Dan Armstrong - Yellow Humper (early version?)

Postby Professor SourTone » 12 Feb 2008, 11:46

Which version is this?

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... otohosting

This is an Armstrong Yellow Humper. It's just plain "Armstrong" rather than "Dan Armstrong" and made in the UK. I ask because I have a similarly marked Orange Squeezer. It has some age, predating the non-Armstrong reissues.

Does anyone know the sequence of manufacture of these boxes? Armstrong, Mutron, reissue etc?

Maybe it is a Pre-Mutron Version.

It seems likely, but hard to know for sure. Funny how the seller thinks it's the "British version of Mu-tron's Purple Peaker", which I also have and is a different effect.


I think I've posted this in the wrong forum - should probably be in Stuff Seen for Sale...

If you have one, how about guts ?
Or at least what is written on the IC ?

With that information it is much easier to date the unit.

I've got a backlog of guts I owe you guys. It will be a few days, as my house is still full of builders...

Don't agree - valid thread - had never even seen these plain "Armstrong" boxes before. I backed up the images for when they go offline.

good thread, really.

Looking around, I find three UK variants (at least)

No Dan, Made in UK on the back
Dan, Made in UK on the back
Dan, made by Wareham Electronics on the back

The Yellow Humper was a Purple Peaker revoiced for bass guitar (I asked at the DA website). ROG (aka homewrecker) already had the PP with mods, and Brian Tremblay came up with this ...

That´s right.....

but the schematic shown doesn´t represent the yellow humper.

There are some original Musictronics schematics around (never forget the index)

Yellow Humper factory schematic (1975)
Purple Peaker factory schematic (1975)

Big question on my mind:

How does it sound?

As a bass player I would love another "specific" effect on my bass!

FSB-member "ichian" made a complete analysis (of both units) here:

I never said it was the original schematic. The original YH sounds very like the PP, so the schematic I showed was a revoice to our tastes. The basic schematic is the same, the values are different for a different response. You can use the vero layout with the original values. Or not. Your choice.

oh, oh, oh..... sorry.....

I only wanted to avoid confusion and mentioned it.
Now we have a link to the factory schematic and everything should be ok ?
