What happened? Same thing that ends up killing all bands sooner or later - the inability to coordinate rehearsal schedules....
Just kidding... Actually, the drummer went through a rather nasty divorce (is there any other kind?) & bowed out, & then the lead guitarist got married to a gal with 3 young kids, 2 of them having special needs, so his available leisure time shrank a whole bunch.
My singer/rhythm guitarist & I found a
great drummer on CL, and never replaced the 2nd guitarist, so it's a 3-piece original metal band now, and I'm using my Moog Taurus pedals quite a bit more now to help fill things out. My bass lines have gotten busier as a result, and I'm enjoying the challenge of keeping it tasty & supportive, yet more upfront as well. We've been woodshedding for almost a year, and are (more than) ready to take it out of the garage & into the clubs.
My NS-4 is still my numero uno, but like you, it's great to have multiple Spector options to choose from.
