Built with a gold-plated-contact phase inverter, LTHZ transformer, and the option of stereo input, the Lehle Little Dual Amp Switcher is a reliable, compact choice for toggling through your rig. Conceived as the little brother to the Lehle Dual SGoS, this smaller rendition's A and B options operate with zero loss and hum no matter the amp, guitar, bass, or keys being used. Highly durable thanks to its steel chassis construction, the Little Dual is the perfect option for quick transfer with no fuss.
