Not had it cranked yet but at low volumes I can tell it has a very wide range of sounds. Individual level controls for both halves of the pick up give a lot of flexibility.
It grunts, and sparkles. I like it a lot.
Solved - Thanks man. Pulling the strap over the rear hump took away say 50% of the dive. But by doing so it also shortened the strap which brought the bass up a little and now my right forearm rests beautifully on the back of the bass. It's not only very comfortable, but the weight of the arm kills the last bit of imbalance!
Thank you @pedfor all the work you've put into this project, and indeed into all things Basschat. I don't exaggerate when I say my life is a better place for this place.
It is a winner. Straight out the box, no fettling, plays beautifully, sounds fresh and bright, or throaty depending on how you wind your knobs.
Don't know what the two volume controls are all about as there's only one pick up but it all works very well.
