Meron kayang bentang cicuit lang nito?

Balak ko sanang gumawa ng para sa instrument ko pero hindi kasama lahat ng casings dahil bulky.. kung OK sana kahit yung essential parts lang para maikahon sa mas maliit..

You can use 2N5457 but you might need to change the drain resistor. In my case I used 1K5.

Mukhang maganda nga yan.. I'm planning to use it for my acoustic violin.
Medyo explore din kasi ako ng ibang instrument eh.

I need the reverb circuit aka (presence knob) at yung tuner nya.. Pero kung wala talaga siguro at package na iyan, baka baklasin ko nalang..

Would you prove then sir that this really sounds "tubey"? Guitar gadgets is one of my interest too. I have already this scheme but never done yet. I use the fuzzface of the tonebender., germanium transistors.

I am using it on an acoustic guitar that is using a piezoelectric pickup mounted under the bridge. In the case of acoustic guitar, I do not want tubey sound. I want to reproduce the natural sound of the acoustic guitar. This works fine for me.

However I have tried to overdrive it and looked at the signal waveform being clip. Indeed the clipping is soft clipping similar to what you can get from tube amp.
