Just got my bass back from the tech today. In addition to a set up and intonation using D'Addario Slowound strings (.45-.130, with a tapered B string), I swapped out the EMG-40HZ's and had EMG-DC40's installed as previously planned and posted. I decided to keep the BTS rather than opt for replacing it with the BQS (Ace, thanks for your input there!) Straight from the tech to the rehearsal studio with the current project I'm working on, Matisse and the Playground (shameless plug: those in the GTA, ON should come check us out tonite and next Thursday at the Gypsy Co-op in Toronto, 815 Queen St. W...but I digress...) I played through my "rehearsal rig", an SWR WM 4004 amp through the WM 2x10. The difference in tone/sound was readily apparent! My bass sounds like I traded it in and bought a $5000 bass! Keep in mind that I'm running the active pickups and electronics at 18v and not the usual 9v as well. (The strings sound pretty bright but they're new; I'll spank them hard during the day to get them ready for tonight's show.) I'll be playing with the same head (plus compressor and subharmonic synth in the loop) through a SWR Goliath III 4 ohm cabinet. I'm not sure when I'm on the schedule next to play at church, but I'm looking forward to that as well! The only negative is that the volume pots had to be changed from the 500k pots from the HZ set to the 250k volume pots that came with the DCs, and the old knobs don't fit! I "borrowed" a set off of a bass we're having trouble selling at my store (a fairly nice Godin BG 4), but I have to order a set to replace them. Best idea I've had in ages...I doubt my NS2000Q5 will see much action in the near future...at least until I modify that one with an EMG-40P5 and EMG-40J in the neck and bridge positions respectively...but that's another story... FS: A pair of EMG 40HZs, slightly worn...BO wins!
