A Modern Classic from Lehle to Secure Your Setups
Lehle has built a solid reputation among demanding guitarists and bassists with routing solutions designed for stage and studio. The P-ISO fits this approach: a simple, robust, and "zero hassle" tool whose mission is to guarantee a clean signal when a setup (two connected devices, two amps, stereo effects, audio interface) generates background noise. Its technological core, the LEHLE TRANSFORMER HZ, aims for uncompromising isolation while remaining perfectly suited for instrument signals.
Who Is the P-ISO For, and When Does It Make a Difference?
The Lehle P-ISO is aimed at any musician who wants a silent and reliable pedalboard, from beginners discovering the joys of interference to professionals playing multiple gigs. It shines especially in live settings (venues with unstable power supplies, multiple devices connected together) and in the studio (reamping, complex chains, patching). If you play in stereo or with two amplifiers, it quickly becomes indispensable: it allows isolating one amp from the other and maintaining a clean sound, even when the entire system tends to hum.

Questions frequently asked
Does the Lehle P-ISO eliminate ground loops between two amplifiers?
The ISO output provides galvanic isolation between two devices to address hum caused by ground loops. This setup is particularly applicable to configurations with two amplifiers or a stereo system.
Does the P-ISO require power on a pedalboard?
Its passive operation requires no electrical power or accessories to function.
Can the P-ISO be used for reamping and studio applications?
It can be integrated into a reamping chain or studio patch where a clean signal is needed. The LEHLE TRANSFORMER HZ is designed for instrument signal isolation. Its use between two devices aims to reduce background noise in complex setups.
What types of signals are compatible with the ISO output?
The ISO output accepts both balanced and unbalanced signals. This compatibility allows routing of an isolated signal to a mixer or between effects.
Does the P-ISO alter the guitar tone?
Designed around the LEHLE TRANSFORMER HZ, this passive device aims for a neutral signal transmission, preserving attack and dynamics. It is suitable for high-impedance instruments, especially in high-gain chains or with stereo effects.
