Warming up JVM 210 OD channel without mods?

So will try and keep the rambling to a minimum (though no promises lol). I bought a Jvm 210 about 2 months ago, after really enjoying my friends 410, but forgoing the 410 because in reality I felt I didn’t need 12 channels (only dwelled on a handful of modes on his)-confirming after messing around with mine, only seriously enjoying/using 3 of the modes (running through a 2x12 cab with V30’s). There is a part of me now that does feel maybe I should have just said screw it and opted for the 410 (considering the time it still took me to dial in the 210 anyway :facepalm:), seeing that I would’ve liked a little more classic warm high gain, which seems (after quite a bit of reading) to exist as the OD1 amber on the 410 (which the 210 apparently does not have-has the OD2 of the 410). Was not initially aware there was that much tonal variation across the JVM’s. I do use less metal type guitars (Gibson guitars loaded with PAF style pickups), so the tones I have been getting from the 210 OD channel have been quite awesome and satisfactory for a somewhat less dry metal, and more classic sound-especially in the amber mode (when it comes to very filling crushing rock tones, keeping the gain lower and adjusting guitar volume helps), though there is still a slight modern scooped tonal dna that runs through that channel (like most of you probably already read at this point, OD2 seems to have a different/lower mid frequency to OD1-not traditionally Marshall). Not horrible of course, just a little different. Short of the mods people have been performing for what seems to go back over the better part of a decade at this point, is there anything I can do (externally) to warm up the 210 OD to reflect more like 410 OD1 when I want it to, like adding a parametric or graphic eq? Any input would be appreciated.

:welcome: to the forum.
I don't have a JVM so I can't speak to getting the tone you're after.
But I'll say that adding an EQ in the loop on my amps (that have a loop) can change the tones drastically.
I'm also a proponent of coloring the tone of a clean amp with some pedals in the front end.
I love cranked native Marshall overdriven tube tones when the amp & speakers are being pushed, but I also get great pedal tones at TV volumes.

Getting OD2 to sound like OD1 is going to require manipulating the tone going into the front of the amp as well as in the loop.

Or you change out two caps and one resistor, but I get that not everyone can just grab a screwdriver, pliers and a soldering iron.

I would try an eq pedal in the loop as @fitz288 suggested, it’s a great way to shape the tone of an amp. I would try that first before doing any mods,… just my opinion.

And welcome to the Marshall Forum! :cheers:

What year is your Custom? Hard to tell the color, it’s gotta he either black or wine red? :cool:

Thanks, happy to be here :D:woot:(appreciate the input). it’s a 2020 in black (luckily wasn’t a lemon lol, was also nice they brought the ebony boards back and ditched the Richlite).

Any specific eq pedal that would be a good fit/appropriate? Seems like the MXR 10 band is quite popular (or the more basic 6 band if I don’t need all of the functionality).

I have the Boss GE-7. It does the job but wouldn’t recommend it but the Q of each band seems a little high, and it’s noisy, but that’s not really an issue with it in the loop. I would do the 10-band MXR by default.

If I were to buy a new analog EQ it would be a Tech 21 Q Strip. It’s your best chance in getting OD2 to sound like OD1.

The serious issue being overlooked is the voicing before the gain stages. There is a big difference in the bass response which I don’t think any pedal is going to be able to address and it 100% cannot be done in the loop. OD1 allows more low end to drive the channel but it’s still tight. You’d need a serious scalpel in front of the amp to reclaim it. OD1 isn’t as bright either but that’s not as big an issue.

All that aside, when you find something you like it doesn’t matter how you got there.

Great post, the Q Strip is one of the very few remaining parametric EQs on the market. The Empress ParaEQ is sadly gone. I am curious if anyone have tried the Two Stroke from Orange, a cheaper alternative:

Just ordered the MXR 10 band. Being a novice when it comes to external eq’s (didn’t want to embarrass myself asking stupid questions lol), in relation to reading the attached eq graph (following option 2 running the pedal in the serial loop), how would I properly set it on the MXR (approximately)? Do I keep the lowest and highest frequency sections on the pedal at zero (just what I’ve gotten from what I’ve read), and focus on the 100hz-4Kh range? Also, do I have to set the amps eq in a specific way when using the pedal (all at noon, or does it not really matter)?

just picked up the Two Stroke last week and so far I'm loving it! great range of frequencies you can tweak with a bonus clean boost as well. it's my first parametric EQ and IMHO much more useful than a graphic pedal. You do need to spend a few moments dialing in the tone since you are using your ears not sliders to determine what sounds good. you can't set a Q value but the curve seems pretty tight to me...I've got my eye on the Orange Kongpressor now!

I agree an EQ in the loop is probably your best option (after mods, which I understand you do not want to do...) I do not personally recommend the Boss GE7 because the bands are quite wide, and it is difficult to get the required shaping without compromising other frequencies, and also because it is quite noisy! (less of an issue with an EQ in the loop, compared to in front, I know....) The MXR10 EQ is a much better option in my experience...

You should have gone for the JVM410! The fact that you may not have used all 12 modes is irrelevant! They are not like food in your fridge - they won't "go off" if you don't use them! I use no more than 5 or 6 modes on my JVM, but each one does exactly what I want without compromises....

Another big issue with the JVM2** series is that the clean channel is common with the Crunch channel. This means that if you set the gain high for your crunch sound, Clean green is about 10 times louder, as it does not have a volume control!...Also the clean channel EQ is shared with the Crunch channel.....I use a JVM205C for smaller venues. I have modded it to get around these compromises, and it took quite a bit of tweaking to be able to behave in a way similar to the JVM410....

Try to map the sliders on your EQ on the diagram: print the diagram and draw a vertical line for each of the sliders where the slider frequency matches the X-axis frequency. Adjust the sliders to match the intersections on the vertical lines with the EQ curve.

One thing to keep in mind is moving the sliders up also increases noise.
