This compact junction box houses the buffer section of the Kentaursu, which is reputed to improve and thicken the sound simply by passing your signal through it. It consolidates all board inputs and outputs in one place, helping to prevent jack damage from repeated plugging and unplugging. Since the buffer circuit is placed immediately after the input, it allows for a compact design without the need for a separate buffer. It is designed for continuous use, so there is no ON/OFF switch. 【Specifications】 ・Case: 50 x 50 x 30mm ・Power: Center negative 9V ・PtoP wiring using universal board 【Customer Reviews】 "I think it's great that you can build something like this. Works great. ^_^" "I'm a repeat customer because it does such a great job." "The sound quality has improved and is wonderful." "It's confirmed to be on my main board. Thank you." "The sound became surprisingly good!! The sound image became clear, and it transformed into a sound with a punch and a touch of sensuality! It's truly wonderful! Thank you very much!!" It's a masterpiece, as expected. You can see why professionals all use the Kentaursu buffer. I tested it by placing it before my Vemuram Jan Ray, and the sound became thicker, the cutting became crisper, and the dynamics of the clean sound, with a moderate amount of distortion, increased even further, making it very pleasant to play. Overall, it gives the impression that the sound has more punch and energy. You'll likely feel the effect more as you play at higher volumes or use more effects. A buffer isn't a piece of equipment that provides a dramatic change like a distortion effect, but it's recommended for those who use multiple effects pedals, are concerned about sound degradation or noise, have long cable runs, or want to improve the interaction between their effects. It is basically intended to be connected immediately after the guitar or bass and used constantly ON. ※This equipment's effects may be difficult to perceive audibly, so we recommend purchase only for those who have knowledge about buffers. As it is handmade, there may be minor scratches or imperfections that occur during production. Please refrain from purchasing if you are overly concerned about such details. Kentaursu Klon Buffer
