The British Sound from JOYO gives you masses of versatility in one pedal. You can go from early 60's Marshall tone right up to the higher gain of the JCM800 & 900 series and everything in between. With the gain knob and voice knob hovering around the 9 'o' clock point you can happily conjure Claptonesque tones from your guitar, winding them both up to about 12 'o' clock will get you a 'Woodstock' sound reminiscent of a certain Mr Hendrix. As you go on from there you'll get more and more drive as you turn up the gain knob and voice knob to taste. Led Zeppelin, Gary Moore, Slash, Pete Townshend, Zakk Wylde, Yngwie Malmsteen & many more artists chose to use Marshall and you can replicate their tones thanks to the British sound.
