Here's what I've done with my PCK.

- Extended valve slides on 3,4,5 - this way there is less of a bore gap when they are pulled.

- Reversed 3rd slide coming out of valve - 3rd usually needs to be pretty far out, and E-flats and A-flats tended to pop too much. Reversing the slide made the front of the notes respond with the same ease as the rest of the notes around them.

- Added Saturn water key to mainslide

- unsoldered 1/3 of the leadpipe from the bell, just to quicken up the response.

Regarding the 4th valve that Bloke mentioned...my slides didn't have slide sleeves, so I bought them, and it did help out. Most PCKs have a return slide that has 2, 90 degrees bends directly before it reenters the 4th valves, and then another 90 bend in the valve itself. All those turns happen within about 3-4 inches. The PCKs without the bends have an amazing 4th valve slotting and an even better low register. Same with some of the 5th valves.

The G at the top of the staff. I currently use a custom GW and have no issues with that pitch, but it took some time to find a mouthpiece. The other mouthpiece that worked well was a modified 30H copy from Kanstul that also did not have the pitch issues on that G. Neither mouthpiece messed with other notes that much.

So I guess you will mention the flat 5th partial (2nd valve - Eb) on the JP CC :?:

'Tis true. When I spoke with Joe about this Packer, he spent almost an hour on the phone with me answering all my silly questions, and was very detailed about the intonation quirks... and even offered alternate fingerings that worked for him! I'm very grateful to have such honesty while dealing with a seller!

New Meinl Weston tuba prices just keep going up and up...the 'Buffet' factor?
