Guitar World Verdict

This pedal is designed for a specialised job, and it does that job perfectly. While it’s handy if you need a substitute for a keyboard player, there are plenty of new textures on offer when you mix the strings proportionately with guitar.

With its ‘9 Series’, Electro-Harmonix has created a minor genre in pedals that recreate the sounds of other (mainly keyboard) instruments from any electric guitar – no additional synth pickups required. 

The latest, String9, has been designed to emulate orchestral and synthesiser string sounds and, to that end, offers the well-established array of nine different sounds selected by a rotary knob.
