Ratings & Reviews
This tube is amazing! Sounds big, fat, rich in midrange and has enough gain to not make it sound too fizzy. Love it on V1 position in my Bogner Alchemist. I think this tube can be a great repleacement for NOS sound, I'm sparing my NOS Tesla Ecc83 and Mullard Ecc83 for gigs and studio only so I gave this tube a try for a practicing purposes and I gotta say it comes really really close to the NOS sound. It's very cheap and I gave it a try and I was blown away what sound I got for such little money!
