I've been playing 5 strings since '88. I traded an amp for a Steinberger Spirit 5 string years ago. I disliked the stock pickups...too dark, weak and didn't pick up the B or G string well. I routed it for soapbars, and not wanting to sink much into this "project bass" I tried a few inexpensive pickups, but ended up using Mighty Mites from my Pro-tone Squier, with the higher output pickup in the treble position. I didn't care for the passive tone. I've used active basses since the late 70's when I built a preamp for my 64 P bass. I built a couple to squeeze into this bass, but wasn't happy. I tried a couple three band EQ's, including one with a sweepable mid, but just wasn't happy. I replaced the three band with sweepable mids in my MM Stingray knockoff I built with a two band Stingray preamp I built and really love it. While not as versatile as the three band, what it does is just great. So I thought, why not a Stingray preamp in the Spirit? I was even prepared to route for a MM pickup and fill in the soapbar routes. I put the preamp in yesterday. It works with the MMite soapbars and 500k blend pot well. I think it's what I have been looking for. The Stingray 2 band is an interesting preamp. The treble is sort of boost and cut, but boost in a pretty passive way, with the boost just being a cap in parallel with a large input series resistor. Rather shallow, but effective. The cut with the treble is feedback type using a small cap from output to the inverting input. The bass is an active boost. It's sort of a preamp voiced for passive bass lovers. It adds what an otherwise sort of thin, wide aperture pickup lacks, and a little more versatility than a passive treble cut. I can see why it's so loved. Add that it's pretty quiet and with the original op amp, sucks next to no current from the battery. I have practice tomorrow night. We'll see how this bass works. With the old preamp I had too much high end noise for our church setting in the PA.
