Lehle RMI Acouswitch IQ Acoustic Preamp DI Pedal


The Lehle RMI Acouswitch IQ is a preamp pedal that's meant for professionals who gig with multiple acoustics - so it is understandable for it go under the radar for many.

This three-in-one unit houses an acoustic guitar preamp, 3-band EQ with extra tone shaping controls, guitar switching feature and DI box functionality.

It can serve as your main pedal where your instruments, tuner and effect pedals can connect to for easy access every time you perform, able to handle complex rigs and simplify connectivity and operation.

I'd also point out that this unit takes up quite a lot of space, so pedalboard space availability should be considered when getting this one.
