Would individual foam trumpet filters sound different to the full size foam filter I wonder ?


I tried them, KEVITZ, when I had the P4SS instead of the full size foam filter. The result was disappointing. In my case it was a significant loss of performance. But they are cheap to give them a try, perhaps you get better results.
