| Re: How to know if valve alignment is needed ?
The benefit you're most likely to notice from a Precision Valve Alignment is easier resonance and more evenness in all registers. Certain notes will come closer in tune, but not necessarily the ones you're expecting.
My Stomvi picc is the only horn I've ever owned that didn't benefit from a PVA and I suspect that's because Cambrass (Bob Reeve's shop) may have aligned it before US distribution. (My tech measured and said it was spot on. Another friend has the same model picc and it was in serious need of alignment, so I think somebody had Cambrass PVA mine since that is an option for Stomvi in the USA).
Your problem is where to get it done. You need a tech that understands the concept and has the right tools and material to complete the job correctly. We're not talking about blindly putting replacement felts into the trumpet. Good luck with that.
