Thanks for all the comments. She's up and running now, and (apart from the strings) sounds fantastic. Very powerfull Pup with a wide tone. KiOgon's circuit was very easy to install, and she is completely noiseless, even through my old Carlsboro 150w combo sitting right under halogen spots on dimmers.
I've strung her with the Roto 45 rounds I won in the raffle at the SE Bass Bash, but they are a bit bright and toppy. I'm looking to sling her with flats and I'm torn between GHS or LaBella Flats.
I don't think I can sing the praises of the neck enough. It is absolutly flawless with some very subtle flame, grain and figure that does not show in the pics. It is absolutely rock solid. I don't know whether it's because it is quarter-sawn, or has graphite stiffening rods, but it has come from hot dry California to rainy old Berkshire and has not moved an inch since stringing. Feels full and deep with the C shape, but is fast and manageable Because the truss rod nut is at the heel, the neck has to come off to adjust, so I was advised to put on a little turn and take it from there. Even the little turn I put in was too much, and have now taken all but all the tension off the rod, and the relief is just right.
The bridge is working just right, and the compensated saddles are working very well. She intonated correctly on the E and A with no adjustment, and only slightly needed on the D and G. I set her up following The Jerzy Drozd manual and have got 2mm clearance across the strings at the 20th, so a lovely low action. Most other basses move slightly overnight following any adjustment, not this one, just completely solid.
The body is so comfy its unreal. It totally has that slab look, but the arm cut especially is beautifully contoured. The finish is great and the hardware is beautiful. All the screws are slot headed, and its a really nice touch.
Sounds great, feels great, looks great.. What more could you want?
