Here's the update on this one. I am in the middle of building up the last prototype. The first build up above is an 8-stage phaser based around the old Maestro one. It has switchable stages 2-8. However, after I built that one, I found out that I REALLY LOVED subbing in the univbe caps in four stages. It sounds f'n AWESOME!
The problem is fitting that into the existing 8-stage design proved to be difficult, at least if you want to switch between univibe and phaser modes.
What followed was a freakin hard time of figuring out how to integrate the two ideas. What I found was that it was pretty near impossible to fit 8 switchable stages AND the univbe mod into a 1590BB without making some serious comprises in the layout.
So, this newest version is 6 stages and lets you pick 2, 4, 5 and 6 stages and uses a 4PDT to toggle the phaser and univibe modes in the first four stages. It also might have some cool blinking lights.
Anyway, I'm giving all this detail just to illustrate the process a bit more. LaceSensor mentioned a few weeks ago that transparency in the project development would be welcome, so maybe I should start up a new section of the forum that explains the process I go through in working on things...as a teaching tool? I dunno. Feels weird to say that!
