I couldn't stop myself....the deal was WAY too good. it included the control 2 pedal and free shipping for less than the cost of a used GSP1101. i missed a few tones that i had, especially the weird atmospheric stuff, plus the ability to load IR's (which i never did back when i had one before).

i'll post some comparisons once i get it in and all setup. i'm sure the eleven rack will feel better thanks to the true-Z input, but having the harmonizer from the GSP1101 will be cool.

stay tuned....

lol damn GAS !!! im very interested in the results loading irs inthe gsp,cause i heard they have to be badly truncated to fit the gsp,keep us informed singtall !

hey Singtall, let me know how you like it. I was on the fence about adding one to the arsenal.

It will be interesting to see how you feel after getting back into the unit. I still have my RP500, and in general I find the 11R more enjoyable to play stand-alone. Sounds more real, more inspiring, all that stuff.
However, recorded with both in a mix (say 11R left, RP500 right, similar tone/gain) the RP seems to dominate and have more balls for lack of a better term. I think it's just a little more compressed and that tends to make it stay out in front better. I'm talking about lower gain stuff similar to REM or southern rock type stuff as well. Just my opinion.
And you can get real nasty tones that I don't think are achievable with the 11R when getting creative with some of the pedal models (gonkulator, etc). Those are fun to play with too.

i spoke to a guy that said i can load the Ownhammer presets directly into the gsp1101 without any modification to the IR, which is great news because you used to have to remove any silence to make it sound right. i don't remember Ownhammer IR's having much if any silence in the front of the Wav file, so i should be good to go.

my memory of the gsp1101 was that it was far more compressed and 2 dimensional when compared to the eleven rack.....but i was using a LOT more gain back then. people that tried my presets actually complained that i needed to back off on the distortion. lol.

I picked one up myself a few months ago. Got it used with the Control 2, a MosValve MV-962 and a 4U Gator rack case shipped for less than a new GSP. Right now I am using just the GSP with my recently acquired Fender Prosonic head and its fantastic. I can flip seamlessly between models and the Prosonic preamp, and I can add tremolo and a noise gate to my physical amp, something the 11R could never do.

The GSP is the clear winner for integrating into a live tube amp rig, but the 11R models are a clear step up in quality

I believe Vinnie Moore used some of those weird atmospheric sounds for faking synths with his guitar on Defying Gravity. I've heard some cool Van Halen covers and guitar instrumentals with it too, very 80s sounding but yeah kinda compressed 2D sounding but not necessarily in a bad way, but always has that color to it and not as dynamic as 11R/Axe Fx. I heard a clip not long ago with some good IRs that made me want to get one.

https://www.youtube.com/watch?v=cch5L1ApERo here it is a quick comparsion video between gsp stock and ir

heres a good discussion about the gsp ir truncation to 128/256 point vs the 512 point of the 11r (it seems) vs the 1028/2056 of the axe.
you have to read it all unfortunately...

the IR length effects the low end especially. but since i end up cutting muddy bottom end out of IR's (even on the axe-fx II) it appears that the IR length may not be too big a factor to me.

if you listen to the video's sound, you will hear more beef to the Redwirez IR. i think that's a good thing. more fullness is good. i have a couple Ownhammer IR's that are fairly neutral that get loaded up first thing just to test and see what the truncation will do to the tone.

i think that the best comparison will come when i load an IR in the gsp1101, then a/b it against the same IR loaded into the Epsi.
