Me and the SeriesII didn't match. First of all I must state clearly that it was one of the finest basses that I ever had, but....
Somehow it didn't feel right in my hands. I've set it up to make it similar to the Spoiler, but somehow the Spoiler felt more natural. For most of you that must sound pretty silly, but then again dutchmen are welknown for their being silly...
I use the bass live onstage a lot (around 120 gigs every year), and I need a bass that I can use pretty fast. With a SeriesII I have so mutch sounds in my hands and so many knobs that I keep tweaking my sound during the show. The SeriesII is a bass that can make almost very possible sound you need. And with that knowledge I am always tempted in every song to adjust the bass to be perfect for that song. With the Spoiler I don't have that problem, just because it has very simple but very effective electronics. Another thing that I encountered with the Spoiler was, that it sounded more tight compared to the SeriesII which had more bottom. For live shows I prefered the tight sound of the Spoiler. For studio use the SeiesII was my favorit...
I hope this explains a litte...
