JMP1 and G-Major

Hi,

This is my first post, I've just  signed up  ! )

I run my G-Major in the FX loop of my JMP-1, I found it sounded best in the loop (which I can then also switch on and off per patch and kept it out of the signal path) rather than have it after the JMP-1 where as everything goes through it. Also helps if it freezes (though mines only done that twice in two years) as I can change to a patch with the G-Major out of the signal path and no-one will know !

All this goes into a Mesa Boogie 50/50 into a Marshall x12 cab. I prefer the sound of the 6L6GC tubes with the JMP-1. How do you find the EL84 ?

Hope this helps.

What do you mean with "also helps if it freezes"?
I have this issue with my G-Major (it freezes). I connected it how was suggested in the manual (JMP1's outputs to the g-major's inputs, and g-major's outputs to power amp's inputs).
Do you think if I connect the unit in the FX loop, it won't freeze anymore?
It sounds strange, but I'll try.

So... you connected the JMP1's send to the g-major's LEFT input (the right input remains empty), right? and the g-major's outputs to the JMP1's returns.

For some reason whenever I hook up my g-major into the fx loop of the jmp-1 I notice a significant loss of gain/volume. Note: even if I set in and out levels to max on the g-major, there's still less volume than the jmp-1 dry (fx bypassed). I'm also using balanced cables that are recommended by tc electronic.
Can anybody help me with that?

I connect these as recommended by TC...sounds amazing!
Key is to make the output on the JMP1 +4db and set the level to "pro".

I think the G Major manual suggests that because the loop on the JMP1 is parallel and TC recommends using the G Major in series.  If it's working for you though, it's all good.  I've had some issues using the G Major in parallel loops in the past myself.  Again if it's working for you and you're happy with it I wouldn't change anything.

Parallel loops and digital FX are not a good match.
Killdry, when available, is a treatment for the phase alignment problems created by the combination of parallel loops and digital FX. But like most treatments, it has side effects. Preventing phase alignment problems by NOT using parallel loops is much better.

Side effects?
As stated above - while fixing the wet/dry mix is fine for a delay or reverb, modulation FX require much more flexibility. If you turn on KillDry and use the Wet/Dry mix of the parallel loop, you LOSE the ability to dynamically control the wet/dry mix for post-gain modulation FX (unless you want to walk back and forth to your amp between songs and adjust the mix manually - of course ;-).

This can make those FX sound anywhere from anemic to over-prominent, depending on the application. It is far better to mix the dry signal and wet signal WITHIN the digital FX, since you can control the ratios (and go to a TRUE 100% wet when desired) on a patch-by-patch basis.

Consider things this way:
1) There is no good reason for a manufacturer to put a loop in their preamp product EXCEPT if the manufacturer wants to provide a parallel loop. The connection between the preamp and power amp IS a serial loop already. No need for extra circuitry or anything else.
2) Parallel loops were designed to compensate for old-style stomp boxes that had little-to-no dry mix.
3) Reason 2 above for the existence of a parallel loop is INVALID for modern digital FX including ALL of TCs guitar products. These products have an internal path and mix for the dry signal.
4) Digital FX have phasing issues in parallel loops.

You can see from the above that there are few good reasons for putting an FX processor in the FX loop of a stand-alone preamp, and there are VERY good reasons not to.

I have posted this question on the G-System threads because loopers and JMP-1's were mentioned, but I should really post it here in this one.
I currently have my G-Major inbetween my Marshall JMP-1 and Marshall power amp as the TC manual suggests, but I now need to put my Boss RC20xl loop station into this configuration. (I recomended loop stations they're awesome for practice, jamming, songwiting, and solo performances!)
Does this mean I have to remove the G-major and put it into the JMP-1's effect loop followed by the loop station?
If I leave the G-Major where it is and only put the Boss into the effect loop I think it will alter the loop station evertime I switch patches on it (because any OD, Dist, or effect after the loop station causes this.
...or anyone else own rack gear and a loopstation that could help with setups?

Thanks

hi all

any suggestions welcome

what's the best way to connect the following:

korg dtr 2000
marshall jmp-1
tc electronics g force or g major (i both at different times)
bbe sonic maximiser 482
marshall el84 20 20 OR a marshall jmp superlead mkII (roughly c.1979)

i also use  a behringer midi controller that you'd need a degree in astrophysics to understand. so i say 'use' in the loosest possible terms.

any ideas surrounding the use of fx loops and what to route to what?? the sound i'm getting is ok but it could be better. normally i run them in series.

Hi Deejill. You should search the forum. There are alot of post regarding that question. Try to ask someone in a musicstore.

I have just tried like you, i think it is very very nice, it is really pro. I am very happy because we have the same ideas. Everyone can try this, it is amazing !!!
