I had wanted build a compressor for a while now. But had never actually gotten around to actually making one. A few months ago I etched and soldered a a Saffron Squeeze, which is a Ross clone. Somehow I had not actually finished this before I found stripboard layout for John Hollis’ Flatline, which jumped ahead in line.

I have it all in the box. I just need to wire things up.

Here’s a Wah probe work alike. Thought this would be a fun build. Someone gave it a good review over at DIYStompboxes so I etched up two boards. just got the parts in the mail and soldered the last parts into the board last night.

Here’s a picture of the populated board. This still needs the LED/LDR. I need to create an enclosure and figure out what to do for an antenna.

I found some good information on trimming the N570 to help remove unwanted distortion. The chip contains to two identical sections which are mirrored on either side. Pin 3 and 14 provide an input for a control voltage for the gain cells. Pin 8 and 9 provide a distortion trim fro the gain cells.

Not sure exactly what is happening here. I suspect that trimming voltage of 3.6V is related to the internal bias of 1.8v used by the NE570.

This is the Tremolo-Matic X from Stompboxology. I’m in the process of building this for “Jonny” who I met at the last DIY Swap meet. He gave me this box to put it in.This project is coming together nicely.

Here’s an Ugly Face I built. I used PnP for the design on top. The transfer was a imperfect. But mostly worked. I’d really like to find a reliable toner transfer that works on these metal boxes.

Here’s the current projects. Two Echo Base and two Casualty 4 Phaser shifters.

I found these old school layouts by Andy. These look like fun to build the layouts just scream mojo. I think I will have to etch a few of these up and build them with carbon comp resistors and ceramic caps!

Andy aka “Dragonfly” posted like mad on the DIYStompbox forum for several years and then mysteriously disappeared. He was prolific. Check out his gallery. Lots of great info.

Looks like one of my Ugly Face’s made it into the “Art of the Stompbox” exhibit at the Museum of Making Music in San Diego.

Wow, you must take a look at this site. These are the most amazing applets.

Here’s my take on the SHO. With crackle free knob. Adjust the value of C3 to create a range boost.
