The Goodrich H10K Active Volume Pedal
The Goodrich 10K Volume Pedals look like the rest, but looks can be deceiving. Several features put them in a class by themselves. One important difference is that any value pot from 10K to 500K can be used if it is a high quality pot with a logarithmic or audio taper. The buffered circuit results in the most minimal frequency loss obtainable, extremely quiet operation, and a total harmonic distortion of less than one tenth of a percent. The Goodrich H10K and L10K also offer up to 3.5 db of gain. In addition to these very important advantages the use of very long output cable is possible without tonal loss. Two low impedance outputs are provided; so you can drive two amps, or use one for your amp and the other for a tuner or direct to mixer application. The volume taper has also been improved to be very linear from full off to full on.
The 10K Series requires the use of a 9V Battery. The circuitry is designed for long battery life.
The Goodrich L10K is the low profile version of the H10K. Although the circuitry is identical it is generally preferred more among pedal steel guitar players for the low profile design.
