The #1 Pro Choice is BrownBox

Why Voltage Optimization?

Voltage Optimization  provides numerous benefits: 
  1. Earlier tube saturation equals   earlier break-up at lower usable volume levels .
  2. A smoother tonal shift  toward even order harmonics, revealing  the amplifier's designed tone fundamental , the basis of  your signal chain and the starting point in building a consistent signature tone.
  3. Lower internal voltages = lower dissipation = longer component life.

BrownBox Key Features

BrownBox was created to provide a safe range of voltage reduction levels for vintage tube amplifier designs. The same, era-correct voltage levels that the amps were designed around.

The dynamics of a vintage amp supplied with the proper line voltage are optimized and will sound and respond as originally intended, revealing the circuits true harmonic content. This is the starting point, the basis of the signal chain, and where serious musicians begin creating a signature tone.  

Most vintage tube amps respond more harmonically and touch sensitive with optimized voltage . Placing these circuits  back into  balance reveals the authentic tone fundamental of the amp, tone that can truly blossom. 

For the Tube Tone Purist, no pedal or attenuator can come close to replicating the heavenly response of dry, purely saturated tubes. Pedals and attenuators have their place, keeping in mind that they color your tone, not create it.

Everyone can enjoy multi-dimensional, pure tube tone, if they just know where to start. 

BrownBox is not a variac. Unlike a variac, Brownbox cannot accidentally harm or destroy your amplifier. The maximum input voltage available using BrownBox is your regional line wall voltage, in bypass mode. All other selections are reduction levels that you determine sound best for your amp.
