    I started a thread sometime ago about where the sweetspot was located. Many contributed with many different opinions. Bottom line is what sound best on a particular bass for you.

    I have been experimenting with adding a magnetic pickup to my Carvin AC50 piezo bass. I started off by putting the pickup right next to the neck as I definitely like more of a neck sound than a bridge sound. But it sucked in that position :rollno:

    So out came the saw and more destruction. More of a center position was better but still had the precision burp that I do not really want. So finally I made a testing system to actually test half inch by half inch to find where it sounded best.

    Two 5/8" dowells taped next to the strings. Perfect for holding the pickup the same distance away from the string as it will be when it is mounted. Then I would tape the pickup in a specific place and try it and the move and try etc. The tape is a bit of a hassle but neccesary if you want to hold the bass in normal playing position. But I also tried laying it flat without tape so that I could move it easier and hear the difference quicker.

    Man, what a difference 1/2 inch makes. :eek: I mean really. Stunning. How do you tell your luthier where to put the pickup for a custom bass? It makes such a difference.

    I finally found a spot where the precision sound mellowed but it did not get to thin or nasally with the bridge sound.

    Anyway, here is the pic: No tape as I had removed it all.
    The piece of hardwood will be a pickguard to cover the carnage.

    The position of the pickup in this pic is not where it will end up. It will be slightly north of there.

    Bass is lying flat. I moved the pickup from the extreme neck position all the way down to the bridge. I shifted the pickup 1.25" each time. This bass has black nylon flats. I think the tonal difference would be greater with rounds or other non-wrapped strings.

    It can be quite an earopener. I've used my 34" scale bass pickup testbed for over 20 years in my experimenting. A few years ago I built another for 30" scale basses.

    Looks like it sits about where a Stingray pickup might.

  10. What's up with the weird chorus/rotary organ sound?

    I liked the tone 40 seconds in best.

    Keep in mind that this is a CRUDE test. The bass was lying flat on two pillows, the pickup is temporarily wired to the cut off end of a cheap 1/4" cable. No shielding. No preamp. Straight into Audacity on my computer. No processing

    High end recording at its best :cool:

    Too bad you didn't come up with that idea before you carved huge hole in the top of your bass.
  14. Gee, I could have loaned you this for a while:

    To me, the tone at 31 seconds sounds best. It seems nice and even.

    That Westone is just plain weird.

    Where's the fun in that ? :D

    I have a reputation to maintain here. Cut first, measure later :bassist:

    However, the pickgaurd will make everything OK.

    There's going to be a pickguard over that nice flamed maple?

    What is this world coming to?

    You guys.....:eyebrow:

    The pickguard is going over the carnage and about 1/4" of the maple.

    The grief I get for revealing myself :D

    Great idea. I've wanted to try that on a fretted AC40 for a long time.
