I like to use the <br />3PDT Wiring Board from GuitarPCB for the bypass switch and like to use a red/green Led showing Bypass status and another red/green or better green/yellow Led for Output Jack and Buffer Out status.

pour tout ceux qui ont un problème...Bonjour à tous,<br />pour tout ceux qui ont un problème avec la fréquence et l'oscilation le problème le suivant ! Lalaland à raison au sujet du buffer c'est dailleur pour ça que je ne me suis pas rendu compte du réel problème car sur mon pédalboard la vh4 est situé après une pédale (Zoom) qui a un buffer intégré ! <br />SI VOUS NE SOUHAITEZ PAS UTILISER LA PEDAL AVEC UN BUFFER, il faut en fait redessiner le pcb en déplaçant le potentiomètre des aigus le plus loin possible de l'entrée du PCB ! C'est ça le probème !<br />J'ai redéssiner le PCB en faisant ceci et tout fonctionne parfaitement !<br />Bien sûr je veux bien partager mon shéma, mais sachez que j'ai inclu le footswitch dessus et que le shéma est fait en vectoriel pour une gravure à l'anglaise … Bien sûr les câbles blindés sont toujours d'actualité sur les 2 output, le input, le pot gain et pot volume …<br />Si vous faites tout ça ça marchera … C'est garanti !!!<br /><br />Si David est ok avec le principe, vous pouvez également m'acheter le pcb gravé à l'anglaise et étammé à froid ! (pour les français uniquement)<br />Cliquez sur le dernier lien de "DIY links"<br /><br />David, si tu lit ce message dit moi comment t'envoyer le document …<br /><br />Sur ce, bon montage, et "Rock on !!!"<br /><br />Hello everyone,<br />for all those who have a problem with frequency and oscillation the problem following it! Lalaland reason about the buffer it's spoiler for that I did not realize the real problem because on my pedalboard the vh4 is located after a pedal (Zoom) that has a built-in buffer!<br />IF YOU DO NOT WISH TO USE THE PEDAL WITH A BUFFER, you must actually redraw the pcb by moving the treble potentiometer as far as possible from the PCB input! That's the problem!<br />I redesign the PCB by doing this and everything works perfectly!<br />Of course I want to share my schema, but know that I included the footswitch on it and that the diagram is done in vector for an English engraving ... Of course the shielded cables are still relevant on the 2 output, the input, the pot gain and pot volume ...<br />If you do all that it will work ... Guaranteed!<br /><br />If David is ok with the principle, you can also buy me the cold-etched English-language pcb! (for French only)<br />See the last link in "DIY links" session<br /><br />David, if you read this message tell me how to send you the document ...<br /><br />On this, good editing, and "Rock on !!!"Franckhttps://www.blogger.com/profile/04119138753276877255noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-51144288559143841622019-09-11T14:57:55.077-04:002019-09-11T14:57:55.077-04:00output pcb to the switch et the output jack to the...output pcb to the switch et the output jack to the jack output !

An unwanted frequency and an oscillation when you exceed twelve o'clock on the gain knob! Indeed this pedal has a very high gain circuit and therefore it radiates a maximum! To remedy the problem it is imperative to wire the gain potentiometer and the volume potentiometer with a shielded cable, but also the input jack, the output jack, the buffer and the power Amp !!! with this, no more noise! If you want more detail about the type of cable I used contact me ... :)<br /><br />In French :<br />salut à tous, j'imagine que comme moi tout ceux qui ont fabriqué cette pédale ont été confronter à un probleme ! Une fréquence indésirable et une oscillation lorsque que vous dépasser midi sur le potentiomètre de gain ! En effet cette pédale à un circuit gain très élevé et de ce fait ça rayonne un maximum ! Pour remédier au problème il est impératif de câbler le potentiomètre de gain et le potentiomètre de volume avec un câble blindé, mais aussi le input jack, le output jack, le buffer et le power Amp !!! avec ceci, plus aucun bruit !
