This is the Ovaltone / FOUNTAIN HS-model. It is fully functional, in excellent condition, and practically new. I purchased it from an authorized domestic retailer and have kept it in its box indoors after testing it for about 30 minutes. It's from the first production run, and I understand the serial number is in the teens, making it a valuable unit. The following is an excerpt from the product description: Based on the FOUNTAIN 2025 ver., this pedal was co-developed with guitarist Hidehisa Sasaki. It adds another stage of hard clipping to the FOUNTAIN, resulting in a model that has a distortion-like bite and sustain within a smooth overdrive. The internal voltage boost is optimally tuned for standalone use or lead playing, primarily without relying on the amplifier's compression, making it versatile. Power: Stabilized AC adapter or power supply (DC9V, center negative 2.1mm) Size: (W)72 x (D)127 x (H)56 (mm) *including protrusions. Internal construction: The main circuit is hand-soldered, and some SMD components are used in the power supply circuit. I think this is a great deal for those considering a new purchase. Thank you. #HidehisaSasaki #AssH #Ovaltone
