NOS RFT 12ax7
I’ve been struggling with my Blackstar Artist 15 for over a year now trying to dial it in. The tone was dull, bright, ragged and lifeless. I tried different speakers and that helped but it still wasn't right. I knew that the amp had “tone” locked away somewhere and I was determined to unleash it. Now I’ve experimented with various NOS tubes in the past with other amps but for some reason I completely forgot about how much they affected the tone, especially in V1. So I started reading reviews of various NOS tubes and had my mind set on a GE Longplate 12ax7 but then I came across reviews of the RFT 12ax7. After reading reviews for 2 weeks, I decided to give one a shot. My Artist 15 came loaded with cheap Chinese Ruby Tubes that got awful reviews. They we described as bright and lifeless which is EXACTLY what I was hearing. So I got the RFT and plopped it into V1 and.....WOW!!!! Unbelievable! I finally got the tone that I had been trying to get from this amp. The difference in tone is very dramatic. The tone is now smooth, rich, musical and to my surprise, very percussive. That one little change transformed this amp into some that can now compete with boutique amps that sell for thousands of dollars. No joke. Can't wait to change out the other tubes now. Will try another RFT 12ax7 and a pair of Winged C 6l6s. This amp gets good reviews with the cheap tubes. Can only imagine what kind of reviews it would get with good tubes!
