The GR Dual is a head created for the modern and demanding bass player with a flexibility never seen before on a bass amplifier. The Dual features two separate channels, one of which is completed by a professional overdrive for slight saturations or massive distortions. Each channel is provided with a 4 band eq with 6 selectable frequencies on the mids, deep and bright filters. The Dual offers the possibility to connect two instruments (two bass or one bass and one keyboard) but also one instrument with the possibility of using the two equalizations alternatively or simultaneously.
