Mockingbird Plus on sale for $280 w/case when I was trying out for a new band (they claimed to play in C standard and I though up-tuning half a step on a 5 was better than down-tuning two whole steps on a 4). Here is my opinion.
Ergonomics were straight out of Hell. I moved the strap buttons to reduce the dive, but could not eliminate the dive. It's like BC Rich didn't even make an attempt as a comfortable bass. Also rode funny on the shoulder. I usually rest my thumb on the middle pickup, but I found myself almost always resting on the bridge pickup making the fretting reach longer - which at 5'7" playing a 35" scale bass wasn't exactly ideal.
Neck needed some serious truss rod tweaking, but otherwise was quite nice.
Finish was beautiful. Weight was lighter than I expected. Given the light body, the neck dive problem only made more sense. And, the combination of shape and light body only made less sense.
Pickups were l.....a.....m......e. No balls. The tone from the dual P pickups was round and warm, but the pickups weren't just not hot, they were downright cold. Any volume or gain was going to come from somewhere other than the bass. Just not a bass you could swap in/out without changing all the amp settings. That kinda bothered me because I'm a bit of a set it and forget it kind of guy.
All in all, you have this beautiful hard rock looking bass that's hard to comfortably rock out on and puts out a sound more suitable for walking bass lines in country or classic rock than punching out tight riffs in metal.
First bass I traded back in. And, I still can't help but pine for one. Someday I'll win the lottery and pick up a vintage USA and be happy....maybe...
