I've been looking in the program and googleing, but I can't seem to figure it out. Thanks, Jason how do you run a sound clip through your circuit?

There's was no problem really, I was just too much of a beginner. I have to click what I wanted to measure :) So I clicked V(OUT) and everything worked fine. The LM741 opamp thing. Is that a part of the overdrive circuit or is that something you always should add in in case you want to generate wave out. I ran a clean guitar recording through the overdrive and it sounded good for being a simulation in a awesome freeware software. Best regards Hi again.

Thank you. I am unable to help much these days because I changed jobs and cities last Fall. In a month or so, I expect to plug back in. I hope you can figure out your problem with the new LTSpice. That is probably a better strategy than trying an older version. All the best! Hi Eric. Thank you. I am unable to help much these days because I changed jobs and cities last Fall.

Very nice site. I want to learn more about guitar pedal building and your site is the best I've seen. However, I've been playing with LTSpice for a few hours now just to get used to it. Found AC128 transistor as well, don't know how much it resembles the real one though. However, I downloaded LTSpice today and tried DOD Overdrive 250, everything seems fine, no error messages... BUT it's all black in the .raw simulations. I noticed that I'm using LTSpice IV and it was updated today 1st May 2009. What a co-incident to get started with electronics :( Is there some link to the old switchercad III that you know of? Best regards from Sweden Hi! Very nice site.

I go over all settings and finally... maybe I'm supposed to choose visible traces for the plot? Whoopiiiie! I'm up and running. I just simulated 10k battery resistor/ voltage sag. Thanks! :) PS. It is possible to import netlists from switchercad to say... Eagle? Oskar I hit simulation and… nothing just black.

You can run a sound clip through your circuit, too. So you can A/B your mods. It gets cooler. You can run a sound clip through your circuit, too. So you can A/B your mods.

I took the DOD example and played with some mods and then I created a simple new circuit of my own. Cool stuff! Thanks This is awesome.
