Hi all
I was wondering if somebody had experience in upgrading the speakers in the Roland JC40? I love the cleans on it but when I use user distortion pedals on it that a high frequency fizz that I cannot remove. For some reason though OD pedals are ok.
So yeah any suggestion would help
You can get some darker speakers, but that will affect the sparkling 4kHz+ cleans. I'd honestly try hanging an average thickness bath towel over the speakers and see if that does it for you. If not, an ET10 might do the trick. Wide cloth dust covers tend to sound better with distortion. Maybe try just one with a towel over the other stock speaker?
