As I have stated before about JP instruments,
The quality of the piston valve blocks, the quality of the rotary valves, the fit between inside and outside slide tubes, and so on is all good from that factory…
… but if I buy straight from the factory (unbranded, and not to JP’s quality specs) to avoid JP’s markup, I don’t get the quality of assembly of those quality parts. Thus: I have to fix stuff. Again, I am lazy. I don’t like fixing new stuff - particularly since it’s quite a challenge to keep new stuff looking new after it has been fixed.
Dan Schultz enjoys showing that - sometimes - the stop arms on the rotors on JP tuba-sized instruments don’t fit tight against the valve stems, but – then again - neither do some of the German-made stop arms, and pressing down some of the German stop arms onto their stems still results in a noise, until the center screw is tightened down.
Were I building some typical three-quarter inch bore piston C tuba with a fifth rotor, I would be extremely happy slapping a JP C valve set on it, as long as the bugle that I chose didn’t suck…
… and the same goes for JP’s 19.5mm and 20mm rotary valvesets - as well as their linkage.
Were I in love with a PT-15 version of a B&S F tuba, I would play JP’s… there just isn’t any difference in build quality. … but I personally prefer the old handmade sheet metal version of a PT-9 with five bore sizes, six rotors, and a smaller bell throat, so…
I’ve also not played a better 19 inch bell compensating E-flat…but I already have one that features a goofy detachable recording bell - which is perfect for early jazz…and I’m not going to be owning two compensating E-flat tubas, so…
Finally, I sort of wish I spent more time playing the JP copy of the Czech-made Arion compact model B-flat. it’s better than the original, and - even though the Holton B-flat that I built for myself features a different bell diameter and a different bore size – the two instruments play very similarly, and don’t sound that much different. Further, the JP instrument discussed in this paragraph offers really great intonation. I might add a fifth rotor to it to make it chromatic, but it would’ve been a lot easier to buy one of these for myself than to have built the Holton.
… and I’ve only mentioned the three tubas that could’ve possibly been of interest to me for personal ownership, and none of the rest of them that they make.
People are going nuts for their euphonium‘s… For me personally, they’re not what I need but who the hell am I ? (nothing more than a doubler)
I just don’t go for toys like 18th century style pre-tuba instruments, obsolete-style tubas, tubas that are sort of interesting and fun to play for a few minutes - but not usable (due to intonation), miniaturized instruments, I’ve gotten over the helicon thing, and so on, and/but I am waiting for JP to expand their line more towards American tastes – as I expressed in an earlier post in this thread.
OK… Commercial over.
Back to non-commercial (but just as biased) discussion.
