Hi, I chickened out of buying a sandberg P+MM (can't remember the model number) at the London guitar show last year but it was a long and painful decision. I did buy a fender instead but down solely to price. IMO you are getting more from a sandberg: active electronics, more choice for lefties, you can customise through their online spec builder. There really is loads more you can get out of it if you don't want an off the shelf fender.
You can feel the quality in them straight away, really playable neck, the one I tickled was four string with ebony fingerboard, sounded perfect. The pickups are really clear and the electronics are intuitive, I.e. it doesn't take ages of tweaking to work out what they do. I could even give it a passable slap off the big mm pickup, and I'm not a competent slap player. Set up nicely it was great, I could easily have one as my only fretted bass. I think they're excellent value on thomann, not so good value from UK shops.
