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. Because the buffer circuit is placed immediately after the input, it can be made compact without the need for a separate buffer. It is designed for continuous use, so there is no ON/OFF switch. 【Specifications】 ・Case: 39 x 92 x 31mm ・Power: Center negative 9V ・fPtoP wiring using universal board ・Junction Box: 2 Loops 【Customer Reviews】 "I think it's great that you can build something like this. It works well. ^_^" "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 the sound became full of vibrancy and charm! It's truly wonderful! Thank you very much!!" As expected of a legendary device. You can see why professionals all use the Kentaursu buffer. I tried 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 more, making it very pleasant to play. Overall, it gives the impression that the sound has more punch and energy. You will likely feel the effect more as you play louder or use more effectors. A buffer is not a piece of equipment that provides a dramatic change like a distortion effector, but it is recommended for those who use multiple effectors, those who are concerned about sound degradation or noise, those who use long cables, and those who want to improve effector response. It is basically intended to be connected directly after the guitar or bass and used constantly ON. *This is a piece of equipment where the effect is difficult to perceive audibly, so we recommend purchase only for those who have knowledge of buffers. Since it is handmade, there may be minor scratches that occurred during production. Please refrain from purchasing if you are concerned about this.
