Title: The Funky, 70's wah pedal, I want to make! Any advice, would be helpful!
Post by: tone seeker on October 03, 2018, 01:19:20 AM
 I picked up a old wah pedal, that didn't work
But, was perfect, for extra space.
I was wanting a Jimi Hendrix sound
For the wah, which I have a Guitar
PCB board for. Just need to get the
Appropriate parts for that.
so I think I have that figured
Out. I wanted to add fuzz, and phaser.
I am really looking for that "Whose
That Lady" sound.
From what I've looked up, a Univibe,
Or phaser, added with a Big Muff,
Can get close to this.
So I was wondering which would
Sound better. A phaser effect, or
The MBP Stage Freight, wired for
Univibe.
I could just go with a Big Muff for
Fuzz, but I was thinking about using
A fuzz effect, put out by Guitar PCB,
For that 70's "In A Gadfa Da Vidda"
Fuzz sound.
Any advice, on different effects, or
Special parts to use would be helpful!

For "Whose That Lady" in particular, you'd want the Lectrix FX "Countdown Phaser". Its based on the A/DA Final Phase, a CMOS phaser with built in overdrive effect.

note: The actual effect used in the recordings are hhypothesized to be a Roland AP-7 "Jet Phaser" and a Roland Bee Baa fuzz, injected directly into the recording board. Neither of which has much shelf space in the DIY world.

I have read about the Roland Jet phaser, and Bee Baa fuzz, But I watched
a guy on youtube use something different. There was a wah pedal, going to
Maestro phaser, a Big Muff, than a Rotovibe.
I was hoping I could wire each circuit separate, with foot switches. I really
want that fuzzy, high end, phaser sound. The Countdown Phaser sounds
like it could be the right direction

I guess the Isley Brothers were time travelers. "That Lady" (the funky version), was recorded in 1973. The Roland AP-7 came out in 1975.
As with pretty much every Phasey-sounding tone that nobody can figure out, it's almost always a Maestro PS-1a. That should be the first guess every time, but it's always the last thing considered. Whenever in doubt, always guess the Maestro PS-1a.

Yes! the Maestro PS-1a is what I think really brings the tone home! Does
anyone make a pcb of this? Or a vero layout?
I was thinking the MBP Stage Fright, may be close option

Another good one for you might be the Korg Mr. Multi.

DEFX has them  ;)

Stage Fright uses OTAs, PS-1A uses a sextet of matched FETs.

Juansolo has a etched PCB layout for the PS-1A, Haberdasher can etch it for you, I believe.

 Thanks for the input! I'll do some research on these effects, and go from there!
