this might just be me as a player and preferences but ive seen online really mixed syos opinions. I use a spark, and its an ok mouthpiece. but some reason my intonation sucks. everything is sharp no matter how much i adjust and the low notes on my horn sound super thinned out. but when i use just some low range c.w fobe mouthpiece from my school everything changes, my sound is clearer, bigger, a lot darker but what do i expect from some step up classic mouthpiece. i just wanted to know if anyone felt the same abt syos
