ROSS Flanger Schemo?

[Joe Kramer]

Hi Friends,

I've searched, but this schemo doesn't seem to have shown up anywhere online yet.  Any help in tracking it down much appreciated!

Regards,
Joe

I have one of these old Ross's but it had a weird sweep that I couldn't fix so I stole the SAD1024 stage bbd out of it which was SOOO Graciously SOCKETED as stock.
anyway I don't remember if I ever tracked a schem but in case you don't know , the homewrecker site has a real good pic of the pcb on their Ross Flanger page that one could very easily trace a schem from , IF one was so inclined.
good hunting

I fixed a friend's Ross flanger a while back, it was the BBD, but I had found a schem for the MXR flanger and as far as I could tell, it matched his pedal part-for-part. (I didn't check the whole pedal)
For the most part, Ross cloned MXR designs, and added some tweaks to some (distortion, compressor)

Hey Kid: Thanks for the homewrecker pix, that's helpful.  The sweep on the one I've got is a little weird, but it depends on the setting I think.

Hey Ed: Thanks for the MXR tip.  I found this schemo:

However, there might be some question as to it's accuracy.  Maybe someone's out there has a line on the factory schemo?

At any rate, the MXR will probably work well enough.  The Ross unit I have, from what I gather, was not made in the USA (it's the black one), and it's been pretty well-abused.  In spite of that, it sounds great--reminds me of my long-lost yellow MXR chorus at some settings.  Since it was cheap and has little resale value, I intend to do some upgrades: toroidal power xfrmr,  extra PS decoupling at the op amps, maybe a few cap and op amp upgrades.

Thanks again for your help!

That looks like the schem I was talking about. It should be reasonably close to your pedal.
