The Tone Garage series – the pure essence of analog effect units

Tone Garage captures the pure essence of analog in these compact effect units by pairing carefully selected components with a unique design philosophy. The philosophy of the Tone Garage series is to perfectly convey every performance nuance with inimitable tonal character without compromising the sound of the guitar. These pedals, which feature carefully selected analog parts such as vacuum tubes and BBD chips, use rigorously refined discrete circuits. VOX’s unique new Hi-Volt technology allows the internal tube to operate at 200 volts, even when using battery power.

Main Features

• FLAT 4 BOOST feature a full range booster that delivers true vacuum tube sound
• All-discrete circuitry - the result of a relentless design philosophy
• True bypass design provides tonal confidence even when the effect is off
• Tough die-cast body that stands up to the rigors of the road
• Newly developed Hi-Volt technology allows the tube to operate at 200V, even on battery power
• Gain control lets you adjust the tonal character
• Heater current’s slow start circuit ensures vacuum tube longevity

A versatile full-
range booster

The FLAT 4 BOOST takes advantage of VOX’s newly developed Hi-Volt technology and provide not only the warm tone expected from a tube but also the all important feel and dynamics.

This vacuum tube booster can be used for a mid-boost, treble-boost, and overdrive, in addition to a full-range boost. Its Baxandall tone circuit allows adjustment from the flat position to the desired boost or cut range.

Raising the gain will gradually apply a low-cut, giving you an overdrive sound that's strongly reminiscent of sought after vintage tones.

An independent mid-boost switch lets you switch the response of the mid-range, which is ideal for playing lead. This is a great unit for blues guitarists who wish to highlight their picking nuances.

Relentlessly honed all discrete circuitry

The internal structure of the Tone Garage series contains absolutely no integrated circuits such as op-amp ICs; it consists only of individual parts such as transistors, resistors, capacitors, and coils. In other words, this series uses unmistakably all-discrete circuitry. Guided by a relentlessly honed design philosophy, only carefully selected parts are used. These pedals provide an excellent response to the subtle picking nuances of the discerning guitarist.

Sturdy aluminum die-cast body for outstanding durability

Each pedal in the Tone Garage series features a tough aluminum die-cast body for outstanding durability. It will stand up to hard knocks during your stage performances. Simply seeing the killer graphics is enough to rev your motor and take your performance up a notch. The power supply, vacuum tube, and other internal circuitry are partially visible, projecting VOX's traditional design sensibility via appearance as well as sound.

Newly-developed Hi-Volt technology

VOX has revealed new vacuum tube circuit technology. This new technology is called “Hi-Volt”. This delivers high voltage to a 12AX7 vacuum tube, by using 6x AA batteries or the DC9V power supply. “Hi-Volt” delivers 200V to a 12AX7 tube stage.

Hi-Volt technology enables the vacuum tube to operate at 200V while still running on a battery. This enables a true drive sound that overturns your expectations for a compact effect unit.

The discrete circuit works at 20V, which is still considered high voltage operation compared to other general effects products. The result is a natural and dynamic tone which is similar to that of a vacuum tube amplifier. Even though vacuum tubes are considered big by modern component size standards, our engineers were able to keep these pedals small, so you don’t have to worry about them taking up too much space on your pedal board.

Gain control that lets you vary the character of your sound

The transistor amplification circuit has also received a good deal of consideration. We've designed the gain control so that adjusting its position does not simply change the amplitude, but will also change the tonal character in a subtle way. We feel that any position will yield usable sounds.

Carefully designed power supply circuit that extends vacuum tube lifespan

Since high current flows through a vacuum tube when the power is turned on, we have provided a heater current slow start circuit that extends the lifespan of the vacuum tube and also avoids malfunctions for the AC adapter.
