Hey everyone, I have a question about the valve springs on my Bach Strad. The action on my valves are not as quick as I would like them to be. They just feel sluggish and the response isn't quite there. My question is will a simple valve spring replacement do the job or should I send it out to a repair shop? I had my horn overhauled about ten years ago, but I am not sure if they replaced the springs. My 12b was completely overhauled by Dr. Valves (they did an absolutely incredible job BTW) and the action is incredible, however, I don't want to send it to him or another shop unless I really need to. I know this maybe difficult to address since all horns are different and my horn may have another issue contributing to the less then quick action, however, I thought I'd ask anyway. Any feedback on this would be greatly appreciated. THANKS!!!
