Product Reviews
This tube surprised me. It does what it's supposed to do. I used it in a Marshall 15c to tame the Red Channel (because personally I found it unusable) and it did just that. It did not change the Green Channel at all. Now, the Red channel is smoother and def more usable. Best $25.00 mod I've ever done LOL
