We have received a shipment of the Micro Mixer KM-04,

a rare analog mixer that symbolizes BOSS’s golden age.

Despite its compact chassis, it features 4 input channels,

making it a practical model that allows you to neatly organize

multiple pieces of equipment.

Each channel is equipped with an independent volume control,

allowing for precise level adjustments, so it performs well

when combined with various instruments such as guitars,

basses, and keyboards.

BOSS’s signature simple yet robust design

is still highly regarded today and enjoys enduring popularity

among fans and collectors of classic Japanese-made

effects.

This is a model rarely seen these days,

and it fully captures the unique atmosphere of BOSS products from that era.

The unit shows some signs of use, but overall

it remains in good condition.

Basic functionality has been verified. There is some scratchy noise when turning the knobs

, but otherwise, it is in working order

and ready for use.

In recent years, the popularity of vintage BOSS products

has been rising both domestically and internationally, and the number available on the market is on the decline

, so if you’ve been looking for one, please don’t miss this opportunity

and consider purchasing it.

This listing is for the unit only.

The Tech 21

SansAmp Classic, a classic model that remains highly popular to this day, has arrived. Known as a pioneer in amp simulators,

this masterpiece continues to enjoy strong support

from players and recording engineers

around the world.

Equipped with an 8-position Character switch,

it allows for a wide range of sound shaping

from clean tones to driven sounds. It features

a warm, tube-like texture and natural response,

making it versatile across various genres.

In addition to switching between Lead, Normal, and Bass input modes

, controls such as Presence Drive and Amp Drive

allow for precise tone shaping. We believe

this is a unit that lets you enjoy a unique character

that is hard to find in modern equipment.

It remains a model with enduring popularity both domestically and internationally

, and we believe you will find it highly appealing

not only as a collector’s item but also as a practical piece of gear

. With few units currently on the market, this is a unit we can

highly recommend to anyone who has been searching for one.

There are no noticeable scratches or stains on the unit, and it is in good overall

condition; however, there is some crackling when adjusting the knobs

and occasional noise when adjusting the OUTPUT,

so we are listing it as-is.

We hope you will consider this item.
