Hey,
I just bought a JCM 900 100W/50W amp to use in my band. Buut when I bring it home, and I able to switch it to 50W and play it at a low volume, or will that ruin the valves? I've heard it does that. Just need to know for sure. If needed, i'm running it through a Marshall JCM 900 1960a cabinet.
Thanks,
Nick

Running it at lower volume is no problem at all. Enjoy your new amp.

The difference between 100W and 50W won't even really matter at bedroom volumes. Lukily for you, this isn't 1966 and amps have master volumes. You'll be fine, just simply turn the volume down like you would with any other piece of electronics.

Also, a smaller cab could help with any volume concerns.

That's all you need to know.

Valve amps do sound different turned up (read: different, not necessarily better),

But actually you wear valves out faster having it turned up so technically better for the amp having it turned down, it probably only uses two valves in 50W mode so be careful to keep an eye on those two dying before the other two

50W mode on a JCM900 is there so you can get power tube distortion at slightly lower volumes. We are still talking about stage levels alongside a drummer though. At low volume it does jack shit.
