built to take a lot, but why push it? If you treat your amp well, it will treat you (and your

guitar's tone) well.

Check for loose tubes

Here's as close as you should get to being inside your amp. With the amp unplugged

and cooled off, examine the tubes to make sure they're in tight and straight. Note:

Unlike light bulbs, tubes push straight into their sockets. Never try to twist them! Also

note that some of the tubes are inside of metal sleeves. These are easy to remove for

checking the tubes. Grasp the sleeve with your fingers and depress it (it's spring-

loaded) and turn to the left (counterclockwise). Now pull it off; this may require a little

wiggling action. Remember to put the sleeve back on after you check the tube.

Make sure the power cord is tightly plugged in

This is critical at both ends of the cord. And don't use one of those 3-pin-to-2-pin

adapters unless you connect the ground lug to the outlet. Leaving the ground

disconnected isn't just cheating--it's dangerous to unground any electrical device that's

supposed to be grounded.

Let it idle before you play

If you have a few minutes to spare before you play, turn the amp on and set it to

standby so that all the parts can get warmed up and stable. Once the amp's nice and

warm (5 or 10 minutes), flip the Standby switch and get busy on your guitar.

Don't use the back of the cabinet as a storage locker

Remember, there's a speaker and glass tubes in there. Both cost money to replace

(money that's better spent on strings, picks, etc., right?). Stash your footswitch and any

other heavy and/or hard-edged stuff in a bag or a case for travel.

Clean your amp once in a while

You can use a damp cloth or one dipped in a weak solution of dishwashing detergent

and water (lots of water!) to wipe off grime, dried Pepsi, and whatever else accumulates

on the vinyl covering. Make sure the amp is unplugged first. Everything else can be

vacuumed, as long as you're gentle and use a soft-bristled brush attachment on the

vacuum hose.
