This might have been mentioned here before. I think the problem stems from English/metric conversion. In the US, the standard guitar cord uses 1/4" plugs, and the old mini-jacks used 1/8" ...

Thanks for posting again, catweazle! The source code for Nintendo looks interesting, especially the 12 db/oct filter. Any sound examples available to hear this filter?

There are all kinds of sound samples earlier in this thread. Yes, the PIC produces the sound directly using PWM through a simple RC filter. I've also been doing a lot of dsPIC programm ...

I think one of the four control switches might have to be in a certain position for the strings to play. I'm not sure which switch it was, but I know it was not the vibrato switch.
