Anyone else use a AnalogMan DOD YJM308 741-"mojo" MOD?

[telefunken]

I bought this pedal years back and didn't use it much. Now that I'm BACK into Teles I pulled it out. It sounds great. It rounds out some of the high end but the Tele still sparkles(hard to explain). I found my self playing for hours with it yesterday. It's true-bypass and they added a indicator light also.

I didnt know he did these. My freind has an original gray box dod 250 he bought new, its a great pedal. I guess it gets a bad rep because people think they are just for Yngwie fans but it works great with a tele into a clean (bright)amp.

What! No one owns one of these

I just got one today... haven't plugged it in yet; I got it to use with my Charvel for Yngwie tones (got a SD Fury in the neck)... but I'll give it a run with the tele as well.

Bad rep? those old boxes are highly acclaimed, sought after and duplicated...absolute classic! Check what they fetch on eBay.

Yeah, I have a scratchbuild of one. I couldn't imagine not having one of those, a D+, or a Crowther Hot Cake (all 3 are fairly similar circuit-wise).

NJM (they took over ownership of all the JRC stuff like the 4558 chips and such) makes their own version of the 741 that has a much lower noise floor. Seeing that the 4558 is kind of like a dual 741, I guess it is only fitting that there is a "single 4558."

The NJM/JRC 741 just takes a good pedal and makes it better. I've also done some tweaks to the OD 250 to make it a little more "21st century application friendly." I think Czech-One-Two implemented some of them if you want his take on them.

The 250/D+ are two of those pedals that are just simple in all the right ways, and the rest is up to the player to try and harness them (and not go nuts with gain IMO). I LOVE the absence of a tone control, too!

The full vintage mod he does with the 741 requires rerouting the opamp connections in replacing the 4558 in the reissue 250 (or the YJM version). He also does another mod using a 1458 chip, which drops right in to replace the 4558, it really is a dual 741 (the 4558 actually has better specs and sounds different). You can easily mod the reissue OD250 by putting a socket in place of the 4558, replacing the chip with the 1458 (or experiment with other chips for different sounds), removing the 25pf cap they put in to decrease the hi-fi tonality of the 4558, and replacing the input cap with the vintage value (as I recall the reissue has .01uf, vintage value is .001uf). This will get you 99% of the vintage grey OD250 sound, and is easier than the 741 conversion.

I've got a pair of 1458's kicking around, with no real use for them. DOD used to put them in their pedals at least up thru the 80's.

I had no idea that the RI has a dual in it! Heresy!

I'm actually trying to get to one of my modded SD-1 monstrosities tweaked that has the 2nd op amp stage set as a unity gain buffer - I want to yank it, bypass it (stage 2), and drop a LM308N in there (with a similar pair of HP filters like the Rat). The big issue along with rerouting the pins is that the LM308N gets the external compensation cap across pins 1 & 8, so it could like really clunky if I don't take my time.

I'd also like to re-wire a DS-1 for a LM308N, since it only uses half of a dual as well. That would require rebiasing Q2 cooler, or it would sound like cities imploding.
