Newsletter Sign up for the AMZ Guitar FX Newsletter for free information, tips and tricks on building guitar effects circuits and how to use them.
This is a “low traffic” newsletter, so you don’t worry about your inbox filling up.
Update: Okay, I’m planning more than just a newsletter. How about some podcasts, and videos, or maybe schematics just for subscribers. PC Board giveaways are also in the works. I’m not sure what will be the final outcome, but you don’t want to miss out!
I have updated the LED calculator to show the wattage required for the resistor that is in series with the LED. A 1/4w resistor should be enough for most stompbox indicators, however, I am currently using a lot a 1/8w resistors and this allows me to verify that the resistor is operating within safe limits.
A couple of years ago I posted an article about a revised version of the Little Angel Chorus, which uses the PT2399 delay chip. I finally got around to doing a few mods on it to see if I could further improve the sound.
This is a pre-assembled jfet buffer. It has a clean, transparent sound and can be used in numerous ways on your pedalboard or even used to mod existing effect pedals. As can be seen in the photo, the board is not much larger than a postage stamp.
