I have a Sound Fuzz-Wha-Volume (don't remeber the model number). The circuit is a Cry Baby copy, it uses a double pot (one half is for the volume) driven by a steel lever. It's one of the worst whas ever built by man. In fact, it's not "wah", it's more like "___ah", the low end of the travel is unuseable, the sound gets too quiet and muffled.

The fuzz part, IIRC, is like one of the CCDB fuzzes that were published in Nova Eletronica.

The footwitches are light duty cheap plastic DPDTs.

A picture would be great ;)

More photos of the ES-2 on:

I also took pictures of another brazilian pedal, the "Chorus" SuperOverdriver ("Chorus" is the name of the brand; it's just a overdrive pedal).

I can't find the Giannini superfuzz pcb, I think it went to the trash bin. I've got pcbs of two Giannini amps that I can take photos, the U65G (transistor with an interstage transformer) and a tube PA amp, the A101, I think.

Thanks! I had some bad pictures of the Chorus DW-A3, so I replaced them with your pictures :)

Here's the list of Brazilian brands I found:

Yeah, this thread could be split.

A note: the Sound ES-2 PCB pictures doesn't show the inductor, that I took off to use somewhere else. I'll try to locate the inductor and take a picture.

Looking at your list, I think Palmer used to make pedals in the 70's too (they made amplifiers, organs and tape echos, for sure). If I have any pictures in old magazines, I'll try to scan it.

I have a service manual with lots of Giannini amplifiers and pedals, and I also traced the chorus overdriver and the Sound ES-2.

Chorus Super OD schem:

I like the way the gain control is wired, less gain, more bass, more gain, cuts bass.

Sound ES-2 schematic, wha and fuzz

I have not included the switching.

Some Sound pedals and two Palmer echos, tape and digital.

I can't access the pic's link, if a larger image is stored there... maybe it's not the case...

Me and a lot of friends got Sound ES-? as our first guitar pedals. I really didn't find they usefull for a newcomer as I was.
Recently I tested one ES-3 and found some interesting uses for it. The Wah sounds really bad, not very juicy for my taste.
The fuzz is very nasty sound, what can be a very good thing when used apropriately.
The siren, well... it's a siren!
The repetition is very cool indeed, it's like an ultra-slicing-tremulo.
The padal fotswitches are very cheap and unreliable.
The expression pedal is good. So good that some years ago a friend gave me a ES-2 completely canibalised and I used it to put my Easyvibe on it and control the rate with the expression pedal.

The other effect pedals from Sound I never saw them.

A bigger picture would be great, but this is already fantastic information for me :)

I just can't read what type of pedal the ES9 is.

This Palmer is probably not the same Palmer from Germany, I'll have to search a bit more information about it...


Thanks!!!!

As far as I know it's not the same Palmer. The brazilian Palmer used to make organs, amplifiers (they used to make some very, very good tube amps based on Marshall models, including a killing Major clone), PA stuff. I think they are out of business.

Sorry for the picture, it's scanned from a book (the brazilian version of Ralph Denyer's "the Guitar handbook"), originally it was already small and blurry. Ican't read what the ES-9 is either!
