Hi everyone, Some of you may remember I posted recently about the lacquer coming off my new Jupiter 606ML. Long story short, Jupiter replcaed it under warranty. While that was all getting sorted out (it took four weeks), I admitedly didn't play as much as I had been but did play a bit on my old horn (Martin Magna) and with the same mouth piece (Bach 3C). So, I went to the shop, played a few new ones (all consecutive serial numbers), chose the one I liked best and left. I didn't sound great but put that down to lack of playing. Nearly two weeks later and I am in a world of hurt. I cannot get this thing to sound good; I cannot hit notes accurately in the staff and anything above is woeful. I will play a simple scale and miss some notes. What I'm finding is that I am fighting this horn every step of the way. My previous Jupiter was a joy to play; everything slotted beautifully right from day one. I'm going to give the shop a call, and I'm waiting to hear back from my teacher on this, but wanted to run this past you knowledgeable folks as well. I'm in no way a great player and in some respects am quite new to this (playing a few years and now at Grade 4 level, Grade 5 exam coming up later this year), but I've never had to fight like this to articulate notes. I was just putting it down to not a lot of playing for a few weeks but, two weeks later, I'm now wondering if it is possible that the intonation is so far out of whack that there is actually a problem with the horn? I hate to blame equipment but this realy doesn't seem right. Any thoughts? Thanks, Matt.
