I don't (yet) have a reedgeek. I used to play around with reeds more than I do now. If I ever had the feeling that a reed wasn't playing well or sounding OK, my main tools have been sandpaper, emery cloth and a clipper.
I've had a PPT mpc for a couple of years but I haven't used it very often at band rehearsals or concerts because I felt I needed to practice more on it at home (which I haven't done). Whenever I played on the PPT, I'd occasionaly 'squeak' notes (on the attack), especially after playing for a while. My conclusion: more practice needed. But I recently (again) noticed how much better the PPT sounds than my standard/easy (ESM) mpc so I decided to just play the PPT as often as possible and learn how to play it without squeaking.
At a recent concert, I decided to start out with the PPT for a few solos and if things got too bad, I'd switch to the ESM. While 'warming up' the bari player - who was just filling in for our regular bari player for this one concert - heard me playing and asked me whether he could give me a tip. "Sure" I said. He then produced a Reedgeek that he'd had for a couple of weeks and scraped the flat side of my reed. I could see the stuff that was coming off. As if by magic, all the squeaks were gone and I easily played the whole concert on my PPT. I'm not saying that a razor blade or flat knife wouldn't have done the same job but I was seriously impressed! This was the same reed that played/sounded just fine on my ESM. I can only conclude that my PPT table is more sensitive to non-flat reeds than my ESM.
