Hey there, I've been searching for a while to a tube amp to buy while I save the money. I was thinking a jvm210h with a custom Avatar 412 cab with v30's. My question is, Is the 100w head too much? I really only play at home and with a drummer and I don't think that the jvm has a pentode/triode switch for 50w. My other concern with getting a 50w is that I can get them both used for the same price on gc.com. I was looking at attenuators but I don't think it will be worth 500 extra. Thanks!

Just pull two tubes. That will drop it down to 50W.

You have to halve the impedance switch as well, right?

Another option is just to keep the master volume low and the channel volume where you need it for distortion.

] I just read an article on this, I would have to set the amp to 8 and plug it into the 4ohm jack on the amp?

No. You can't run a 4 ohm cab because you'd have to set the amp to 2 ohm. A 4 ohm 4x12 is easy to convert to 16 ohm though, then you'd run the amp at 8 ohm.

Futzing with removing tubes to get to 50W really isn't going to change much. You could probably get a bigger volume change by just finding a cabinet with Celestion Rocket 50's aboard. They're relatively inefficient and cheaper speakers that will actually produce a slightly lower volume (compared to removing tubes) from the full 100W.

Halving the volume compared to 100W would require taking the power down to around 10-15W. Probably best to just use the volume knob.

That's not the point. If the 100W costs the same as the 50W, why buy the 50W? It makes no sense at all. The 100W can be 50W with very little effort. A 50W can never become 100W.

my 100 watter's sound fine with 4x12 at home , just turn it down if it's too loud ....... even 15 watts can piss the neighbors off cranked

The volume difference between a 50 watt and a 100 watt head will be minimal (within a few db, typically). The biggest difference will be in headroom (i.e - how loud you can turn it up before the amp begins to break up).

That being said, I see no reason to buy the 50 watt version of that amp if you can get the 100 watt version for the same price, and it has a power reduction switch.

from a number standpoint, it seems really small, (and makes no sense as i am slightly familiar with electronics, no EE), but it makes a difference with my splawns, which are marshall based. for some reason the volume does change a bit, as well as the tone.
