Fischer Ischell sent me this pickup to audition and it will make the rounds of a few Talkbass contributors who have agreed to check it out over the next month or two. Fischer asked that the pickup be returned after 5 auditions to insure it is still working as intended. I'll leave a few impressions now, and some in a couple more days as I have more experience working with the pickup. Might be worth mentioning that I have no experience using other body mounted pickups such as the Schertler Dyn-B and Ehrlund, but a couple of the testers do, so it will be interesting to hear their thoughts. It does take a little time to find the optimal location on the top of the bass. When working with it at home on my "A" bass, position #1 as in the brochure, under the treble bridge foot, seemed to be the best, although I didn't take the time to change positions more than 5 or 6 times, so it's possible there is a better position somewhere on the top. In this position, I got a pretty even pizz sound across strings, although the E was a bit weaker in volume. The sound has a different character to the sound of the bridge type pickups I've always used, and I would have to say, it is less electronic, "pickup-y" sounding, and more faithful to the acoustic character of the instrument. The arco response is excellent, without the harshness of most piezo bridge pickups I've used. Very natural sounding. I kind of summed up this first session with it thinking that "I could use this pickup". I'll stop here until I've worked with it some more in a gigging situation. EDIT...And I used it all night on New Years Eve. My "B" bass liked it best in position #1, too. My comments above still apply. Playing with grand piano, tenor sax and vocalist, the sound of the bass melted into the mix with less edge and clarity than bridge pickups, kind of like playing without amplification. When soloing, I really noticed the acoustic sound I was getting compared to other pickups. I feel I got the best response on the G and D strings. The volume of the E and A strings seems to be a little lower, but I'm not sure it actually is as I'm used to the brighter punch that bridge pickups create. Arco was natural sounding and excellent. I'll use it once again on Saturday and post my final impressions before I send it on.
