What about power tubes that breakup earlier? Would that solve some of the brittleness at lower volumes?

There's just no way around an attenuator with a plexi style amp unless you get a master volume mod and then is it really a plexi style amp anymore? I love the THD Hot Plate with mine. Of course there are many more expensive choices, but the THD works very well in my opinion.

Congrats!
I love my JTM45 man. 30 watts of Plexi bliss. Used it tonight at a gig and it slayed. The band was just laughing at how great it sounds.
Stratocaster, wah, tuner, Keeley Baked TS-9, Fulldrive MOSFET, Carbon Copy, CE-5, JTM45, Hermida ported 2x12 with Vintage 30's. Perfection. :rock:


I was on the fence between the JTM45 and the 1987x. Gary Moore's Still Got the Blues tone was tipping me toward the JTM45, but the tone in the vid below sold me on the 1987.

 
I've never played a Plexi circuit amp that didn't leave me wishing it had a master volume!
 
Most of the amps I use the most of the about 20 here have no master. Personally I feel the master makes for a much weaker thinner tone. It obviously kills dynamics. Not that I do not use amps with a master .... I just prefer the others.

OR, you can man up, dime everything, and feel the magic :rock:

If you want to puss out though ;) , the Alex is the best attenuator that I've tried, and I've tried most of them except the Faustine and Rockcrusher. The big difference that I found with the Alex is that it retains the dynamic feel better than any of the others IMO.

If you install a PPIMV it sure is still a Plexi. I personally prefer them to the attenuators I've played, but I haven't played every attenuator out there ...

The 1987x RI amps were made to be a little more aggressive than the original ones which will help some with the volume-gain combination but you are still likely going to need some form of lowering the volume.

I don't know the "mechanics" behind a PPIMV. Are the output section/power tubes working just as hard in that scenario as they are with a dimed plexi through an attenuator, assuming say a 50% volume/db reduction from an unaffected state? Are the feel, sag, and dynamic response kept? If they are, then I would agree with you, if they aren't, I'm going with Curt.
 
After you play it, be sure to try a real JMP and then shit yourself when you realize the difference.

Also, MV on a JMP doesn't stop making it a JMP. An attenuater colors the tone just as much. Its the roar that makes the amp.

No the transformer & powertubes are not working hard. It is a master after the phase inverter before the rest of the power section. The only way to get the powertubes & transformer working is to have enough of a signal put into them. You can turn up the master loud enough to do this - but it is going to be very loud.

To be honest in my opinion any way you lower the volume - MV / PPIMV / attenuator kind of sucks..... But it is practical.
