  • Causality 6 by Frequency Central

    Causality 6 by Frequency Central

    This is 4/6 stage OTA based phase shifter by Rick Holt of Frequency Central fame. Here is a link to epic thread about this and a 4 stage design over at DIYStompboxes.com. Here’s my build, which is working but has a couple issues that need to be worked out before it’s ready for prime time.…

  • Mini phase 45

    Mini phase 45

    I started this mini Phase 45 so long ago I cant remember when. It wasn’t working, so I pushed aside and forgot about it. I found it again, and decided I would get it working. There was sound but no phasing when the circuit was engaged. My first guess: the oscillator was not oscillating. I…

  • AionFX Qudratron a Lovetone Doppelgänger clone

    Here’s another epic pedal build. The Lovetone Doppelgänger is a phase shifter with lots of extras. It has 4 phase shift stages and two LFOs and options for all of this. The Quadratron is not a direct clone of the Doppelgänger. It’s faithful to the original but makes a few changes. Both are four stage…

  • Maestro Phaseshifter – Mad Bean

    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.

  • Tremshifter

    Dead Astronaut FX Tremshifter. Tremolo and phase shifter in one pedal you betcha. Rate for each yep. An LED for each you know it.

  • Madbean Stage Fright

    Madbean Stage Fright

    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!…

  • Casualty 4 Phaser MKII

    Just tested this one again. My mistake the shape pot is working. It seems to me that the Width pot seems to square off the LFO wave form as it is turned up. With Width all the way up the LFO seems to produce more of a square wave.

  • Casualty 4 Phaser working

    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…

  • Casualty 4 Phaser

    Here’s interesting phaseshifter idea I found over at Circuit Workshop. The Casualty 4 is an OTA based phase shifter with two modulated stages and two fixed phase shift stages. This looks like a pretty interesting project. Looks like you can fit this in a B sized box but there doesn’t seem to be enough room…
