Rare Item: Seamoon Funk Machine SPI Mod

This Seamoon Funk Machine has been modified by the renowned effector workshop Soul Power Instruments.
Internal parts have been upgraded, and the internal slide switch for setting the input PAD and the trim pot for adjusting amplifier gain have been relocated to the exterior. This allows for easy adjustments without needing to open the back cover.

[From the manufacturer's description]
In the 1970s, a large filter pedal was found at the feet of funk bassists worldwide.
That was the Seamoon Funk Machine.

The Funk Machine, which creates the essential tone of funk bass, is revived by the ears of world-class bassists and the hands of world-class builders. That is the Seamoon FX Seamoon Funk Machine.
It covers the tone of the original model and goes beyond it. The goal was not simply to reissue it, but to make it the most user-friendly for today's players. This proved to be far more challenging than imagined. It had to be an analog circuit, just like the original, and a pedal with the overwhelming response unique to the Seamoon Funk Machine.
And it has been achieved, and now, the Seamoon Funk Machine descends anew.
