GK 1001 RB11 Vs Ampeg SVT 7 pro
My take (I've got both in my studio right now)
I absolutely love most aspects of the 7pro. Warm, loud, thick, did I say loud? Only problem I have with it is a lack of articulation in the mids- the five position selector definitely produces five different frequencies, but even cranking the mid control full on in all five different positions left me wanting more control and still not completely happy in live settings.
The 7 pro replaced my GB Streamliner 900 and got me half the way there with regards to the articulation I was looking for. I found the 900 to get lost live in almost all the applications I tried. Another great amp, and can totally see why people love it, I just couldn't cut through live (which bummed me out). When I first got the 7pro I was ecstatic because I was comparing it directly to the GB- once I gigged it about 80 times though I still wasn't 100% there.
Funny thing is that I think I was always comparing them both to my GK rig without realizing it. A long time ago I bought the GK1001 rb 2-10 combo for my little gigs- at the time it ended up being capable of playing almost all of my gigs so I gigged it hard (wore the speakers and box down by pushing it too hard). I don't remember ever being bummed on my tone or having a hard time cutting, getting a deep enough presence, or having any band members say anything other than "wow" about my playing or tone. When I moved on from it's format the first amp I bought was the GK fusion 550 (which I didn't care for and returned). I then bought a Mesa M9 (which I returned), then the streamliner (which I gave to my guitarist), then the 7pro (which I've gigged since). Never thought about another 1001 (moron).
Anyhow- I removed the 1001rb from the cab, bought rack ears, and now I'm back to the GK rig. I'll report back after a few months of gigs, but just from the rehearsals my tone is back to where I like it.
For me the 1001 has the ability to have a huge bottom end, while maintaining the bite and clarity that I need. It doesn't get too pillowy, doesn't get lost in the mix, and has a TON of flexibility. Plus it's loud, really loud.
Just my two cents, and I figured I'd throw this out there for others that are considering these two amps. I have no real brand allegiance, and have tried everything under the moon. Just reporting on my take and experience.
Wow, lack of mids?
I haven't played the 7 Pro, though I own a couple of 2 Pro, and AFAIK they use a similar preamp design. I have the opposite problem -- can't dial out enough mids. Of course, I'm using a highly mid-voiced cab. This makes me think if you can't get enough mids, then trying another cab and/or more EQ might help.
using both Berg HD 410 and HD212s. It's not so much "lack of mids", it's lack of articulation IN the mids. Brings me to the possibility that it the tone of the tube that I am not digging. At the end of the day I could very possibly be a player who prefers solid state amps (although I have never been left wanting for much of anything playing SVTs as backlines)...
I played a 1001 rb on a backline rental. I rally liked the tone BUT i had an issue..
While playing finger style then one passage had a few finger snaps..
Just picking the string up so it slapped against the finger board for an accent.
The 1001rb red LED came on for about 3 seconds while the amp cut the speaker out... Thank God i had a DI doing. that 3 seconds seemed like an eternity.. Is that normal for a 100rb to do.
I was running One 8 ohm cab.. pretty loud but not to teh point of speaker damage at all..
interesting. Never have had that issue. To clarify- you popped some strings (slap/pop style) and the amp went into protect mode? How hot was the pre amp (volume) knob?
yes exactly.. I dont remember the preamp setting.. maybe 12 oclock or so.. just guessing
funky. I've run my soooo hard and never had any kind of issue like that. I would guess other GK users have though.
I think the 1001RB is phenomenal, but I had the same problem as SVTB15. I was running a Turbo Rat directly into the amp, and had it set to where when I stepped on the distortion there would be a volume bump. Every time I had the distortion engaged for a while, it would do the cut out/red light protect mode thing. I had that happen with two different 1001RBs. Maybe I just got unlucky, and got two bad ones. But like, SVT said, those few moments where the sound cuts out feels like FOREVER!
Awesome powerful sounding heads, minus the cutting out issue I had.
It happened to me while i was on a gig in Paris France. I had a Backline rental of a 1001 rb on one GK115 cab.... I only had my Peterson Tuner inline..
The amp was only seeing an 8 ohm load on that cab.. I loved the sound but it freaked me out for a second when that happened..
Then when i got home i borrowed my friends 1001rb and tried it on my GB115.. and it did the same thing on an 8 ohm load..
Dont remember settings.. Gain would be maybe 12 oclock.. EQ fairly flat with maybe a slight upper mid cut... Master to as needed...
Playing finger style then doing a Pulling snap on the G string on an accent.. and Amp went to Redlight LED / Mute for about 3 seconds...
So im glad that I am not the only one this happened to.. whewwwww
Now, question is. Did this happen on OLDER units? If so, are new units updated so this doesn't happen.. ?
Id prefer that an amp LIMIT itself and pull back some when hit with a hard snap, than to totally cut out for a few seconds ...if thats what it was doing.
Sorry for the derail... The svt7 does look like a nice amp....
The series II does have a beefier power supply and cooling.
That 1001 is a standard..... I should try one out one day...
How do they compare volume wise to the SVT7 or Mesa M6
same amount of volume I would say, regardless of the watt ratings. They are both very loud.
Just my experience.
mine is a II as well and have never had this happen. Never even heard of it happening until now, good to know though for sure....
This is a new one on me....not saying it can't happen though, it obviously has.
A 1001 on a single 15 couldn't have been turned up all that much, eh? It would send the speaker flying across the stage. Tells me it shouldn't have been any sort of thermal protection type thing.
I dont remeber where my MASTER vol was set... Im sure it was loud. but not all that loud... DEF not enough to make the speaker freak out ... It was early on in the set so the amp was still fairly cool... and it didnt shut down as a TEMP related issue. That would stay shut down until the temp returns to normal..
It shut down for about 3 seconds max..
Anyway... I want to get one of these 1001 rb amps.. or maybe the fusion550... I just want to make sure its not going to freak out if i hit it hard for a second.
It is pretty easy to hang a single 15" with that amp when slapping/popping. That might be what was happening, when the voice coil was outside the protect circuit may have fired. Just spit-balling. I have not experienced this with a G-K but I have spent the most time with the 800RB and Fusion 550. I had a volume drop for less than a second once when I was running the 550 pretty hard, we were in the middle of a song and the guitarist summoned he over cause his Marshall was acting weird. When I dug in and it happened again I saw the power light on his Marshall really dim. Seems there was a bad supply circuit on the portable (trailer) stage.
^ that makes sense... Maybe i was hitting that 115 a little too hard.. I tend to do that at times.. ooops
My 1001 rb issue was on a couple of nice concert stages. with heavy quad box drops all around.. full Claire Bros PA.. There should not have been a current issue there.. although.. anything is possible
I need more info on the fusion 550 too.. I think there is a thread here.. somewhere
I believe it was Bass Gear Magazine issue 4 that had a in depth test, can't get a link to work though (on the Fusion 550).
