I bought this set of tubes on recommendation of a friend of mine. It was the first time I was changing the tubes in my Bugera 333-212 and I wanted to get a specific sound. After discussing it with a few people, I decided to settle on these. They have blown me out of the water. I wasn't expecting to get the tone I wanted first time, without trying out different brands, but these Ruby's got it bang on the money.
Sound wise, these tubes keep your cleans clean, and only distort when you want them to. Your dirty tones however, they are perfect. Extremely balanced, so no worries about being too muddy or too thin sounding. Low noise at high volumes, which is perfect for me. The difference between these and the 6L6's that were in my Bugera prior to changing is astronomical. I will definitely be sticking with these tubes I can say.
Thomann as usual were fantastic. They came excellently wrapped so no worry about any damaged being caused during transit. All perfectly matched so no problems there. Quick shipping and arrival as usual. Just great all round.
