Un article intéressant pour les utilisateurs de cette pédale, sur sa transparence ici : https://www.jhspedals.com/tech-articles/ =>Partie Volume Pedal Woes (Active/No Loss Mod)
Citation de jhspedals.com :
To understand why your EB Volume pedal is hurting your tone, let’s look at how it is designed and the issue at hand. You would think that after you plug up your new EB VP that your guitar goes into the Input and then out of the Output to your amp…right? Wrong!!! The Input of the volume pedal is tied in parallel to the “Tuner Output.” What does this mean you ask? It means that your guitar’s signal is not directly hitting the output, but rather it is hitting the tuner out as well.
This is a called a passive parallel split and it is killing your tone in a couple of ways. As you may have learned already from our “Buffer” article, your guitar’s output is a high impedance signal (high resistance/low signal strength). In simple terms, your guitar is a weak signal and when it hits guitar cables, pedals, more cables, and then another long cable to your amp…you’re going to need a buffer. In the case of this volume pedal, your weak guitar signal is getting split in half!!! Basically the parallel split is splitting your signal and weakening what was already in need of buffering. Everything mentioned above is assuming you have not placed a tuner in the “Tuner Out.” If you have hooked up the “Tuner Out,” then the situation actually gets worse. The input of the tuner attached to the tuner out will cause more loss due to the impedance drag on your signal path. This also causes transient noise between your tuner and signal path that shows up as background noise, pops, digital tones and other strange things you don’t want in your rig.
Pour ceux qui ne lise pas l'anglais, l'auteur dénonce le câblage en parallèle à l'intérieur de la pédale avec la prise tuner ce qui a pour effet d'affaiblir le signal de la guitare. Et brancher un accordeur empirerai les choses...
