Presenting the AmpRx Brownie Gig Master Voltage Regulator for Guitar Amplifiers.
Like its bigger sibling the BrownBox, The AmpRx Brownie Gig Master 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 circuit's 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.
The Brownie is the answer for the budget minded player, or just the Small amp owner. The Brownie tube amp power correction unit enjoys a huge fan base. From bedroom players to lifelong touring Pros, the Brownie is for those who only need Basic Voltage control in a super light weight enclosure. The Brownie will provide 2 amperes or 240 watts of continuous power @ 120vac. designed for smaller Tube amps (Deluxe Reverb, Champs , Princeton, etc,) and Pedal-boards. It offers 8 on the fly selectable voltage levels. The Hi/Lo switch provides and instant 5 volt + or - re-scale from the current selected voltage level, an excellent feature!
Why do you need Voltage Optimization for your amp? Voltage Optimization provides numerous benefits:
Establishes the basis for your signal chain and the starting point in building a consistent signature tone. Earlier power tube saturation equals earlier break-up at more usable volume levels .
A smoother tonal shift toward even order harmonics, revealing the amplifier's true designed tone fundamental .
Lower internal voltages = lower dissipation = longer component life.
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.
The AmpRx Brownie is NOT a variac. Unlike a variac, Brownie cannot accidentally harm or destroy your amplifier. The maximum input voltage available using Brownie is your regional line wall voltage, in bypass mode. All other selections are reduction levels that you determine sound best for your amp.
The BrownBox and Brownie employ a proprietary, American made, 5 amp transformer, intended for use with one amplifier. AmpRx's proprietary transformer was custom wound exclusively for use with tube amplifiers - no off the shelf transformers or test-bench variac's here!
The BrownBox was created by a team of experienced player/ technicians with the professional player in mind. That meant first it must be intuitive and easy to use every time. Secondly, it must also have a road rugged design and be able to take abuse. Thirdly, it must be practical and superior to any other voltage reduction option. The BrownBox is completely proprietary in design and function and comes with a lifetime warranty with normal use.
Caution: BrownBox and related Products are A/C Electrical devices designed for professional use. Use by non-professionals or minors should be fully supervised. Serious injury or Death can result from tampering with or opening the chassis." For Use in DRY locations only". User assumes all liability. Opening of the Chassis voids the warranty.
