Re: Feedback question...
are you talking nice controlled feedback, or uncontrolled squealing?

Re: Feedback question...
I know this isn't what you want to hear but you need to either turn down the volume or the gain. Jimi Hendrix did some awesome things with feedback but he played insanely loud. In your small room just try to keep the volume down a bit & you can get some pretty cool feedback going. I can actually pull a harmonic overtone out of my amp at will. It Is a graet amp & a graet guitar does help too. You need some volume to make this happen but you don't have to blow the windows (or your ear drums ) to get it done!

Re: Feedback question...
Squealing feedback, is usually coming from a microphonics issues. Once you have some little metallic parts free to vibrate and, those vibrations can be catch up by anything on your signal path, you've got feedback.
There are several spots to look at:
Pickups:
Have a base plate? firmly glue that base plate to the bottom of the pickup.
Adjustment screws have a spring? substitute those with rubber tube.
Are pickup wax potted? pot them or redo the potting.
Guitar cords:
Has your cable a copper strand core?. Try using a solid core cable or, get some cable with protected strands (as the Evidence Audio The Forte).
It's your cable 100% shielded?.
Jacks:
All around. A loose jack can do really weird things and, you have those everywhere.
Amp:
Maybe your tubes, and very specially V1 are microphonics.
Try to swap first V1 with a HIGHGRADE LOW MICROPHONICS tube.
If V2 is also part of the cascade gain, try also a low microphonics tube.
And then, the easier way to get rid of this issue: try an ISP Decimator G-String, the only Noise Gate that I know does the job flawless, don't expend the money on anything else.
Want a demo of how the G-String works?.

Try Survey Monkey - very useful for getting controlled feedback...

Re: Feedback question...
The G String does not control feedback. Yes, feedback eliminators are just graphic EQs that sense where the feedback is and then automatically pull down the corresponding frequency slider. They are sonically pretty obtrusive but important for vocalists especially the wireless type who frequently runs around the stage (gets dangerously close to the sidefills and or likes to hang around close to the monitor) and whatnot.
They are usually used on the whole FOH mix and on individual mic channels.
High gain guitar usually feedbacks at several different frequencies and is very hard to control.
But... if the room you play in is contributing to the feedback with it's particular "profile" you can usually eliminate the feedback with a simple graphic EQ because the feedback is occurring in the same frequency band(s) due to the shape, materials or items in the room.

Re: Feedback question...
I am sorry but, if memory doesn't fail, what the G-String uses to get rid of the noise is a downward compressor, under its threshold level and, not some kind of EQ notch filter.
And, BY THE WAY, DID YOU WATCHED THE VIDEO ????.
I am running 1 compressor, 2 overdrives, 2 distortions and 1 fuzz at same time, and everything is under control.
I don't mind what do you think the G-String does and, I even don't mind how the G-String does it but, IT REALLY WORKS!.
An image (and a sound) worths more than a word so the only reason I can imagine you are negating the evident is that you didn't watched the video. What it first, please, then comment.

Re: Feedback question...
I ran ALL pedals IN FRONT the amp. Nothing was on the FX loop.
What I did is:
Guitar -> GUITAR IN (G-String)
GUITAR OUT -> chain of pedals
last pedal -> DEC IN
DEC OUT -> Delay (or other time effects)
Delay -> Amp.
I also included the regular Decimator as the last pedal (before DEC IN), since this is the way the regular Decimator should be used, just for a clear comparision about, how difficult is to control the feedback with the regular decimator and how well does it the G-String version.

Re: Feedback question...
First off, I own an ISP G String. I never said it used graphic EQ to remove feedback because IT IS NOT a feedback eliminator.
I have used feedback eliminators before... they all are graphic EQ units.
Your video is over 17 minutes and it's in Spanish... I don't have 17 minutes to learn about a pedal I already own. I fast forwarded to hear your playing though. Nice stuff man.
Your ISP Decimator controls your feedback because your feedback is from running gobs and gobs of gain. Feedback can come from a variety of reasons and most feedback eliminators are for use with microphones and not guitars. It's a stage feedback sort of solution.
If the guitar setup's feedback cannot be controlled by simply putting your hand on the strings, then an ISP Decimator would probably work. Interesting suggestion Hermetico.
Good graphic EQs cost just as much as an ISP Decimator, so I think it might be a good idea. Plus, if the ISP Decimator doesn't work to remove feedback, they retain their value on the used market and can be sold quite easily.
