OD2 to OD1

Post by Bailz » Sun Dec 09, 2018 1:30 pm

So, my understanding is that on the JVM2 series the Overdrive channel is roughly equal to OD2 on the 410, which has the mid frequencies shifted slightly to make for a more modern sound.

Should it be possible to do the OD2 to OD1"mod" using a 10 band EQ? Plan would be to cut some of the lower mids and push the higher ones.

Which frequencies are we talking?

Yes - but if you put it in front of the amp, or in the loop (better) - it will affect ALL your channels not just the OD channel. This may or may not be a good thing (depending on your outlook!) I am a big fan of having EQ in the loop....

Not necessarily. He could turn the loop off on the other channel.

That's true - I hadn't thought of that (mainly because I leave my loop on all the time!) - but yes, good point!

I think that's what most people do - leave the loop on all channels all the time. Then it's true the EQ in the loop will affect all channels and modes.

In the rare event that I actually change channels on the JVM on the fly, I usually keep my rhythm channel dry and my lead channel loop engaged with a little delay in the loop.

Thanks guys.

Yeah, I don't swap channels that much. Most often on the OD. It's a Boss GE-7 that I use so that can also be switched off and on as necessary.

Any one got the particular frequencies that need boosted/cut?

Thanks,

I don't know the exact frequencies, but I figure it's mostly between 700 - 1200Hz (boost). If I were you I would just boost mid frequencies according to taste.

I think it's much easier to just mod the channel. Once it's done that's it, you have the tone you want, and not have to worry about dicking around with another pedal and power for it.

Yeah, I know what you mean. Looking into the mod now.

I noticed in another thread that 100V capacitors are recommended, but should these be AC or DC ones?

I had been using an MXR 10-band EQ with my 215C using the settings recommended in the forum a few years ago based on Santiago's "conversion" curve (still there if you search), pretty close approximation of OD1. But, I recently picked up a JHS Haunting Mids pedal and I'm actually happier with the results of that one.

I don't really want the extra bass of OD1, I like the tight bottom-end of OD2, I just wanted those more classic-sounding mids, the JHS does that nicely. Also, contrary to what you would think, per Santiago's EQ curve the most boost is needed in the lower mids, about 2.25db from 400hz to 500hz. I use the JHS to boost 400hz a little and it gives me the OD1 mids that I like but keeps the other aspects of OD2 that I like.
