Hi,

I need some help identifying this Small Stone:

The casing is v3, but the PCB clearly isn’t! It’s also not a v2, but it sure looks a lot like it.

The PCB has no writings on it, except for ‘EH-4800’ on the bottom. I need to identify the pedal and find a schematic to fix the volume drop and replace the slightly burned resistor, which is the first one after the 9v connection to the board:

Has anyone seen this version of Small Stone before?

-tnx!-

Fender&EHX;will know I’m sure, he’s asleep in the USA at the moment though, he’ll be around later. :thumb:

You dare invoke Fender&EHX;when The EH Man is around? :nono:

It’s likely an Issue H board (5 op-amps / 4 transistors). Essentially, it’s the same as the Issue J, just earlier by a year or 2. The burned resistor is a 47 ohm.

What’s the date code on the pot? I’d like to add it to my list.

Does anyone have a schematic of the Issue H? http://www.ronsound.com has one, but they want $5 for it…

I’ll have a look at the pot code this evening and try to get better pictures of the front and bottom of the PCB.

Thanx for the help so far!

Hey, just a crazy thought: there are “F” markers on the PCB… This won’t have anything to do with an “Issue” of some kind?

RonSound is me. The small charge helps me to buy more schematics and pay for my hosting. If you went to musicparts.com they’d charge you $15.

I don’t think the Fs have anything to do with Issue.

Oops!

Well, I just thought that if the schematic was present in the public domain, I don’t have to pay for it. I also thought that if it turns out not to be an “Issue H”, I’ll have absolutely no use for the schematic…

Here ya go:

And the bottom of the PCB:

I just purchased the schematic from RonSound, so soon I’ll be able to tell if this really is an ‘Issue H’ Small Stone…

That pot is a CTS, made in the 30th week of 1979. I think this SS is exactly the same as mine, I’ll check later.

I have that same version of Small Stone.

I love the way he said ‘invoke’ like you were some spirit or something!!

@Fender&EHX4ever;and Ned Flanders:

Did you fix the volumedrop on your Small Stones?

Mine never had a volume drop issue; but I’ve heard from many people that this is a common problem. So many variables come into play with different guitar rigs – different pickups, different cables, different power supply configurations, not to mention completely different effects sequences. All these can contribute to the issue. I run into this problem with my Flanger Hoax. The volume drops in some configurations, and doesn’t in others. It clips when I use high gain humbuckers, and doesn’t when I use low output single-coils. I solve this issue using 2 different compressors – the White Finger and the Black Finger. They are sequenced to solve my volume and clipping issues.

Yeah mine has no volume drop either, I think a lot of people mistake the smothered phases effects for a volume drop personally, the same can be said of the pulsar, it clearly has no volume drop yet people complain of this.
