Yes... but if you're not really that bothered about it, you can just pop it in and go.

it wont also mess up the tone completely? i heard that it will ruin your tone, and make the tubes last a month.

Preamp or power amp valves?

Just because one has tone suck it doesn't mean one's tone sucks.

You never need to bias preamp tube.

It'll probably change your tone, but it won't mess it up... Also not biasing your power tubes will take some life off, but not you're not looking at taking 10 or 20 months off a tube's life.

the spidervalve is cool.

No it doesn't. Read all the way through.

TS- according to Google, Line 6 recommends that you bias your amp.

I've played my amp with a bias as low as 22ma and as hot as 35ma and in my experience it was a bit lackluster when cold, and a bit 'warbly' and muddy when too hot. 6L6 tubes should run higher than that I think optimally. I've never biased a 6L6 amp.

I also have no idea where the bias trim pot is on your amp, but if you have to go inside it can very dangerous. Like deadly and shit.

If you don't bias I don't think it will be the end of the world.

Biasing is almost never 100% necessary. Certain amps aren't very stable or you might get a set of out of spec tubes but unless they're redplating, you don't need to bias. Tonal changes are minimal, especially if you aren't cranking the amp.
