Fryette Valvulator Mini Tube Buffer

The Fryette Valvulator Mini is a high voltage, vacuum tube–based buffer that is perfect for guitarists who utilize modelers, digital amps and long pedal chains. Designed to preserve and enhance your guitar’s tone by converting the signal from high to low impedance eliminating high-frequency loss and signal degradation caused by cable capacitance, impedance mismatches, phase/ground loops and the use of effects pedals. The tube buffer also acts as a tone sweetener, cleaning up and enriching your sound while unveiling subtle harmonics, dynamics and the touch sensitivity normally associated with plugging directly into an amp.

PRESERVE YOUR GUITAR'S TONE

Housed in a compact steel chassis, the Valvulator Mini provides an unbalanced low-impedance output, an unbalanced transformer isolated output and a balanced XLR output, making it a versatile solution as a tube direct box for both pedalboards and studio use. It used a JJ 12AX7/ECC83 vacuum tube and is powered by 120-volt AC and includes an AC adapter. Two impedance switches eliminate high-frequency loss and signal degradation caused by cable capacitance and the use of effects pedals. The phase switch keeps you in phase, ensure full tone. The ground loop switch assists in eliminating hum. It features a 1/4" input along with unbalanced low-impedance 1/4", unbalanced transformer isolated 1/4", and balanced XLR outputs.

THE VALULATOR EVOLVED

The Valvulator Mini is the long-awaited evolution of one of Fryette's most popular rig solutions, the Valvulator 1 Vacuum Tube Buffer. The Mini features increased headroom and dynamic range, together with significantly lower noise. "As always, I wanted a solution for myself that I knew would be a welcome tool for players, especially those who really appreciate the tone and feel of plugging directly into an amp," commented Steve Fryette.
