Maintained by the manufacturer! Genuine Oba Shoji product. JEFF ROWLAND's highest peak preamp. The hard aluminum hollow-out chassis is condensed into a compact size with a width of less than 400 mm. You can enjoy the feeling that chunks of sound with a dense texture are comfortably colliding with each other. In particular, the detail, gentleness, and sound of the nuances when running on a battery are exquisite. Use battery mode for vocals, and AC mode for jazz, rock, etc. The exterior is slightly dull and has a feeling of use. *To prevent microcomputer malfunction due to static electricity, connect the main unit to the power supply unit with an attached ground wire. Please see the USB terminal on the back (Ryo Mizusaki)
