Hey guys, I'm about to order my first Dingwall. Still thinking if it's gonna be an ABZ6 in Natural finish or an AB1-5 string in Ferrari yellow, both would come with a wenge/wenge fretboard-neck combo. Both would have almost the same price tag. The thing is that I'm considering adding a Glockenklang 2 band pre amp, but it costs $300 more, and my budget is kinda tight, let's say that I would like to keep this around the $2.5 mark, and with the preamp my budget would be considerably surpassed, so my question to all Dingwall AB owners out there is this: Does the preamp make a huge difference tone and permorfance-wise? Is it worth it? I own passive and active basses, I'm aware of the differences between one and another, I just would like to know the opinion on this particular pre from those that have been using it on their AB Dingwalls for a while. I've heard and read that passive AB's don't even sound that "passive" as one could think. Hope I can get some input from the TB Dingwall community. Thanks a lot!
