This is a speaker emulator from UAD. After checking its functionality, I ended up hardly using it. I will also include the separately sold dedicated adapter. Although it has almost no signs of use, please consider this item as a used product. The explanation will be lengthy, so I will attach the URLs. < OX STOMP> https://www.soundhouse.co.jp/products/detail/item/337109/?srsltid=AfmBOoql2aZQBktik6kuimu-WM1KiqDVmfDb1NeYXeINN87Kv-OZ8Bld <PSU-GP1-WW> https://www.soundhouse.co.jp/products/detail/item/292526/?srsltid=AfmBOopid1UhfYIzOc2oRbuo9JbhgJUROcfwcT1wpnOEeG1zyBHjxV3G
