  • scotchandy What is the OP voltage when a 150mV signal (1uA) is fed into a pre-amp with a 40dB gain. Can this be calculated with just these figures? Oct 01, 2013

Hi all, I'm building a pedal for a college project. I read and printed off the great walk-through you guys posted on here and thought it was a good help. (the guidance for beginners thing). I just want to ask one question that was covered in this report - just for absolute clarity. I used a preamp circuit (google "velleman-kit K1803) in my design to boost my guitars OP up to a workable level - Im using mains power (stepped down and rectified correctly, smoothed and protected too) - are the grounds in the sig in and out of this preamp definitely supposed to be common to the negative sleeves on my guitar and amp cables and my (low voltage) negative effect power terminal? I know that your report says this quite definitely but i am a panic monkey and just need to be totally convinced... can someone give me a yea or a no. Cheers.
