### ⭐⭐⭐⭐⭐ A definite upgrade
*by R***. on December 28, 2024*

I have a bass preamp that came with a fairly generic tube. That tube seemed to distort and sound farty when pushed. This tube has a much more even tone and sounds way more smooth. Theresa nice warmth and fatness to it. I don’t have a huge budget and if you’re like me, definitely buy it. Well worth the small price tag.
