If you want to get the best possible sound from your tube amp, then you need an AmpRX Backline voltage attenuator. All tube amps (especially vintage tube amps) are designed to run at an optimal voltage, and standard 120V/AC wall current is typically too high for vintage tube amps, as well as some modern designs. With its proprietary 10-amp transformer and flexible attenuation options, the Backline brings that current down to an optimal level for significantly improved performance. The rackmountable Backline accommodates two tube amplifiers, making it ideal for musicians who run a pair of heads in a live-in rack case. It's also great for bass players who need lots of overhead for their power-consuming rigs.
Another benefit of running your amp at optimal voltage is that your tubes will usually last much longer — something many of us here at Sweetwater who've paid a pretty penny for new-old-stock tubes can appreciate. The Backline is far safer and more effective than any standard variac, because it limits the input voltage and attenuates the output voltage. Figuring out your amp's optimal voltage is as easy as Googling the specs, and the Backline's onboard output voltmeter lets you see exactly what you're pulling. The Backline's four voltage-reduction modes let you get as close to optimal as possible, and there's a bypass setting so you can A/B the results.
