Hello I'm working on a circuit diagram of the nos pedal that I have. It's my first time reversing the circuit, so I'm not sure if it's made right Is there something weird that see?? I think I did a good job on the gain side, but I'm asking because the input buffer looks weird! It's still...

In the picture above 1. 2b 5 (lying) tr https://www.alldatasheet.net/view_marking.jsp?sField=0&Searchword=2B&list=41 2. E3A diode https://www.alldatasheet.net/view_marking.jsp?Searchword=E3A 3. silicon diode I'm just looking for the exterior, but I'm not sure if it's 1N4148 I'm looking for...

Is the two clipping circuits the same? Ultraphonix is called a Zendrive copy, but the clipping circuit looks different. A ultraphonix B zendrive with single bat41

It's a circuit related to signal blending using opamp In A, we amplify the signals from opamp-2 to control the volume In B, when combining signals, A adjusts the volume separately, so the blending ratio keeps changing according to the volume of A, so I'm going to modify this circuit I want to...

I'm trying to blend clean and zendrive circuits using clone buffers with the circuit shown above, but the blending knob is only hearing beeps noise toward the clean, so did I do something wrong? There is no problem with individual use of buffer and zendrive. However, there is noise in the...

Can you infer which circuit this schematic is original from? It is a 4-knob board and the original is written to use opa2134. (photo jrc072)

I recently became interested in the 320design brown feather pedal and am trying to make a similar pedal. Is there any related information? There is no information, perhaps because it is a Japanese-made pedal.

I want to modify the ultraphonix circuit and make it into an hrm version. Does anyone know anything about it? Even a picture of the circuit diagram is difficult to find.
