This is a high-end compressor pedal from Source Audio. Manufacturer's suggested retail price: ¥39,600 *I used this as my main compressor for bass for about a year, but I'm reluctantly selling it because I need funds.* It allows for a wide range of compressor settings using dedicated software, can save up to 6 presets, and can also be used like a preamp because you can set EQ and other parameters. You can also change the settings with a smartphone app, making it easy to adjust settings in the studio, etc. I think it has a very natural, original-sound-focused, and wonderful sound. You can also create aggressive sounds with multi-band compression and EQ. This one pedal can do a lot, so I think it would be a great asset, especially for players who have experience with mixing and understand the basics of compressors. Even if you don't, you can still get a great sound just using the presets + knobs, so it's a compressor that I can recommend to many people. Box, accessories (genuine USB Type B-A cable, genuine AC adapter, genuine shielded cable), warranty card, etc. are all included.
