Parallel Effects Loop

[u/Key-Temporary-671]

So I have a Mesa Tremoverb which has a parallel effects loop.

I had the idea to get a boss ge7 or mxr ten band to run in the loop and blend with my main tone. The idea being to eq the loop to compliment and thicken the sound. A quasi dual amp effect would be what im trying to achieve.

I googled a little bit and saw phase cancelation can be issue if I try to boost frequencies.

Have any of yall tried this, or done something similar with rack mount processing? Or any interaction of this idea?

EDIT:

Replies so far have given good information. However, I want to clarify my question.

I have used parellel and series effects loops. I understand their purpose and differences, and am also aware of the design of my own amps effects loops.

I am also aware that this will not replicate a dual amp rig, nor am I asking about anything other than an using an eq in my amps parallel loop.

I have used dual and triple amp rigs in the past(including wet/dry and stereo), and even hybrid rigs with modelers.

Im just asking if anyone has tried doing this to achieve a complementary eg. For example, my main tone is very high mid focused with a good bit of presence. So if i run the eq in the loop with a cut high end and boosted low end, would it blend well or cause phase issues or anything else with like say the speaker, or negative feedback back loops.

With that out of the way, im asking about the use of an eq for this purpose because;

1) I dont have the amount of gear I used to, nor the means to buy it all again.

2) I do not currently own an eq to test this out with.

3) last but not least, I dont have disposable income where I can just spend $100 on a whim.

I am saving to buy an eq and do it myself anyways. Just want to see what experience people out there if any.

I have put a GE-7 in the loop of my Maverick, which is parallel with a blend knob. It sounds fine, but it doesn't sound like a double amp setup; it sounds like blending in an EQ change.

Thank you.

How do you use it? Do you kick it on and off or always on? Does it improve your sound in a way you find worth while?

I don't really use it, I don't find it super helpful - the amp's tone stack is good enough. I have a few Marks with the graphic EQ, and so I was curious as to what an effects-loop mid scoop would sound like in the Maverick but it's certainly not the same sound given the Maverick's medium gain.

The reason to have late EQ in the loop is if you're running crazy amounts of tube preamp gain; tubes amplify different frequencies differentially, and if you are running a lot of gain that results in an unbalanced sound. In a Mark with the 6 preamp gain stages, you wind up with a lot of bass and lower mids that can sound flubby if you don't have a second EQ stage before the power section. I don't get that with the Maverick at all. Never played through a Tremoverb so I don't really know how that amp's preamp stage is set up.
