Lehle P-Split Splitter Guitar Pedal

P-Split stands for "passive splitting" with maximum signal fidelity. With the Lehle guitar pedal, one instrument can be routed to two amplifiers simultaneously. Output A is electrically isolated from Output B by the Lehle LTHZ high end transformer — so ground loops are excluded from the start. In addition, the Lehle P-Split also features a gold-plated-contact phase-reversing and ground switch.

Lehle LTHZ

The Lehle LTHZ is a ferrite core transformer consisting of two coils with very high inductivity with minimal scatter. It is ideal for the galvanic isolation of high-impedance signals.


1 The input signal should be fed into this jack. The Lehle P-Split operates purely passively. The input signal remains continuously connected to outputs A and B with no semiconductors or any other active component in the signal path.

2 The input signal and its ground are directly present on jack B.

3 This switch can be used to rotate the phase of the input signal on output A through 180°. Shifting the phase may help if phase cancellations have a negative effect on signal reproduction.
4 Pressing this switch connects the grounds of outputs A and B.

5 The input signal is present on jack A, electrically isolated by the Lehle LTHZ (7) high-end transformer.6 The base of the Lehle P-Split can be secured without difficulty. First remove the four housing screws for the cover, and then screw the base of the switch to a base-plate using the two screws supplied with the unit, the washers and the spacer elements.
