ISP Decimator G-string

[Beruska]

Hallo, I would like to ask if anyone has an experience with this noise reduction pedal.
I have read that the G-string tracks the direct guitar signal (put directly after guitar) and then finally removes all the hum being inserted into the amps series effect loop. So far it seems to be clear to me. I use several OD/distortion devices in front of the amp, so my main question is: if I place them after the ISP in the front end chain, will it remove also all the noise from the pedals without affecting the sustain? Or with another words - if I once set the threshold for optimum sustain for the clean sound and then switch my od/dist on, will the ISP still remove all the noise and hum without adjusting the threshold higher?
Please help me someone
Unfortunatelly here in Czech I do not have the oportunity to test it myself (we do not have ISP dealer) , and as far as it is fairly expensive, I do not want to make a mistake.

I would be very thankfull for an advice.

I have one of the first ones. Here's how I set it up:

Guitar > G-string > Tuner > TS808 > Amp > FX Loop Send > G-string > (EQ & Time Based FX) > FX Loop Return.

It only removes the hum and hiss when you're not playing. If set right you'll still have controllable feedback and no loss of sustain. It doesn't color tone. So if you do palm mutes with a long pause in between playing sections, the gate will slam shut when you go to silence. It needs to use the FX loop so it can remove the noise (hiss) from the preamp as well as overdrive and distortion pedals

I NEEDED it when I had the Marshall JVM. It's still useful with the other amps since I do have very little but annoying line hum.

Thank you very much, Julia343, your setup is very similar to the one I want to try - I was thinking like this:
Guitar > G-string > Keeley compressor > Sparkle Drive > RAT > amp...... FX send > G-string > delay&reverb > FX return.
If it works for you, I think I am going to give it a try.
Thank you and greetings from Czech.

I use the older Decimator pedal and I have it last on my Pedalboard but get most of my dirt from my amp. I set the Threshold so it cuts off when I turn the volume all of the way down. It is dead quiet this way and I still can roll my volume low to clean up my amp without affecting sustain or cutting anything off to early.

They work great!

It doesn't "remove" hum it's a noise gate, it shuts the signal off when you're not playing.

Just want to highlight this....I bought one hoping it would reduce noise and single coil buzz while playing, but it only operates when not playing. Does exactly what it is supposed to do, and does it very well, even though it did not work out for my application.

Thank you all for your suggestions - I have already ordered the G-string and hope it is going to work well. I have used the EHX Hum Debugger in the past, as it removed the hum all the time, not only during breaks like an usual gate, but I really could not stand the way EXH destroyed the tone and added some unwanted side effect to the game, e.g. some unnatural decay and overall "inside-the-brass-can" feeling. EHX also did not cure the noise from pedals.
After trying the G-string I´ll be back and post some experience.

Hallo, I am back after a while - just got ISP Decimator G-string few days ago. Works great - "decimates" all the noise and hum without sustain loss and tone coloring/sucking. Listened carefully to the very end of decaying tone I must say the way the gate closes is very smooth and musical. IMO it does a great job.

Cool.

I read that the G-String's advantage over the basic Decimator is that it tracks the clean guitar sound (less noise than after your pedals) via the effects loop.

My setup includes a pedal board with a buffer, compressor, overdrive, tuner into input of amp, and a delay pedal in the effects loop. I have some questions about where to place the G-String, and if the basic Decimator would be adequate.

From the text description on isp's website (below) I presume the blue "output" wire would go to the beginning of my pedal board signal chain, with the pedal board's output going to the amp. Can I route the G-String's red "send" signal into my delay pedal input, and the delay pedal's output into my amp's effects loop return? NOTE: I do not want the G-String to truncate reverb or echo tails, so I need to know where to place it if I'm using a reverb or echo pedal.

For my set up, does the G-String offer a significant advantage over the basic Decimator? I don't usually have much of a noise issue unless I'm using single coil pickups, and wonder if placing the basic Decimator at the front of my pedal board's signal path will suffice.

Per the isptechnologies.com web site:
As can be seen in the diagram, the G String noise reduction pedal has an input to connect a guitar directly and a buffered output signal to feed the front of a guitar rig directly while providing a separate audio channel of Decimator that can be inserted in the signal chain of any guitar rig. You can insert any other pedals between the output of the Decimator G String and the input of your guitar amplifier. This allows the Decimator G String pedal to remove any level of noise you may have even with overdrive pedals at the front end of the amp.

I would get the G-string so that, if you ever were to use it with a multi-channel amp (with varying degrees of gain), you could set it and leave it.

However, if money is tight, you want to keep the cables to a minimum, set your amp clean and if there is not too much delay or efx loop hiss...you might get away with the base-level Decimator.

Remember: The basic Decimator is a gate...it may work best cutting-off your guitar input signal by being placed either before or after your primary noise makers (ODs), but always before any delay and reverb effects. If you use heavy distortion, you could not place it after the distortion and expect a natural roll-off when you turn the distortion off (you would have to readjust the Decimator threshold setting); placing the basic Decimator before your effects would allow for just one setting, but you may hear some background hiss equivalent to what you would experience now with your guitar's volume off and your distortion pedal on. With the G-String, a simple recommendation would be to place all of your non-time-based effects on the blue...and your post distortion time-based effects on the red.
