So gave it 24 hours to acclimatise, cold and dry air here. Set it up tonight (~1/4 turn on each truss rod) and got the neck relief nice and low. Then dropped the action a fair bit.. wow, nice guitar to set up, came up really well. Then finally plugged it in (ADA MB1 > desk > studio monitors), love the sound(s), and now lots of experimenting to do...
Only complaint is it falls away to the left (neck heavy), Mica at Alembic has been making some suggestions to help, apparently SC models are neck heavy. So will maybe try a 4" wide strap with suede which should help. I played it at rehearsal tonight (I'm usually the lead guitarist LoL), loved it, so nice to play and sounds so great. Although my fingers are very sore, but they will adapt. It's a very responsive instrument, which really suits my stage of playing, captures all the nuances in both left and right hand. I need to get some Mullard long plates for the MB1, I recon they will go well with this bass.
