Little Lehle II The Little Lehle II is a genuine True Bypass looper/switcher. It can be used to manage an effects loop, or as a simple A/B box. Two instruments can be optionally routed to one amplifier input, or one instrument switched back and forth between two amplifiers. The gold-plated switcher contained in the unit switches with maximum signal fedelity. The seperate switching level for ground contacts makes ground loops impossible. Little Lehle II offer full stereo functionality with all jacks and internal switching contacts executed in stereo.
