1k5 center biased equals most of headroom and gain. Some say it's preferred for playing solies and lead guitar. In other articles it's been said that the symmetric clipping seems much more fluid and not as harsh.
The iconic cathode follower driven hard clips the already distorted half and softens the corners of the waveshape.ġ0-39k often find places in high gain amps like Soldano, Peavey, Recto and many Marshall knock offs. This drives the preamp even more into asymmetrical clipping.ĭesigns like Laney GH or some other hot rodded Marshall mods from the 80s add a gain stage which basically clips the same signal half again so "good" high gain seem to depend on clipping one half of signal swing extensively while keeping the other half relatively clean. It's quite common to have a hot biased gain stage after a cold clipping one in Marshall amps which are clipping the same signal half as the 10k cold clipping stage. There are designs like the Fortin Cali mod or the Ceriatone Chupacabra with 820R + 680n on the cathodes of the first two gain stages.
