Please refrain from price negotiations. This is a guitar kill switch, a best-selling product from "BADPEDAL," a handmade effects pedal and custom paint brand from Okayama, Japan. A kill switch is a device that mutes the instrument's sound only while the button is pressed. It allows for playing styles like those of John 5, Buckethead, and Berried Alive. As a side note, the kill switch techniques used by Tom Morello (RAGE AGAINST THE MACHINE) require sound only while the button is pressed, so this unit is not suitable. In that case, please consider the model with a reverse switch, which is also listed. High-Quality Sound Design: * True bypass * Audio signal lines use BELDEN 8503 cable * Passive circuit design that does not add unnecessary electrical coloration * High-quality, made-in-Japan electronic components selected after comparative testing Wide Range of Applications: * Can be used as a momentary footswitch with an A contact (normally open) type for expanding effects pedals, such as tap tempo (some exceptions apply, but BOSS products generally cannot be used. Please refer to the images for details) Excellent Operability: * Uses Sanwa Denshi push-button switches, used in arcade game machines * Offers superior operability and durability compared to standard footswitches, whether used with fingers or feet Shipping: * Free shipping nationwide * Shipped via Yu-Packet Plus (anonymous delivery with tracking) * Delivered to your mailbox in a dedicated box (hand-delivered if it doesn't fit)
