I just got my first tube amp about a week ago (fender blues junior) and i was wondering if theres anything you need to do different to keep it in good shape.

let it warm up for a while before playing on it.

Don't shut off power right away after you're done playing - put it on standby to let the tubes cool down a bit first.

Blues Junior doesn't have a standby

When you switch it on, turn your guitar's volume right down, and leave the amp to warm up for a few minutes.

You don't need to let it cool down through standby, turning it off will cool it down.

There are some neat mods you can do to a blues jr to help it sound more full. Changing the bass capacitor to a .1uf will smooth the bottom end, it sounds less "boxy".
It's a fine line between clever and stupid.

why would putting it on standby, which is designed to warm up the tubes, cool them down?

you dont need to do this, in some cases its better to turn it straight off because it doesnt leave as high of voltages in the power capacitors if your planning on working on the amp.

I've actually read that using standby when you're turning off makes no difference. I do it just so I know that I've reset it for when I power back up.

how much does that cost?

AFAIK, capacitors are relatively cheap.
The mod would be free if you did it yourself but also relatively dangerous if you didn't know what you were doing

Sorry to go off topic but threadstarter, how do you like your amp? I'm on the verge of getting one myself.

Do a search for "BillM"+"blues jr" and find Bill M's site where he lists off all the cool chit you can do to the Jr. Caps are cheap, if you pay someone it may cost $50 but you certainly void your warranty.

Things to do to the Jr...

1. Bass capacitor
2. Adjust bias, either with different resistor or adding a couple trimmer pots for adj bias. The Jr, is biased hot from the factory.
3. Presence control

All pretty cheap, 3warranty voided, definitely make the Jr a helluva good amp.

It is the generally accepted truth that you should let a tube amp warm up and cool down (on standby, or not if you don't have it) don't not do it just because one guy on a guitar forum says so. Also, standby isn't designed to warm up the tubes, it just sends a lower power current through than "on" which sends through the full current (turning them off right away is supposedly bad because the change in temp is more abrupt) also, after it's done cooling, switch it from standby to on, then off. So. .

Before a jam:

warm up on standby: 1-5 min.

cool down on standby: 1-5 min


Before a show:

warm up on standby: 5-10 minutes

Cool down on standby 20-45 (don't go tossing it into a truck before then either!)

I like it, its a good amp but i dont really like how theres not a gain knob on it but otherwise its good.

Gain is just another word for volume. On your new tube amp as you increase the volume you increase your gain, the tubes start to overdrive, and you get fuzz/distorsion. If you would like a gain knob get a pedal like a TS-9.
