RFT 12ax7-Blackstar Artist 15
I recently wrote a review about how good an NOS RFT 12ax7 sounded in v1 of my Blackstar Artist 15. Well I decided that I wanted to try a different tube in the PI slot so I bought a new issue Tung Sol 12ax7. This tube is bright with a lot of gain and really didn't like impress me. Well today I decided to swap the v1 and PI. Now I have the RFT in the PI and the Tung Sol in V1. I am completely f*cking blown away! The tone of this amp has been completely UNLEASHED. It sound and FEELS absolutely beautiful. Wow!!!! My tone now very clear, warm, smooth, and percussive. Very musical compared to the stock, out of the box tone. Also impressed with the super tight and clear bottom. Anyone that buys this amp will never experience its full tonal capabilities until they change the tubes!
