Why do none of my FX work?

[humbuck]

Thanks for all the help guys, I'll let you know how I get on I'm going to try fixing the fuzz-booster tonight. :?

IT WORKS!

The fuzz-booster that is. It has a good boost, with slight distortion and slightly compressed output.

Thanks for all your help! In the end It was the caps I was using - the ceramics I have from an old radio seem ok, but don't work well. I tried with the metalised polyester film (these from a television) and It worked. I've also built the "begginer" project (gus smiley single tranny boost)

Cheers for the help.....Now I am addicted!

Well....  I keep trying to use the big iron instead of waiting for the small one to warm up & soldering pads together. What an impatient dumbass, & I'll probably do it again 2-nite.

About the audio probe:
1. Does the jack have to be enclosed?
2. Does the effect need to be on or even have the battery connected?
3. The electrical tape is only to go around the cap, right? I mean, not the blue wire show in this diagram: http://www.geofex.com/FX_images/audioprb.gif

Sorry for the ignorant questions! :oops:

humbuck:

sometimes those ratshack capacitor assortments have caps in them that do not give you a voltage rating. Perhaps you were trying to use caps with a 5 volt rating and your power supply is 9 volts or something like that. Anyhow, glad you got it working.  :wink:

tonepoet:

1. I think it's better to use an enclosed jack, but it's not absolutely necessary. That way you could fold over the cap and wrap the whole assembly with tape which keeps everything secure.

2. The effect does need to be on and powered.

3. The electrical tape is to prevent the ground from touching the signal wire and to keep the cap from moving around too much and having the leads break on you.

Here is the one that I built: http://www.diyguitarist.com/PDF_Files/DIY-AudioTester.pdf

Hope that helps and I really hope that you get one of effects working.


As a general note, if you are using NTE parts, the transistors they sell are notorious for having different pinouts than the ones they are supposed to be "replacing". "Equivalent" to them is specs only, IME. And again, transistor pinouts can change between types. This is especially true of JFETs and MOSFETs - some are DGS and some are not. Run of the mill transistors seem to be pretty standard, like 2N5089, etc. Mark's suggestion about keeping data sheets for all the stuff you use is a good one. That's what I've been doing for the last year.

Great to hear that you got the booster to work. Now it's time to get the others to work, then start to build more things. This is really like an addiction.

Like an addiction? This is an addiction! :twisted:
