Look up the Shumann PLL pedal schematic if you want a synth sound. It's based around 4046 PLL IC - which tries to match the signal's frequency and in a way also has a linear frequency output ( detected frequency output, let's say. Hooking up this output to any linear-FM VCO will make it a synth, essentially (shumann PLL originally is a weird octaver pedal, I'm sure even XR2206 will work just fine, but will need a bit of tuning to match the 4046 output voltage range and XR2206 input voltage.
I don't get why did you just hook up your guitar signal to FM input; Were you trying to achieve FM synthesis sound?

Here's an idea you can try - there's a company that started reissuing some classic analogue synth chips including proper VCOs, called Alfa Rpar. Their AS3340 could be interesting to use in a guitar synth, and you'd also probably want to make some sort of envelope follower for the guitar signal to gate the synth output - I'm guessing a full bridge rectifier feeding a capacitor would work

You removed a bit too much of the input circuitry:
There was a 2. 5V DC bias on the input of the opamp, which results in the audio signal being centered around 0. 5V on the input of the arduino.
In your setup, the negative side of the signal will get clipped of by the opamp and result in the distortion heard in your video.

son of a dude, I started learning the same song(take on me) at the same times as if we were connected somehow, when i saw you playing the first one i tried it and then i tried take on me, when i was done i unpaused the video and then you started playing what i was playing coincidence? i think not, where are the cameras scott

GreatScott, One of my favorite guitar effects pedal to use and to make is the chorus pedal. It's simple but the effect is dramatic. I suggest you could use PT2399 delay pedal, and modulate one of its pins to create a chorus pedal or use the old analog 'bucket brigade' ICs (80s tech) which creates a more pleasing sound.

now make a preamp for the other guitar from one transistor 3 resistors capacitor and piezo electric flat speaker
but what i really wanted to say, your effect box is tuned for low impedance preamplified signals
how about dryving it with low impedance electromagnetic pickup of an electric guitar?

for acoustic guitars, it's really creative if you could apply a reverb effect. It's the most difficult effect to simulate. Analog circuits would wither use springs or bucket brigade circuits, but digital techniques are also difficult since a lot of code is involved.

this was how I started with elctronics. by playing the guitar and assembling guitar pedals. Now I'm an engineer, I don't play the guitar nor make pedals anymore but I always remember my past. Passion and excellence.

Hi, I want to create a DIY guitar pedal (a Small Clone chorus, I've got the schematics and even the PCB layout but I'm a complete beginner and I am not able to create a proper gerber file. Can anybody help me?

Hey if you want to just record your guitar, there's an easy method: point your mic about a foot from the 12th fret
Avoid your tascam because it has 2 capsules pointing different ways
