For my own use, I made a calculator for finding the frequency of an oscillator using the classic LM555 timer chip. You can find it in the Lab Notebook or here is the direct link:

Three dual op amps and a single. More info and images in my Instagram:

Another pedal prototype in a metal electrical box from around 2000. This box is interesting because I did not have a metal cover for it, so I made one from a piece of aluminum diamond plate that I had in my shop.

The prototype of the Q&D 1 compressor. The schematic is still on my web site somewhere. It used the SSM2165 vca chip which is unobtanium these days.

Another ancient pedal from the boxes in my garage. This one has the same type LMB folded aluminum enclosure. It also uses the cmos switching system with a soft-touch footswitch.

The heat wave has passed (temporarily) and I could go back in the garage and dig through the boxes. Here is another pedal from decades ago.

This is a dual op amp booster that was the predecessor to the dual op amp pcb that I sell on my site. I’m not sure how old it is but it pre-dates the internet! I used this pedal sometimes when playing live.

A tap of the footswitch toggles between the two channels that can be set for different gains.

I was in my garage looking at a bunch of boxes that had been stored in the back for years. I found two boxes with a couple of dozen guitar pedals in them, from classic boxes to prototypes of my own designs that I had built, and some I had even forgotten.

This is a Brontoboost that I bought directly from Joe Gagan around 2002. I contributed the tone control design and a couple of other circuit snippets that I sent to Joe when he was first working on this pedal. The front panel features a custom painted and engraved art panel that is very cool.

I’ll be posting other pedal images on my Instagram page: https://www.instagram.com/amzfx/

I just noticed that the various versions of the Stupidly Wonderful Tone Controls are now available in the online TSC calculator. This is a great resource so you should check it out if you are interested in tone control performance!

Not related to pedals, though it might be useful for box decals, is my new gallery of images that were created with the Midjourney AI program, You can see the images at:

Not sure that the site works 100% yet, but you still should be able to enjoy the pix. Thanks for your interest!
