I know nothing about how amps work, or how bright switchs work ( I self educated on a youtube video, if that counts)
Is this something anyone else has done? Do you think any decent tech should be able to do it? Ive only had the EMS for a few days, and while I like it, it just seems dark, or darker than I generally care for. I am playing through a Bogner 2x12 with greenback and V30 and a Splawn with creamback 75. Thanks!

If possible, I’d try an American voiced speaker first before modding. Greenies and their derivatives can be considered dark by some for clean sounds.
EDIT: For some reason I thought we were talking about the EZG, not EMS hence my comment on using an American speaker. For the EMS being too dark, I got nothing.

It's rare to hear folks think Marshall type amps are too dark, but it's possible, it's not a particularly difficult mod for a qualifier tech to put two different values on a switch to ground. The first question though would be where are you setting the controls? Let's see if there is an easier solution than modifying the amp, or if there's a preamp swap that could be done to get more brightness out of it.

Even Dr said it himself, he wanted to dial out the "harshness" that typical marshalls have - it doesnt quite have that sound anymore. I will try swapping out the preamp in V1, to see if that can help. I have tried keeping the bass and mids down, while still having some bottom end. I only play at home for fun, through a powerstation so I can get some power to the tubes.

I particularly like how the description of this amp says it doesnt have the persistent harsh treble...or something to that effect as I've found many marshalls to have a biting high end incredibly difficult to tolerate.
Why dont you consider a naga viper treble booster or something before letting someone gouge around in your handwired masterpiece throwing different values of all kinds of stuff in there?

I added a 3-way bright switch to mine. Absolutely terrific addition to an already great amp. Works great clean and overdriven.

Your power station can also add brightness via its tone switches and presence controls.

I like Tom's idea. Why not?

I like Tom's idea. Why not? It's an innocuous little mod that is easily reversed. You could even use test leads clipped to a little silver mica cap and find a value that you like.

There are a couple of options to adding a bright switch as a separate switch. You can change the volume pot to a push/pull pot and have it switch a cap in for brightness. Caps range from 100pF to 500pF depending on your taste. I’ve done this on one of my amp builds that is essentially a Marshall Plexi circuit. You could also just put a capacitor across the volume pot first and second lugs and make it permanent. That’s what Fender did on their bright channels. The first option doesn’t change your amps look and is easily reversible. This is the one I used. www.amplifiedparts.com/products/potentiometer-cts-audio-1-m-spst-push-pull-solder-lugThe amp I did it on is in my avatar.

While I don't have any issues with modifying an amp, I'd check out a few EQ or treble boost pedals first. A pedal would likely give you more flexibility than a bright switch when changing guitars, speakers or cabs. I'm sure there is one out there that would do what you want.

One pedal I really like is a Jacques Fuseblower. 3 TS808's in one box, one voiced for lows, one for mids, and one for highs. On my homemade 5C1 Champ clone, it did the job. (I also added one capacitor, per the advice of someone on the Weber forum - now defunct.) That amp employs a 6SJ7 pentode for a primary tube. I understand that pentode primary tubes have that issue. jacquespedals.com/shop/fuseblower/
