NUX Stageman Floor ACOUSTIC GUITAR PREAMP WITH LOOPER. Stageman Floor is an analog acoustic guitar preamp with digital effects and a built-in looper. It features a 3-band EQ with a special midrange control, adjustable notch filter, and gain control. The Reverb and Chorus effects are each controllable with a dedicated knob that automatically blends the various parameters optimally for perfect balance. The Chorus can be used in Freeze mode by pressing and releasing the dedicated footswitch. The input can be optimized for piezo/magnetic inputs, while the FX expands its usage options. But there's more: Stageman Floor can also transform into a looper with 60 seconds of memory and infinite overdubs. It's also perfect for instruments such as violin, mandolin, banjo, and many others.
