Grid leak biasing
#11
Hi Guys

You know what they say, "Go big or go home".

Plexis don't have a balanced tone except when cranked since that is what they are optimised for. Play them quietly and they are thin and way too bright. You could probably kill people if you played a Tele through them Smile

The first 800s were okay, since they could get the cranked plexi tone at sane volumes, but still, both have the Marshall sheen of IM harshness.

Everything after that seemed to get worse in most respects, especially the VM (Vintage-Modern) with their horrible KT-66s. A friend was modifying a Marshall combo and the customer wanted KT-66s. He did the mod and tried it with the stock EL-34s. It sounded like a Marshall. Then the KTs go in and sounded like mud. It might have sounded best with one of each kind of tube, but there were no individual bias controls. The reversion to KT-66s was probably a mistake for Marshall, but it fits in with the modern fashion of muddy, compressed, tone that players seem to want at the moment, so maybe it's good for Marshall?

The only Marshalls that ever sounded good to me were modified and I think it's safe to say that Marshall is the most modified brand of amp out there.
