Keeley Time Machine Boost

This is a 2 channel, 3 mode pre-amplifier (booster) for driving your amplifiers into overdrive or saturation. The two channels on the pre-amplifier are labeled Vintage and Modern. The Vintage side is inspired by rare germanium boosts like the Dallas Rangemaster. The Modern side a new +23dB gain dual JFET, very transparent, guitar signal amplifier and 18 volts.

The Time Machine Boast design uses a Maxim MAX1044 voltage doubling IC to get additional headroom. As with all Keeley pedalsit incorporates top of the line audiophile style parts including metal film caps, resistors, and silver solder! Teflon-coated wiring leaves this unit breath-taking on the inside.

The pedal has a wide range of uses. Use the Time Machine Boost to further overdrive your tube amplifier into more harmonically rich distortion or as a preamp to strengthen the output signal of your guitar's pickups. Its two footswitchable channels with independent volume levels provide further dynamics, tone shaping, and versatility.

The Modern channel is specially voiced to transparently squeeze additional natural gain from your tube amplifier to pump up your rhythms or solos. It is a completely independent circuit and design from the Vintage channel. The Modern channel maintains the natural tone you already have, but just gives you"more" of it by strengthening the signal from the front end with no tonal coloration and full transparency! If your amplifier is already being overdriven, the Modern channel can take your amp's overdrive "over the top" for beautifully compressed, sustaining leads. The modern channel also can function as preamp and can blend its boosted clean signal to an perfect for musical passages that need to stand out.

Warp Drive: When using the Modern channel, engaging the Warp Drive switch adds additional drive gain and harmonics. The transparency and full fidelity and frequency response of the Modern channel remains true while in Warp Drive.

Or click the footswitch to travel back in time with the Vintage channel to alter your sound with boosted tones that sing with musical sweetness and rich harmonics unique to those eras of the past. The circuit is completely independent from the Modern Channel and unique, taking only the best from the past and refining the rest. The Vintage channel brings you two modes to travel to: "1966" and "1973".

Toggle into "1966" and crank your amp up for tones that blend smoothly and put you up front in the mix by adding extra top-end sparkle with a mild overdrive. 1966 brings you back to the booster tones used by many of the British greats of the era and is especially designed to be used with an amplifier that is already being overdriven. Or, toggle into "1973" to fatten up and boost your single coil-equipped guitar, or add extra meat to the tone of your favorite humbucker-equipped guitar without losing definition or turning the sound to mud. "1973" will enable your guitar and amp to deliver a smoother, full-ranged rock n' roll crunch with just the perfect amount of midrange, reminiscent of the best boosted rock tones of the era.
