Read this and understand it before trying anything (my method is further down in this post):
http://www.bossgtcentral.com/modules.php?name=Forums&file=viewtopic&t=11871
As long as the "Loop" is set to on in the GT-8, your Amp's preamp will be in your gt-8's "Loop". Position the "Loop" in the desired position in the GT-8's effect chain.
Most users of the 4CM with the GT-8 have reported a slight loss of punch after sending through the GT-8's effects loop (I guess it's not that transparent). A few Marshall users on that GT-8 Forum have had a few more problems than others, I seem to have noticed.
Here is the front page:
http://www.bossgtcentral.com/modules.php?name=Forums
Make sure you check out the "GT8 Connections" Thread, before posting any questions, they will most likely have been answered.
A typical effect chain for the 4CM that I use is (along these lines):
Wah>OD>PRE>LOOP>NS>EQ>FX1>FX2>CHO>DEL>REV
NS - Noise Suppressor isn't normallly there for me (usually near start of chain) but the GT's Loop introduces some noise so put the NS here to get rid of it.
The "Effects Return" LEVEL is very important to get right. Read the tutorial thoroughly.
I used the tutorial as a guide, and went a bit further to level match the sounds by micing my cab and looking at an Input Level Meter in my recording software. I did the following with the amps Master Volume on 5 to check that the level matched at decent volumes.
MAKE SURE YOUR GT8'S EFFECT RETURN IS ON 24 (DEFAULT 100) IN CASE AS MENTIONED IN OTHER TUTORIAL IN CASE YOU HAVE A LINE LEVEL ON YOUR AMP (AND NOT AN INSTRUMENT LEVEL)
Step One:
Guitar>Amp Input - play your guitar and note the largest input volume
Guitar>Gt8 Input>GT8 Send>Amp Input - make a new patch with NO preamp or effects ON and set "Effect Send" Level to 100. Play guitar and note level (is it the same as with no GT-8? If yes good, if NO make sure "Patch Level" is on 100 (no other effects, EQ are on, etc...) and adjust GT-8 "Effect Send Level" until it matches (it should be close anyway, if not firstly make sure your "input level" is set correctly on the GT-8, mine is set at -3db for my EMG pickups for example)
Guitar>Gt8 Input>GT8 Output (left mono for example)>Amp Return
MAKE SURE "OUTPUT LEVEL KNOB" ON BACK OF GT8 IS ON MINIMUM AND ADJUST THIS UNTIL YOUR LEVEL MATCHES THE ORIGINAL GUITAR>AMP INPUT LEVEL You shouldn't need to adjust this again, I covered mine with some duct tape. This is slightly different than in the other tutorial, but makes more sense to me, but who am I.
Guitar>Gt8 Input>GT8 Send>Amp Input>Amp Send>GT8 Return>GT8 Output (left Mono for example)>Amp Return
MAKE SURE YOUR GT8'S EFFECT RETURN IS ON 24 (DEFAULT 100) IN CASE AS MENTIONED IN OTHER TUTORIAL IN CASE YOU HAVE A LINE LEVEL ON YOUR AMP (AND NOT AN INSTRUMENT LEVEL)
Play your guitar and note the level, if too low, raise the "Effect Loop Return" on the GT8. If your amp's Loop is Line Level it should be 100 (or slightly higher to allow for the loss from the GT8's loop). Don't go too much higher, you will hear it. It will introduce too much noise and mod effects will be muddy, etc...
As an example, I am using a Krank Revolution, I have read someone from Krank saying that their effects loops are not designed for individual pedals but for rack type units with Send/Returns due to the pedals having some sort of compounder thing or something that keeps the levels at guitar/instrument levels. This gave me the impression that I would need ot set the "Effect Return" Level low. I tried it and the level was far too low. I raised ti to 100 and was much closer. There is a slight loss of volume, but I thought it is better to be slightly under than over so not to boost the input to the poweramp. It does take away some of the crunch as well (ever so slightly but noticeable, and still useable).
I think that's about it. Once those levels have been set up, when you make new patches, just be careful not to introduce any clipping from the GT8 by using the Level meters in the GT8 and move through the effects chain to make sure you are keeping unity gain with each effect.
DISCLAIMER: THIS IS JUST MY ROUGH GUIDE, USE AT YOUR OWN RISK.![]()
You can now use your amps tone in your GT-8's loop when the "LOOP" is switched on, or turn the loop off and use the GT-8's preamps into your amps poweramp. The cool thing is that things like your wah, pickup simulator, OVERDRIVE (put that Tubescreamer on and boost the REAL Amps preamp), etc... is before your GT-8's preamp or your REAL amps preamp (if the loop is on and the gt8 preamp is off) and mod effects, delays are after the preamp where they should be, as you can see here:
Wah>OD>PRE>LOOP>NS>EQ>FX1>FX2>CHO>DEL>REV
where "LOOP" is your REAL Amp's preamp and "PRE" is the GT8's preamp.
Overall this 4CM is not perfect (due to the small losses and introduced noise - remember to have the noise suppressor after the LOOP), but is easy useable/tolerable with my amp at least, I hope it works for you, even though a few guys with Marshalls are having problems with it as I mentioned. Good luck.
Here is a quick clean sample I did the first day I got my Krank Rev. It is the Kranks clean channel (in the LOOP of the GT-8 ) with the GT-8's chorus and delay after it going back to the Krank's poweramp
Chain:
BC Rich EMG85 (Neck)>Boss GT-8>Krank Revolution>Mesa Trad 4X12>SM57>M-Audio Firewire Solo>Cakewalk Guitar Tracks. No post EQ, anything (raw recording) just volume boosted.
It was just a test recording one-track, one-take, bum notes and all.

Hope this post helps, I know its rough, but I'm in a bit of a hurry.

From the Tutorial on Bossgtcentral: (did you read it dude, it's the first couple of paragraphs![]()
)
-Depending on the brand and model used, THE MASTER VOLUME OF YOUR AMP CAN BE DISABLED WHEN YOU PLUG AN EXTERNAL PREAMP in it. Check it by plugging your axe in the GT and the GT output in the loop return of your amp: if the first riff played destroys your ears, maybe youll have to control the master level with the volume pedal of the GT
From memory this is part of the problem Marshall guys were having, sorry can't help you if this is the case.
-THE TONE STACK OF YOUR AMP CAN BE ACTIVE OR NOT WHEN YOU PLUG AN EXTERNAL DEVICE. Again, try it live, with the GT direct in the loop return: do your bass / mid / treble controls modify the tones from the GT? If its the case, choose one of these output options: JC 120/ small amp/ combo amp / stack amp. If your tone stack is disabled (no action from your pots), choose JC return or combo return / stack return / line-pa The output option wont modify the tone of your loop. But it is a key to obtain a good tone from the onboard preamps of the GT;
When I am using the GT8 as my pre-amp (Loof Off on GT-8) my amp controls do NOT work either. These controls are for the PRE-AMP and if you have the GT-8 Loop OFF, you will not hear a change in your tone since you are not using the real PRE-AMP. You have to set up the GT-8 as your pre-amp using IT'S Bass/Mid/Treble/Level just as if you were using your amps REAL pre-amp. With the GT-8 Loop ON your amp controls (pre-amp that is) should work as normal since you are using your amps REAL pre the controls should adjust its sound.
Again from the tutorial:
-Set the loop on NORMAL mode.
On the back of the JCM 2000, there aren't any loop level knobs, only a pushbutton loop level boost...I think it's 20db or so. I keep this pushed in when I have something in the loop. Is this good or bad or neither?
Again it would depend on what was in the Loop I guess. If you were using Pedals with "guitar-level" signal you would maybe use the boost to get it back up to a "Line Level" that your poweramp requires, maybe, I don't know for sure, I am not familiar with your amp. I would have NO BOOST when the GT8 is in the loop and first try the tutorial and my method as far as GT-8 Loop send/return levels and see what the result is.
Again, read the tutorials, most of your questions should be answered. I know, it's long and boring, blah, blah,:zombie: but every amp is different and YOU will have to fine tune it to best suit your needs and you need to understand how it works to make it work unfortunately.
Good luck.![]()
I used to have a DSL100 and got some really decent metal tones by sticking a GE-7 eq in the loop, cutting at 400Hz and 1,6 - 3,2 Khz, while boosting at 200Hz and 800Hz a bit.
I also boosted it sometimes with a Marshall Shredmaster (not exactly a boost pedal but it did a pretty good job) and got a much tighter sound out of it.
And again: Tone shift always OUT!

Glad things worked out for you.![]()
Unfortunately some of those GT-8 preamps can't handle the gain set above 30 before destroying themselves and your eardrums.uke:
As far as EQ, it's pretty patch dependant so I have any hard 'n fast rules to share unfortunately. Try some of the "Ez tones" for the EQ (press "EQ" button and then "Parameter Left Arrow" until "Quick EQ" is displayed and then use the Jog Wheel to scroll through different EQ presets such as "Fat Lead", "Mid Boost", etc...) until you get close to the desired sound and tweak to suit.
Are you using any of the software the guys wrote over at BossGTCentral? Mr Sleepy's was the first and I still use it to transfer to and from the GT-8 and there is a new one called GT-8 master which is very easy to use, especially for assigns (absolutely brilliant for a complex task to be simplified like this). GT8master doesn't up/download to gt8 so MrSleepys is used for this. You will need USB to Midi cables though for it to work. Some cables also require you to plug the "Midi In" plug of the cable to the "Midi Out" socket on the gt8 and vice versa, some do not. Apart from that its piss-easy to use/setup.
One other cool thing to try is putting the Wah after the Pre-amp (real or GT-8 pre-amp) in the effects chain. Check out some weird combinations, they're endless.
Good Luck.
