Mooer Micro Preamp Series 008 (Mesa Boogie MARK III type). Used indoors after purchase (hardly used). I am selling it to organize my equipment. Thank you. From the manufacturer's website: The Micro Preamp series pedals can be used not only as effects pedals, but also connected to the effects return or power amp input to directly drive the power amp of an amplifier. Furthermore, line recording is possible using a speaker simulator. It can also be output directly to a PA or monitor. - Model name: MICRO PREAMP 008 - Brand: MOOER - Functions: Tone adjustment (TRE, BASS, VOL, GAIN) - CH/CAB: Switch channels by pushing. Also, press and hold for 2 seconds to switch the cabinet simulator ON/OFF. * Please note that this is a used item, so no claims or returns are accepted.
