The ultimatePLUG combines the functions of the silentPLUG and timbrePLUG into a single product: Silent Switch: The ultimatePLUG automatically mutes the instrument cable (short-circuits it) to prevent crackling and popping noises when switching guitars while the instrument is powered on.According to the manufacturer, the integrated REED-based silent switch is rated for more than 10,000 plug cycles. Sound Options: With the ultimatePLUG, you can easily adjust the tone in four steps by turning a knob on the plug. This opens up a wide range of new sounds. The neutral, clear sound takes on a warm tone. https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2017-08-06 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2018-04-24 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2018-06-28 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2018-12-17 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2019-01-02 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2019-04-02 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2021-05-04 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2022-04-27 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2022-10-13 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2023-10-27 https://elecena.pl/product/9719941/np2rx-ultimate-2-pole-1-4-zoll-guitar-plug-ultimateplug 2026-10-14
