I can't believe it worked on the first try. I've had a BTS control sitting in my closet ever since I got the original EMG HZs taken out of my Schecter Stiletto Elite-4. This was done when I had ZERO knowledge of onboard electronics and not so great tonal knowledge. I had augmented the bass before (a month ago) with another 9V battery bringing it to 18V. It didn't do much at the time. It did a lot more once the job was done. Figuring out how to wire everything together and soldering with a Cold Heat kit is not the easiest thing to do. By the grace of God, I was able to wire everything up, align the knobs, and plug in. It sounds excellent. The output is hotter (not distorted), the finger tone is a little bit more touchy, and the tonal variations ,for slap especially, is incredible. Trying to blend the pickups was hard before I added the control. Now the volume stays pretty much even and it's a lot easier to switch between tones! All in all, an excellent addition to my bass. I didn't even have to pay anything for it since it came with the bass a year ago. I wish I had the BQC Control with variable mid, but considering the BTS cost me nothing, I'm EXTREMELY happy. -Eric. P.S. - If anyone wants pictures of the installation and/or sound clips, I can post them. Just have to find a hosting site.
