JP valve cluster
Posted: Sat Feb 25, 2017 11:19 pm
Joe Sellmansberger made those John Packer CC valve clusters available, and recently posted that one had been ordered and was being delivered. That was me. I was deciding between this cluster which was pricy for me at $1800 plus shipping, and another cluster from a high-end manufacturer in Europe that would have cost a few dollars less, but did not include a 5th valve. Since this one included a 5th valve, and the linkage, and Joe says that JP makes good stuff, I decided to give it a try, and since I am the "early adopter" of this cluster, I thought I'd post an initial review of the product.
First impressions: The cluster is beautiful and shiny and smooth to the touch. It has that vertical CSO York/Nirschl/Meinl type visual layout, It was buffed and cleaned off well. At first, I thought that it was lacquered, because it was so smooth and shiny, but it was just buffed well (washing it with some dish soap gave that away). The rotor cap has an engraving on it, which is neat. The rotor and linkage feels pretty solid and it is quiet.
The gold brass and nickel silver seems nice. The slides are pretty long and all slide well. The slides have all the metal and are not lapped in for the folks who want to move their slide like a trombone, but they are lined up and that is not hard to address.
The valves, likewise, are very tight. Extreme pop. Venting might be a good idea. They are as tight as anything I've come across. The ports are very open. There are some small bumps, but not much.
One thing that is different about this cluster and many that I have seen is that the bends do not appear to be ovalized at all. Many Chinese, (and some American) products have oval bends, but these look nice and round.
I will update this post as time goes on, and especially after I have the cluster mounted to a tuba and can try it out for a while.
