    Hello, For a better tone control for your guitar circuit, have a look at section 8 of this page: https://sound-au.com/articles/eq.htm There are the fender and marshall tone stacks shown. This could replace the 10k pot and C29. This is the music related section of that site...

    Hello, Did you already take the circuit apart? Perhaps the capacitor C28 has a to small value and only high frequency signals are amplified. Raise the value of C28 to 10 μF and see what happens. Bertus

    Should a line tester light up when inserted into grounding socket?

    Hello, Wich line tester do you use? I would say that there should be no power on the ground connection. The ground connection is there for safety. Read the book in the link: www-d0.fnal.gov/~hance/doe_esh.pdf Bertus

    A Stretch

    Hello, Just use the film capacitors that you have available. No need to buy more components. When an electrolitic capacitor is mounted the wrong way around, some kind of diode efect may happen. This can have bad effects on the capacitor when the power is a lot, but not in low power audio...

    A Stretch

    Hello, The pins on the bottom of the potmeter are for a on/off switch. You will likely hear a click when you turn it fully left. You do not need them at the moment. Just use the three loops on the side of the potmeter. What opamp do you want to use? In post #6 I posted a datasheet and pinouts...
