Thank you for looking. This is a junction box from [Lagoon Sound]. It is equipped with a tuner out and volume function. The volume can be used as a master volume. The enclosure is a high-quality custom-made item from Hata Precision Industries. They designed it to be highly resistant to noise and measured it to be the perfect size for the volume pot. The manufacturing cost was around 40,000 yen. It was attached to my effects board once, but has never been used. The velcro for attachment will be included as is. It can be peeled off cleanly, so please remove it if you do not need it. I am also selling many other effect pedals, so please take a look if you are interested. Type: Electric Guitar
