Launched in NAMM 2010, British string maker Rotosound are to introduce dual guitar string sets branded "Double Decker" after the iconic British double decker bus.

The formula is simple Rotosound have taken two sets from their mot popular Roto nickel on steel "Roto" range and have housed them in a single pack.

The incentive to guitarists is a reduced price when compared to buying two single sets of the same strings.

The first Double Decker sets will be available in stores early 2010 in the most often requested 9 and 10 gauge sets. (Roto Pink 9s and Roto Yellow 10s)
