I was hoping to try these out in my wizards.. I like brighter cut tho. Are you saying they are a darker tube? how about microphonics in a high gain situation? ive heard that long plates do not fair well in high gain circuits, however, one of my wizards has them in all positions and they sound pretty darn good.. sovtec lps
They're pretty nice. They have a thick midrange that's a bit like an EI Yugo from what I remember, but way better on microphonics. The top is bright but smooth. Brighter than a regular JJ ECC83S.
