barbarossa Posted September 28, 2014 Posted September 28, 2014 (edited) vreau sa schimb toggle switch-ul de la sustainiac pt on/off cu un potentiometru push/pull cei de la sustainiac imi spun ca trebuie sa iau un potentiometru push/pull asa: "For ON/OFF the switch must be "break-before-make" type, not "make-before-break". Otherwiseyou will get loud pops when the neck pickup is selected and you turn theSustainiac ON or OFF" la sistemul sustainiac, cand selectorul de doze e pe neck (dar sustainiac-ul nu e activat) si se activeaza sustainiacul, se trece automat pe doza din bridge. daca se poate, cineva avizat sa imi indice si mie de pe astea doua site-uri un astfel de potentiometru, calitativ: http://www.banzaimusic.com/Potentiometers/ http://www.thomann.de/de/potentiometer.html multumesc anticipat si apreciez deranjul You can use most any DPDT (double-pole, double-throw, these have six contacts) switch for ON/OFF, as long as the ON/OFF switch is a NON-SHORTING switch (also called "BREAK-BEFORE-MAKE"). You can even use a slide switch if you want, as long as it is NON-SHORTING. In other words, with a SHORTING switch, the middle terminal of a SHORTING switch momentarily connects to BOTH outside contacts AT THE SAME TIME in the middle of the switching actuation. We don't want this because the driver is momentarily connected to BOTH the neck pickup preamp and the sustainer amplifier output at the same time. If the neck pickup is selected, you get loud pops as you turn the sustainer on and off. With a NON-SHORTING switch, the middle contact of each section (pole) DISCONNECTS from both outer contacts momentarily during the switching actuation. This eliminates the pop problem.

FiveseveN Posted September 30, 2014 Posted September 30, 2014 Break-before-make e tipul "normal" de comutator, celălalt e mai greu de găsit și nu l-am văzut în pot-uri push-pull. Sustainiac au insistat să menționeze acest detaliu ca să evite orice problemă, dar nu trebuie să rămâi cu ideea că trebuie un comutator special. 1
