At NAMM 2007, hall A #6915 and in the Kentia hall E #1276, Tronical unveils the shipping version of the world's first compact automatic self tuning system for electric guitars: Powertune®.

The Tronical Powertune® System tunes electric guitars automatically. Shown as a technological preview at NAMM 2006 already this system is a groundbreaking innovation in the construction of traditional instruments. Now every guitarist can now forget about the danger of a detuned instrument in situations where there's only one chance: Live Concerts and Recordings, TV Gigs, etc.

The guitar that tunes itself automatically now becomes a reality. Perfectly tuned in seconds (re-tune in less than 2 seconds in fact!) at the touch of a button, virtually undetectable, even in front of the audience. All this happens with an accuracy that is beyond manual tuning (typically 0.2 cent). What's more, Tronical's individual memory even takes peculiarities and the musician's personal preferences into account. Pre-programmed or individually saved presets such as open tuning, or special grunge- and slide- settings can be recalled in seconds.

Tronical's Powertune is a modular system that can be retro-fitted to virtually any available guitar make or model, without the need for destructive rebuilding or re-working. The guitar can also be returned to its original state at any time, if needed.

Tronical's Powertune® system consists of three modular main components:

The TuneControl MultiKnob replaces the guitar's volume control. The entire Powertune operating and control functionality is contained within this unique multifunctional pot. In the "Pull" position it acts as a rotary switch for selecting various tunings. Built-in multicolored LEDs offer superb visibility and control over all settings and tunings - even in the darkest or brightest environments! In addition the lens acts as an "Enter" button. The Knob is available in various colors, for fitting the guitar's look.

The Powerhead®-Locking Tuners consist of lightweight micro servo motors and high-performance gears. The servo motor control has an intelligent "learn" capability that allows optimizing any tuning requirements whilst maintaining full manual tuning. Thanks to ultra-light material from aircraft construction the Tuners maintain the physical balance and the guitar's sustain.

The piezo equipped TuneControl Bridge and TuneCore Controller controls and monitors the action of the servo tuners. The TuneCore Controller fits in standard guitar cavities. The TuneControl Bridge comes in two styles: As a Tun-O-Matic bridge (Gibson-style) or as a tremolo bridge (Fender-style). The Fast-Locking mechanisms used in the Powerhead® Locking Tuners guarantee stable tuning even during fierce use of the tremolo. New DSP-based ultra-fast tuning analysis software in the controller electronics calculates the actual tuning - or rather the necessary correction - in fractions of a second. Powertune®'s power supply is a rechargeable battery pack that also fits in the existing cavity of the guitar and charges by simply plugging a guitar cable into the charger. A fully charged battery guarantees several hundred tuning actions before it has to be recharged.

Distributed by Synthax Audio AG Tronical's Powertune System is available in 5 different versions for various guitars in stores in Europe from March. Retail net price in Europe is €610,- excl. VAT. In the US Tronical Powertune will ship for rrp $799,- USD.
