Anyone else have a Shin-Ei Vol, Surf, Siren, Hurricane, Wah?

I bought this on E-bay and it arrived today.











Temp wired a good battery snap to try it out in it's present condition.

The results were... not good... it's gonna need some work. Yay!

What the hell do “surf” and “siren” do? I associate surf with a wet Reverb. That circuit isn’t Reverb.

siren maybe like a siren's call? screaming woman tone or banshee tone.

Surf makes the sound of... well... surf, kind of a hissing whoosh you control with the treadle.
You know... ocean surf... waves coming and going....

Siren is a cheesy oscillator, it's the button above the treadle.
Step on the button and the oscillator ramps up, let go, it decays.
Bad emulation of a siren "wail".

Hurricane, or "Typhoon" on the schematic is sorta like Surf, but at a lower pitch.

Ok .. I get it now.. I remember Sears (Silvertone) made a pedal that produced an “ocean” noise in the late 60s.

I remember those pedals being used when I was a kid .... long ago .... they were cool and could be used, say, *once* a night ... after which they lost all novelty value

Basically a Wah, which with simply switching can become a Volume pedal, same thing exists until today.

The other possibilities were "extras", as I said usable "once" under penalty of becoming boring repetitive.

Wah quality was not too high , probably cheesy low Q coil made out of a transistor radio OT or similar instead of a "real" ferrite high Q inductor, so effect was not *that* noticeable, certainly no Cry Baby there, so "to show it was working" injected white noise helped, the noise generator is a Zener made out of a reverse biased transistor BE junction (yes, real Zeners were expensive)
Siren is actually that, a variable relaxation oscillator.

Here´s a free sample of early Argentine Rock, where the Siren is (appropriately) used at the beginning, for about, oh ... 15/20 seconds ?

Thanks JM, I knew you'd remember those...

I got this fixed up a little.

The blue caps are MLCC 10uf to replace the 10uf electro's
The one white cap is a 470nf film to replace the 0.5uf electro.
And a new 470uf electro for the power rail to replace the stock 220uf.



New wah pot and a little re-wiring.



Got rid of the battery snap and installed a power jack.



The wah sound is not half bad. I like it.
Good sweep and range.
It sounded horrible before I replaced the caps.

The other effects are cheesy at best.
I assume they are working as originally intended...

The Surf and Hurricane are controlled by the treadle.
The siren is not, but it is available at any time.
The volume pedal function is not great, I'll never use it.

The Wah I will use.
I can't think of any time or place where I would use the other effects (surf, hurricane, siren).

This was fun, I like fixing up old stuff.

Those pedals were all the rage when I was in high school. Some of them used a cam assembly to rotate the pot, rather than rack and pinion. Th one thing I never liked about themwas that the order of fuzz and wah was always fixed, If course, if I ever came into one, I'd now know how to mod it to flip the order.

I came into a Korg Mr. Multi pedal yesterday. Slightly more recent vintage than your combo fuzz/wah/FX, but not by all that much. The pedal is essentially a wah and phaser that one can operate directly like a wah, or use the foot control to vary the speed of an LFO sweeping either the wah or the phaser. A decent wah sound and phaser sound. It also has what they call a "double wah" mode, which sounds a lot like the old Schaller Yoy-yoy to my ears.

Love those older combo pedals.

I used to use a big chrome Morley Power/Fuzz/ Volume/Wah that had an AC power cord on it. Was great when it was new. Could NAIL the Mick Ronson sound...

I cleaned up the circuit diagram a bit.

This should be easier to read.
