Summers coming up and that means a ton of gigs, and I've been concerned about my amp. I bought it used on eBay and it's 3 and a half years old, with the stock mesa tubes in it (Mesa Roadster..) Is there any way to find out how much life is left in them? I don't want to blow anything during a gig, my backup is a cube 60 ..

Edit; the seller said he had used it lightly in his basement.

He's saying that your backup shouldn't be a Roland 60 in a gig. It should be extra tubes and fuses for your Mesa.

Take one out and place it on your tongue...

I kid I kid...


Usually after two years of playing there due for a changing. Especially if you have been gigging. But as far as i know there isnt a way to test them. Usually you can tell because you loose a bit of tone and gain...

^^ ive got two of those. one i use, and the other is a back up.

You're amazing, then. I've yet to find even a basic vacum tube tester for under $300.

I have two as well, and they were free. I can't see a model number anywhere, but they look a lot like this:

Haha, thank you somebody for saying this! You can tell when tubes are starting to go because your tone will start to change. At the very least, the bias has probably drifted quite a bit over three years, so you are probably due to swap them out anyway if you've been gigging.

That's why I origionally reccomended keeping a set of spare tubes on hand.

Ya but come on, how practical is it to be changing a set of tubes during a gig? A spare amp is V. important for gigging!

Take them out, pop the new ones in? The bias will be off, but it will be in the ballpark; good enough for one gig.

If the tubes die in the middle of the gig though, they'll be damn hot....

Of course! I keep one in my gigbag. I keep an extra in my manpurse, too.

*cough

But really. Grab a jacket/strat/anything, and pull out the old ones, then plop in the new ones. I've seen a guy re-ground a Les Paul onstage at a show once; a tube swap is nothing.

Ya but it really depends on the amp, i mean if i was to change the tubes in my AC30 during a gig it would'nt exactly be practical when i could just switch amps for the sake of one gig

Yeah, but the AC30 is definitely an exception. I call it bad design. I think the people that had theirs go up in flames agree with me.

How much would it cost to retube a Roadster, with est. labor and stuff.

yes, the AC30 is a hilariously bad piece of design all throughout its years

You know how the later Silverface Bassmans were crap? Each subsequent version of the AC30 between the late 60s and the early 90s was like the Silverface Bassman to the 5F6A. In the 80s they actually redesigned the circuit for less gain to get nicer tone because of the hilariously bad valves and speakers.

Also, the chassis design is insane.

Oh, and half of the chassis was covered in the remnants from what was a huge fire in my AC30

As someone who's really into Fenders I am well aware of what happens when amps are heavily 'improved' for more headroom. Damn CBS.

Didn't CBS make the Vox amps for a while, or am I completely wrong here?

I'm not sure, I don't think so though. It was owned by Jennings originally, then JMI, then some other small-name British companies, Dallas Arbiter, and to this day Korg. Upto Korg, each succession was worse and worse! Jennings and JMI are where it's at for Vox.

The new JMI amps make me drool. The pricetags make me cry.

What I like about them is that they haven't made a single improvement to the amps; it's all there in its noisy and potentially-burning-your-house-down glory.
