I like Guitar very much and taking classes and I got new yamaha FSX315C Electro-Acoustic Guitar, it comes with electronics and audio output of 1Kohm impedeance, So I thought I could make one small preamp with OPA2134 JFET opamp, so that we can use it with a normal power amplifier.
I soldered 3.5mm female stereo sockets on both sides of amp as INPUT and OUTPUT so I had to use 1/4inch female to 3.5mm male connector. I have connected the preamp circuit to my PC and recorded few tracks I have played using audacity software.
I hope you like it.
I will add few things to the circuit like Equalizer thing and post the schematic. Thank You
