ISP decimator pro rack vs stereo version?

[VESmedic]

I found a decimator pro rack (not the "G") and I can't tell the difference between this one and the stereo version? The pro rack has 2 channels, 2 knobs, and 2 sets of input/outputs on the back, just like the stereo model, so whats the difference?

The stereo has an extra set of outputs on the back. Not necessary for most setups.

Okay...so the "regular" version has 2 sets of ins and outs...aka 2 channels....will this be sufficient to run 2 amps? One set of ins and outs for each effects loop..?

brother, that is EXACTLY my plan for the loops of the ultra lead and the herbert. just got one off this forum last week for that purpose (not the stereo one). now i just need a 2 head flight case (like yours) with 8 spaces of rack gear room.

by the way, you gotta try the VHT UL with an isp sub, and the herbert though the warhead cabs with 2x15's. unreal. just need to make the two heads dead quiet now.

told you we were kindred spirits.

I had one of the regular rack versions but couldn't find how it was better than the pedal. It's larger, heavier, and way more expensive for one more knob to adjust. I kept switching back and forth and eventually sold both the rack and G-string pedal, and used a regular ISP on the front end and made my rig simpler. Maybe someone can explain the advantages and price of the rack version to me? maybe it just was necessary in my particular rig.

some heads do not like pedals in the loop. the VHT stuff specifically. needs to be a +4 signal (rack stuff) instead of the -10 (pedals).

we are trying to get rid of the hiss from the preamp section of these heads. (note, the decimator pedal works fine in the loop of the herbert)

the randall rm-100 was also bitchy with a pedal in the loop. i bought that ebtech thing to solve that problem, then sold the randall to score the herbert.

The main advantage of the ProRackG as oppossed to the Decimator pedal as it gates both before the input and after the preamp. You have to run into the first input/output of the ProRackG before the input of your amp/preamp. Then you come out of your preamp out/fx loop send into the second input of the ProRackG. Then out of the ProRackG to your fx processor input, fx loop return, amp input etc.
For those of you wanting to use the ProRackG for multiple amps/preamps, you're gonna need the stereo version. The stereo version has an extra input/output added that you run into prior to the input of your amps/preamps. You'll need a splitter or mixer to send a signal to both amps/preamps inputs.
Edit** Also, make sure that if you are going to run multiple amps/preamps you get the Stereo version with the 3 ground lift buttons on the back. Without them you are almost guarenteed to run into grounding noise issues.

Thanks for all the good info guys! Ok I bought the regular isp rackmount, I think it will be plenty for my needs, plus I got a used one for 200 bucks used out the door! okay quick question about the decimator rackmount and effects loops:

My Ultralead can be either paralell or series at the push of a button: how do I want it set with the decimator? Same thing with the herbert, I can plug it into the paralell or series loop. Also, if I had let's say a rackmount going into that particular loop as well, how would my signal chain go? I'm guessing: decimator input > fx processor input> amp send, decimator out>fx processor out>amp return? Just a guess on my part...thanks guys!

good questions, me wanna know too. i do know for sure you run any noise suppression is series, not parallel.

i got the pro g, but not the stereo one. but i dont plan to run into it with my guitar signal at all.

my signal chain will be guitar-boss ns2 gate- amp splitter- front of the two heads.

each amp will get a channel of the decimator pro g in it's series effects loop to get rid of the amp hiss. the threshold of the isp will be triggered by my boss unit out front clamping shut (or my kill switch), thus silencing the preamp hiss. (i have been running two gates like this since the decimators came out. the boss up front and the decimator pedal in the loop. i have never tried the g-string or any of the ones that track your guitar signal in an x-pattern for the loop)

wish me luck. wont be home for another week or so, so you might beat me to the punchline brother. if it turns out i need the stereo version, i will just use the one i have for the VHT, and run one of my decimator pedals though the herberts loop.

edit....always put your gates in front of any time based effects (delay,reverb,etc). if you have the gate after the effects, it will choke off your verb or delay repeats.

Won't work. The ProRackG needs your guitar input signal in its first channel. It doesn't work like a conventional noisegate. You'll need the stereo version for what you are wanting to accomplish. See my previous post and yes, I currently own two of the stereo versions so I'm very familiar with these units.

Always in series with a noisegate. Same as with a compressor, tremolo etc.
