The Rockville G-AMP 10 guitar amplifier is a 10 watt guitar amplifier with a 6 inch speaker. This compact size amp is extremely portable and light. It plays really loud and clear for its size!. . We added Bluetooth so you can play your favorite tracks and jam along.. . There is a clean and overdrive channel with a gain knob so you can control the intensity of the distortion. Please note our competitors just have an overdrive button without a control knob. That is a big difference. It really will not sound proper without the adjustment knob.. . We also have the standard bass and treble adjustments so you can fine-tune your sound.. . Our amp sounds excellent.. .
