Moog Rogue - Tackling the foam

Post by Toris » Mon Mar 02, 2009 9:43 am

The issue with the internal foam in the Rogue is well documented but just in case anyone on here owns one and hasn’t tackled it, I thought I’d have a go at my recently acquired Rogue over the weekend. Before I start I really don’t need any of the well known synth techs (or their wives) launching a scathing attack on what I’ve done, but I would welcome any constructive criticism or advice on how I could have done it better. I’m not a synth tech, nor am I trying to steal their business, I’m just wondering how other owners have tackled this problem.

I managed to ‘catch’ the foam on mine before it had completely turned to goo so that was a bonus:

The old foam removed with a scraper and Isopropyl alcohol:

After masking, I primed and sprayed the inside of the case to hopefully prevent corrosion. I also fitted some new foam with slits for the sliders. (I also cut round discs of foam for the rocker switches):

Image

Keyboard assembly was stripped and cleaned:

Back together:

Err...now what?

I'm not an expert on the foam either, but I must say that looks fantastic.

Hmm, nice job. What's the foam, and where'd you get it? Might grab some.

Nice job!
I have done the same on a MG-1. The foam had turned in to goo. It was all over the electronic components and deep into the sliders. I used lots of alcohol and q-tips.

I used this stuff. It's quite high density and nothing seems to come off it i.e. into the sliders.

The seller had some black at the time, worth an email to see if she's got any more.

Any kind of foam is not a stable plastic - never put any foam in a synth. It will degrade in as little as six years. If a gasket is still wanted, nomex (carbon fiber), thin polycarbonate sheet or anything stable would be much better. Felt is also a no-no. :(

Toris was indeed lucky that his hadn't completely liquified yet. Disassembling sliders to get black tarlike goo out of them with solvents is no fun. :x

I've had a couple Moog Rogues that suffered this malady.

MG-1s and Opus3s are in danger as well.
Best Regards, James

The stuff I used was a form of styrofoam. They use that in buildings and it's lifespan is comparable to that of the building.

I'll still keep an eye on it though :-)

What did you use for cleaning the keys? (they really look clean)

My JX-10 could use some cleaning...

The key tops were taken off and just washed in mild soapy water (rightly or wrongly). I only had 32 keys to do not 76!

Haha that takes a lot less time then!

I will try that. Does one really need to take off all the keys for cleaning them??

I took them off as it wasn't too much hassle. You can buy proprietary plastic polish on ebay. It's excellent for removing fine scratches and and cleaning key tops. I've got some of this stuff:

Still hard work but easier than taking 76 keys off.

Does your aftertouch work well on the JX? If not, it might be worth taking the keys off to repair that and clean them while you're on.

All the technical aspects are fine on mine, but cosmetically it deserves some care I think.
I just need to scratch them clean with some polish, that's all!
Thanks for the recommendation of plastic polish, will look for it in stores today!

Beautiful Moog btw :D

Thanks, I really like the Rogue. I've always thought it would be a bit too limited. Having owned Prodigy/s in the past, it seemed even more 'stripped down' but the contour sync, pink noise and s/h are great. Tuning is also stable as a rock.
