Customer Reviews

Great sound, but mine was microphonic. Review by Nick
I really like the sound this tube gave my amp(A Laney GH50l). The amp sounded kind of loose before, with a lot of hum when I wasn't playing, but putting this in V3(the effects loop driver, I believe) cut down on the hum and tightened up the bottom end. I've tried the same tube in other amps as the phase inverter to darken the sound with much success. It had noticeable issues with microphonics when placed earlier in the signal chain, though, but that could just be the one I got. (Posted on 3/8/13)
