The AKG WMS40 Mini Instrument set is the simplest way to go wireless for guitarists, bassists and other instrumentalists. Working off channel 70 (meaning you don’t need a license in the UK), this ISM1 system operates at 863.100 MHz. You can use up to 3 WMS 40 systems simultaneously – just make sure you mix and match ISM 1, 2 and 3 units so the units do not interfere with each other. This wireless guitar system from AKG gives you the freedom of the stage without the prohibitive price often associated with wireless music gear.
