Sever Potentiometers

Sever Potentiometers
SEVER  !nnovations introduces the Tone Up volume potentiometer with evenly increased volume with the new taper “ P”, to match the ideal physiological hearing perception.
 When choosing a potentiometer, which pot is the best for a guitar.  You need to consider which type/taper to use, what value, open metal housing or sealed closed one, solder or not to solder – this is the question...
To get the best answers it is important to: -
  • Understand how our ears hear.
  • Know what happens when a rotation of potentiometers begins.
  • Know why we hear a different change with a different curve.
  • Appreciate what would be optimal, and last but not least,
  • Realise what is a reasonable price.
 
Logarithmic potentiometers
A log pot has a resistive element that either 'tapers' in from one end to the other, or is made from a material whose resistivity varies from one end to the other. This results in a device where output voltage is a logarithmic, (or inverse logarithmic depending on type), function of the mechanical angle of the pot. 
Most (cheaper) "log" pots are actually not logarithmic, but use two regions of different, but constant, resistivity to approximate a logarithmic law. A log pot can also be simulated with a linear pot and an external resistor. True log pots are significantly more expensive.
 
Those and many other questions are constantly discussed among musicians and on forums, the most common problem is the working area or effective zone – the rotation of potentiometers in which we hear the change. There are a lot of frustrated users reporting that most potentiometers react - everything happens in 1/3 of rotation, app 35%. Outside this zone, the rotation has insignificant impact on function, there is nothing we can hear as change.

There are a lot of frustrated users reporting that most potentiometers only react in 1/3 of the rotation of the pot.  Outside of this zone they can hear no further change.
 
 
 Another disturbing situation is the adjusting or changing by decreasing or increasing the volume. What can happen is, you rotate the pot but hear no change, or, you rotate the pot slightly and the volume drop is enormous, the sound cuts off abruptly and your sound disappears. Being on stage playing and adjusting the proper volume is tricky and stressful, everything has to be done quickly and with precise rotation. To avoid all this some prefer playing with the volume on full, no risk of disappearing. But we all know the sweetness of sound is with the volume backed off a bit.
 
To overcome these frustrations, we offer a solution.  Here it is, a new Tone Up volume potentiometer with evenly increasing volume. To make the control easier and user friendly we developed a potentiometer with a new “hearing taper”. A simplified explanation would be like this. Knowing that most potentiometers react in only 1/3 of rotation we take this as a starting point.  We have magnified this portion of the effective zone and made it react in larger rotation %, to greater than 85%.  
So, the effective zone is much larger, and you can hear the volume change during rotation. This provides an easy way to control the playing dynamic and control the sound with a bit of volume roll off.
