« Lamp warm, rounded sound. »Published on 10/10/11 at 19:36
Predominance in the lower mids sound and serious, this tube will heat a roundness and its too bright or garish.
I use it instead of the cathode follower (drive of reverb and tone stack) sometimes on a floor or clean crunch to bring him round if I find it too loud.
A Good tube which I never had a problem with microphonics by some easily lead against the breath on the floors of distortion.
I use this for jazz, blues, or to "darken" the sound of an amp with too high treble that will easily screaming.
However I strongly discourages the amp "dark" or if you want a sharp distortion, because the lamp quickly sift the aggressiveness of a distortion.
Also I would not recommend to mount a receiver complete with lamps that since this causes a big loss of momentum and shine.
Finally a good lamp, but used in specific situations.
