I am starting to think about replacing my 1996 M-1; I play exclusively jazz, mostly late big band, occasional small combo work. I have a Realist and an AI Coda to get me heard over the trumpets (want to replace the Realist: too prone to feedback). In smaller (unamplified) settings, I just don't like the low end of the bass; not a lot of volume or sustain. I have it strung with Superflexible Solos, probably a couple of years old. The bass has had the bridge replaced since I had it (old bridge was seriously bent!). I've been thinking about trading up to something in the $2k-$3k range, and finally did hit some shops in Chicago and tried a few things out to see if I could find something in that range that sounded enough better to make it worth the expense. None of the newer inexpensive hybrids or plys did anything for me (better, but not $2000 better!), though they were more set up for orchestral work, it seems, and there were not a lot of hybrids in stock and set up in that range. For kicks, I did grab a couple of early 50s Kays (outside of budget): they did have the sound (my wife picked up on it immediately!)... I'm starting to think about just getting the M-1 restrung and setup to tide me over until I can drop for a Kay (and it will help resale, I hope). So several questions: 1) Has any talkbassist gotten an Engelhardt to sound decent for jazz? If so, suggestions? I hate to continually experiment with strings, etc; expensive! If Engelhardt bought all the Kay designs, why won't mine sound like "that"? 2) What besides an old Kay sounds like an old Kay? It seems like old Kay's are expensive (generally $3000+, occasionally $2k-$3k).
