Hey all my other guitarist just got a Randall V2 head and he's having problems doing the 4 cable method with his Boss GT-6 processor. I found some info online below and messaged it to him:

Physical connections would be:
Guitar>GT-6 In
GT-6 Out > Amp Input
GT Loop Send> Amp Return
GT Loop Return> Amp Send

For starters, if you have a good amp and cab, switch off the amp and speaker sims in the GT-6.
The GT-6 has a manual stomp box mode so you turn effects on and off by stomping on a switch. Rather than a preset/ that turn on and off a series or chain of effects.. I would start with the stompbox mode when using the 4CM. So imagine you have 5 effects want in a chain. Wah>Overdrive> Boost> Delay>Reverb. In the GT-6 you can create the chain and assign where each effect goes, in front or in the loop. Of course, in this example I would put the Delay and reverb or any modulation effects in the loop.

He also downloaded the owner's manual to the gt-6 and thought he may be getting somewhere with the internal routing thing but now he's saying still bypasses everything on the front panel of the V2 but the volume. Not able to use amp distortion yet...
 
Here is how to hook up GT8 Try it with GT6 loop return goes to amp input that is why he is bypassing preamp.
The "4CM" (Four Cable Method):
Let's say you have an amp you love, you love the distortion out of it but you want to also utilize the GT8's preamp tones at times as well. There is a way to loop in the GT8 so that you maintain your FX chain order, can utilize you amps preamp tone and switch OFF you amps preamp tone and ON a GT8 Preamp. The basic idea is this: Guitar-->GT8 Input-->GT8 FX SEND-->Amps Main Input-->Amps FX Send-->GT8 FX Return--> Main GT8 OUT to Amps FX Return. This method 'isolates' your amps Preamp section to either be used or bypassed depending on wether the GT8's FX loop is ON/OFF. The idea is this: Guitar goes into the GT8 and through effects that belong before preamp distortion such as Wah, Compression, OD/Dist(stomperz) etc.. then gets routed to your Amps Preamp then back into the GT8 for effects that belog after distortion such as Chorus, Delay, Reverb etc... if your not sure about FX placement do a search for it or go to Amptone.com. (good info there). The other beauty behind the 4CM is when the loop is off the GT8 has a direct shot to your Power Amp secton of your amp. This is where you would use a GT8 preamp in place of your amps preamp. The tone controls of your amp get bypassed too so it is a fairly transparent sound. Level matching is vital here. A/B your amps preamp with one of the GT8's (Loop OFF) to get the two to be matched. When bypassed you amps volume control (on most amps) is also bypassed so the levels become important to watch.

If you have a Series/Parallel Loop or both or just Series it is important that you choose Series. You want the whole signal coming thru the GT8. A parallel loop allows you to mix in varying amounts from the FX Loop.. Due to the small latency of the GT8's processing you will get an out of phase sound (*much the same as described in the GT8 Preamp Dual Mono mode section, same principal). If you have an FX Level knob then it is a Parallel Loop and you want to set it to full on (100% up) to avoid any phasing problems.

I don't know what else I could cover in this 'brief' explaination, but hopefuly it will help anyone whom is new to the GT8 world and is struggeling a bit. I'm sure I left a bunch of things out, but maybe I can make a revision of this in the near future. Also, this is generally what I do and it works for me, it is not gospel nor complete..it is merly a guide on how to get a good basic fundamental tone. There are alot of how's and why's left out along with effect placement...but there is a huge resource on the net for that as well.

Thanks a bunch!! :thumbsup: I'm waiting to hear from him after he tries this
 
Well had practice and my other guitarist brought the Randall V2 over to use and MAN IS IT LOUD!!! He just ordered all new preamp tubes from Valve Queen as well tonight. It was cutting thru like a knife! My Tremoverb with Boss SD-1 for a Boost was almost getting buried in the mix?!
 
Yes they are 400 watts solid state and a tube or solid state preamp. Have not seen one around for awhile

Actually pretty sure it has both a solid state preamp and a tube preamp, not sure though?
 
Hey Guys, i'm using the GT8 and an EVH 5150 with 4 cable method. Is there any way i can make the GT8 patch changes seamless? I don't use the amp models and i've level matched all the FX and loop levels pretty well, GT is not running hot at all anywhere.. The presets i've made are all copies of the basic patch, just FX settings (DELAYS, CHORUS, WAH etc have different tweaks). Its sounding great apart from the non-seamless changes!!!

Rexx.
