The Traynor YGL1 15 watt all tube 1x12 combo is the ideal 'tone monster' combo for stage and studio. Simple Gain, Bass, Mid, Treble and Master controls make it easy to dial in that perfect tube sound. The three-stage mode switch makes the YGL1 one of the most versatile small combos in this class. The mode switch relocates the tone stack relative to the gain stage, giving the YGL1 either a crisp 'American' style tube amp tone for clarity and definition USA mode or a grittier, more 'spongy' 'British' flavor associated with the great UK amps of the 60s and 70s Brit mode. The third option is a Pure mode which bypasses the tone stack entirely, delivering a mid and overall gain boost allowing for the most direct signal path possible between your fingers and the speaker.
