Tronical, the people who have invented the Powertune automatic tuning system for guitars have been in touch to tell us that the system is now in production and that they will be showing it off at this week’s Musik Messe in Frankfurt with Scorpions guitarist Uli Jon Roth doing the axe-wielding.
If you can’t make it to the show however, they wish to draw your attention to a demo video that’s now online at YouTube. You may also wish to see the vid that we shot at this year's Winter NAMM show in January (see story in Tronical news below).
