Customers are mixed about the volume of the electronic component amplifier. Some mention that the control is nice and simple, while others say that it cuts the power and produces little sound. The knob also affects the quality of the sound and produces lots of noise. Overall, the volume is a mixed bag and may not be the best choice for every customer.

4 Stars
It works but its not great at filtering out noise.
Got this to control 4 JP23.1 mono amps running through an RCA distribution block. If I don't have the knob at - or full tilt I'm getting ground noise. I've changed out RCA cables and RCA block and I still get the noise. If I remove this and just go directly to the RCA block the noise is gone. Gonna try a different gain potentiometer and see if that makes a difference. While it works I can't say it works well cause of the noise it introduces into the system.
