Night and Day
Got this tube awhile back and been swapping around with a few different ones to find the tone I like. I run a Tung-Sol 12AX7 in v1, the Preferred Series in v2, and Sovtek 12AX7LPS in v3 in a Peavey Valveking 212. Man with my active emgs the clear resonance and sustain are amazing. I had a JJ ECC83S in v2 and was muddy and very harsh sounding. The difference was night and day. The Preferred series is bright, natural, and clear as a bell. Buy this tube... love this tube.
