Review on Nobsound Precision Passive Controller Preamplifier by Jay Aukuso

ALP's are some of the best, prettiest potentiometers on the market and are used in thousands of dollar amps as well as a plethora of professional gear, and you really feel it with this knob. Basically just buy this piece yourself. costs around $35-40 from parts suppliers. So this little passive preamp is a pretty good deal. they probably make next to nothing of them after all is said and done. We recommend.
