I'll preface what I'm about to say by saying I'm a huge MM fan - I love my Sterling HH and have both versions of Big Al which I will never sell. I'm probably going to get in trouble but I tried a Caprice yesterday and was totally underwhelmed (not helped that for some reason Caprice's are ridiculously expensive in Australia). Lined up next to a Fender Elite P bass (which costs the same here) I couldn't believe how much lower the output was. I also thought the tone was too aggressive and abrasive (personal choice admittedly) and couldn't be "softened" and the neck dive annoying enough for the cost. The neck is also deeper/fatter front to back than all of my above mentioned MM Basses so just didn't feel right.
I know the Big Al is definitely not everyone's cup of tea, but the passive tones (especially out of the SSS), are much more rounded and I find you have much more scope to alter the tones to your requirements compared to the Caprice. I may look weird standing on stage with a Big Al -I get it - it's not everyone's cup of tea aesthetically - but the scope, output, neck and tones when compared to the Caprice has curtailed my GAS for a Caprice.
