Mad Bean Stage Fright. This is a clone of the Maestro Phaser with an option for 5 or 6 stages. It’s an OTA based phase shifter.
This sounds really good. The difference between the 5 and 6 stages is very noticeable. Overall a very musical effect.
I built this from a madbean pcb. The layout was great and everything went together well. I drilled a 125B sized box following the drilling guide but, couldn’t get it to fit in the box! The jacks hit the tops of the chips. I’m guessing that this because I used sockets. There is probably a mention of this in the build notes that I overlooked.
In the end I drilled a 1590BB sized box. Which worked very well. I think I like this better than the 125B size.
Here’s an image of the Casualty 4 Phaser. Wired everything up. After figuring out that I had forgotten to connect the ground wire from the jacks to the board everything seems to be working. Initial observations. The Shape pot seems to do nothing. The Width pot seems shape the soft triangle into a trapezoidial square wave. The phase sound is pretty rich. Need to test some more…
