H&G Amplification is an manufactory that designs and manufactures music amplifiers, speaker cabinets and boutique guitar effect pedals.
Well, again, we present a very simple circuit. As is also shown in the drawing, few parts. The circuit is based on a dual operational amplifier RC4558. But this is only half used, so there is only one using the op amp. Alternatively, you create an active tone control in the second operational amplifier section.
While playing the guitar many times there is a problem that unwanted noise can appear. Hence the need for a guitar noise gate. It happened specifically to a high-gain circuit is very sensitive to the surrounding radio signal.
