Very interesting..... As you can see here:

there existed early Ross distortion in a small BUD-Box. The Funny thing is, that the pcb inside looks identical to the MXR-pcb´s:
http://i15.ebayimg.com/03/i/000/da/25/c077_1.JPG
The pots show early 1977:

There even existed a:
Ross Distortion script
with a very similar to MXR pcb:
Ross Distortion script inside
Anybody has more info on that matter ?

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.
Those are good sounding, and usually inexpensive, pedals. And yeah they're pretty much an MXR+. The tan box is the earlier version I believe, the later ones were black. There are a few minor differences in the circuits. To me the MXR+ has a lot more high end while the black Ross seems to be darker sounding. It's been a while since I've plugged in either of them.
I have two black versions. Nice little pedals. I didn't they had a smaller version. Learn something new everday.

I have a tan one and a black one, the black ones were made in Taiwan whereas the Tan are US made. The tan certainly sounds better. I will look for any differences between them.

Ive got a bid in on that one. Ive owned quite a few Ross Distortions, but never a narrow box version.
Ross made 3 dist-pedals.
Early US tan version with metal can uA741C, circuit similar to the early sript logo D+.
Later US tan version with a 4548 chip instead of the 741C, due to the different IC more middy sounding, soundwise more like the DeArmond Square wave fuzz.
Latest Taiwan black version, same circuit as before but with 3x1N914 diodes for asym clipping.
The last two versions have a 10n for better treble response across the power supply.

I used to have one of the made in USA large box ones. I thought it was a very good sounding pedal, definitely mellower than an MXR+. The reason I didn't keep it was that I wished it had more output so that it could have been used as more of an OD with the lower gain settings. Never tried any of the later versions.

I own a wide box Ross Distortion and love it - it sounds like a cross between a tube screamer and distortion +. I was contemplating modifying mine to include an LED, true-bypass and a boss style adaptor. Also was considering a Cat's Eye Analog Mutha' Fuzz (a Ross Dist inspired pedal). I had some free time yesterday (bad weather in the Northeast US) and built one point to point (using the above layout) and it kills.

CORON dist10 is yet another MXR+ clone with a NEC chip....

Hey, hey, hey..... more respect:
That´s bootweak, because it is tweaked.
Note the modified bias divider 51k/68k which gives a little bit more (symmetric) headroom.

Yup ... the CORON is nice at low to medium gain and best with single coils.
Volume needs to be almost max ....

I snagged a narrow box script Ross Distortion yesterday for what I though was pretty cheap. The pots date to '77 and it's a 1:1 Distortion+ clone.

That second model could be made in Taiwan too: IIRC those with a rectangle around "Ross" were already made in Taiwan.JHS wrote:Ross made 3 dist-pedals.

Yesterday morning I found out I won 3 vintage MXR Distortions: all block logo, 2x 1978, 1x 1980: I did low bids on 5 (all from the same seller) thinking I probably couldn't win even 1, but now I'll have 3...

More blurring of the MXR/Ross lines:
It even has the foamy crap the MXR boxes did:
Looks like maybe this is using a DIP switch instead of the internal pots on the full phaser circuit?
Must be of value to a Ross collector..I love the phaser/distortion Ross I have..

I´ve seen that auction already....
The pcb is 100% identically to a MXR Phase 45. There are no DIP-switches, the trim-pot is (like in the MXR phase 45) in the backleft corner.

What about the Phase R2? Also a Phase 45?

Did you ever do this mod or has anyone else? If so, I'd like some advice as I want to rehouse my BLACK box pedal and add an LED but I am not exactly sure I know how to do it - seems straightforward though. I think it is as simple as following this wiring diagram correct?samhambone wrote:http://www.aronnelson.com/gallery/main. ... temId=1365
