Mesas don't come with an adjustable bias pot so no. And every Mesa branded tube should bias right without need for adjustment. You just need to get the bias mod done if you want to mess around with out of spec power tubes.

need to bias from factory?

no

can it be beneficial to your perceived tone?

maybe

i hear mesa's are usually quite cold biased from the factory. heating up the power section might unlock a new palette of tones, annoy you with noise, or make no difference to you depending on your needs and uses.

also an amp's biasing may 'drift' after being set at the factory, regular rebiasing is recommended by many experts; but the only people following that advice are on tour with an amp tech to do it for them anyway (they also always play with fresh strings and picks ALL the time too)

i know many people who immediately take their fender or mesa and rebias it hot for their purposes, but some people don't like it

that is right, mesa has those tubes you need to order. and to bias a mesa you need that mod too, the kinda like the one grisky had...

This post is full of truth. Apart from 'they always play with fresh strings ' bit Tom Waits always plays with old strings.

You don't have to and in your case you can't change it but it's something I would ALWAYS check. You never know, your amp could have been built on a Friday afternoon - or Monday morning. Better to be safe than sorry.
