Sounds absolutely fantastic in my Artisan 30
I bought this to give the EF86 channel on my Artisan 30 some more body and warmth compared to the stock Electro Harmonix, and I am very happy with the results. This tube brings me home in terms of the amps sonic abilities. Exactly what I was looking for. These things are subjective, but this tube brought my amp to life (I did also replace the stock sovtek EL84's with Tungsrams). The channel now sounds fuller and deeper, without loosing anything in the highs. It's still shimmery and brilliant in the top. Very clear and detailed.
