Practicing quietly at high gain, as old conventional wisdom would put it, is an oxymoron. There was a time in the history of vacuum tube amplifiers that there's no way that you can have that fully cranked-up sound at very low volume. Various technological breakthroughs have emerged to rectify this situation, and one of these involves maintaining natural reactivity, just the thing that ARACOM Amplifiers Power Rox PRX150-Pro does.

The Power Rox PRX150-Pro is a power attenuator that makes use of a technology called "Speaker Reactance Thru" (SRT). SRT purports to deliver highly transparent power attenuation that allows the speaker to fully maintain natural reactivity, which in effect leads to that fully cranked-up tone maintained even at low volume levels. The value of being to have this capability is obvious. In terms of rehearsal or private practice time, you can enjoy tearing up your guitar with that rich tone without disturbing the neighbors while in live situations you can perform really quiet dynamics while maintaining that cranked-up sound.
