ce serait sympa une video sur le hard et soft clipping.
La différence de son entre les diodes germanium 0,3V, led (1,2V) et silicium 0,6V...
La pédale vht vdrive est très intéressante car elle permet de choisir entre tout ça combiné à un ampli op et des configurations symétriques et asymétriques
“Position 1 has a 1N34A germanium diode, and it has two diodes on one half of the waveform and one diode on the other half. Some versions of the Fullxxx Fullxxxxx use a germanium diode and asymmetrical clipping.
Position 2 uses two 1N4148 for symmetrical clipping, the famous Ibaxxx Tube-xxxxxxx pedals (and the multitude of similar boutique clones and variants) use this diode combination.
Position 3 has three 1N916A diodes and a 2:1 clipping ratio for asymmetrical clipping, same as the Boxx SD-x (there are numerous clones and variants of this pedal too, but surely not as many as the Tube-xxxxxxxx).
Position 4 is an unusual diode combination unique to the V-Drive
Position 5 has two infrared diodes for symmetrical clipping, this is unique to the V-Drive
, we know of no other company using infrared diodes. This is our contribution to the advancement of the art.
Position 6 is a very unusual combinations of diodes that are found in a popular super-smooth sounding overdrive pedal with a name borrowed form eastern religion: xxx-Drive.
Position 7 combines half of Position 6 with an infrared diode, producing a unique dynamic response, smooth with some bite.
Position 8 also uses the more unique half of position 6, but with a red LED for more asymmetrical clipping.
Position 9 uses a pair of matched red LEDs for crunchy clipping, reminiscent of some things from a popular british amp maker.
Position 10 tilts the two red LED combination towards more asymmetry by adding a silicone diode to one side.
Position 11 has no diodes, for a clean boost, with some op amp clipping at higher drive settings.
Lastly is the voltage control. The VHT V drive
features a voltage amplifier that allows the voltage to set it from as low as 5v up to 18v! At lower volts it has a splattier more compliant tone and increasing it allows for more articulation/ headroom/ authority.
