Stomp Boxes Subject description: Anything general stompbox-y in here! |

Stompboxes are a source of inspi-/fasci-/frustration. Let's talk about em in here! I want horror stories, trciks, tips, dos/donts, stories of pedals you've bought, ones you should've-could've bought, ones you want and ones you'd like to warn us against. This is meant to be a pedal-schmooze.

I wanted to do the talking guitar effect in real time and it may be a long time until i fit any music hardware into my budget, so I gave it some thought and realized that the line-in jack is stereo, so it obviously has two channels. The guitar only takes up one channel, so I reasoned that I could build a little microphone / guitar DIY box to send the guitar in on one channel and the mic in on the other.
So I built such a thing, well actually I already had a box with some jacks and a battery compartment anyway so it didn't take very long to build. I put in a quad opamp to boost the mic and guitar signals to line levels and after a little trial and error the thing actually works!
The only problem is that the new setup with the box and a real-time ChucK program, the output signal has the guitar prominent and the vocal effect very subdued. I think this is because the mic is very sensitive and it is picking up the sound of the guitar strings themselves. That or the high gain of about 500 required to boost the mic signal is picking up some of the guitar signal from crosstalk.
Actually I just realized that I forgot to put in decoupling caps on the supply rail, so it probably is crosstalk. I'll tinker with it a little and see if I can improve the situation. It's a good start anyway. _________________ "Let's make noise for peace." - Kijjaz |
