This item is being listed as "Sold As-Is" (with a noted defect) because no audio is output from Output Channel 4. Channels 1 through 3 have been confirmed to operate normally.

【Operational Status】

・Inputs 1–4 and audio outputs from Channels 1–3 have been confirmed to work correctly.

・No audio is output from Output Channel 4.

・System functions—such as effect selection, parameter adjustments, and the LCD display—operate normally.

・Please note that there is very slight crackling (noise) when operating certain knobs or encoders.

【Physical and Internal Condition】

・Upon opening the top cover to inspect the interior, no burn marks were found on the circuit board; however, a 20-pin IC chip shows signs of partial lifting (the solder appears to be in contact with the board, but the exact cause is unknown as this is a non-professional assessment).

・The rubber feet on the bottom of the unit have partially melted and are sticky.

・Overall, the unit shows signs of use consistent with its age (scuffs and minor scratches), but there is no major damage, and it remains in a condition suitable for practical use.
