SVT-VR: The Definitive Thread

I tried out the VR this weekend through a 610. It sounded really nice! It had an edgy clean tone with a p bass. Almost growly. I was wondering a bit about the volume level though. The guys in the store were cool enough to let me turn it up a good bit. Got up to almost 2 o'clock on the volume dial and it wasnt "thunderous" loud like I expected. It remained clean and uncompressed. Very nice amp though.

Does anyone know if all the tube stages in the 70s version can be duplicated with only 12AX7 and 12AU7s?
 
I guess I should have been more specific - I was wondering specifically about the driver and phase invert stages of the original. I thought something other than 12DW7 was used there. The VR has 4 12AX7 and 4 12AU7 tubes. In addition to 6 6550s of course.

I was tempted to get an SVP-CL, but, meh, i like SVT-II too much, how similar are we talking sound-wise? How did you setup the controls to get the vintage sound on your II?

Cheers

Mr. Mohawk, finally got around to your request.

Sorry for the bad pic. I marked up the -CL as the settings were not visible wih the flash. Both have Ultra High on 'cause that's the way I like it. In general, I bump up the bass and roll of the treble to make the II sound similar to the -CL.
 
Thanks for the pic EASonBass! im gonna try those settings tomorrow!

The SVT-II has a different preamp totally, it has 3x 12AX7s in the preamp, and the original SVT had 12DW7s in it. The SVP-CL uses a 12AU7 and a 12AX7 to be the same as two 12DW7s. There are no 12AU7s or 12DW7s in the preamp section of the SVT-II (the only 12AU7s are in the diver stage)
 
I should be receiving my VR this week sometime.

Even though I am a new nerd on this board, I will let you guys know what I think.

I will be using it (for now) w/ an Eden d410t and a Warwick 4*10 that I dont know the model number of.

I am very much a "seeker" right now. I hope this amp has what i want!
 
I found something weird about svt vr. Check out these pictures.

If you look closely, you will see that on the first picture on/off and standby switches have a red led in between and a there's more space between them. On the second picture the siwtches are next to each other and the red led is positioned on the left of on/off and standby switches, a bit lower.

Did anyone happen to know why are there two different pictures on the net of what is supposed to be the same model? Thanks.

My guess is that the MF pic is dated. Probably of a prototype and maybe even PhotoShopped. MF was one of the first to have anything listed on a site pertaining to the VR being for sale.

Thanks for the link to the VR at ampeg's site. Had not seen that yet.
 
Well, my VR arrived last thursday.

I am playing it through an Eden D410T and a Warwick 4*10.

First Impressions:

Definitly seems well made. Knobs are all pretty tight, the switches feel fine and everthing seems solid.

I turned it on and checked out the doo-hickees and light and stuff in the back. The fan came on right away and was very quiet. The Biasing lights are a little confusing to me (keep in mind this is my first tube amp) The manual says that when the tubes are properly biased that the two LEDs will glow green. Well they we both green but only faintly so. I knoticed when playing the bass through it later on that when notes we played they would glow brighter (kinda like a limit light would work on other amps)

I hooked it up sending the 4ohm output to the Eden and that daisy-chaining that to the Warwick. Upon letting it warm up for about 20 minutes finally the moment of truth had arrived. I plugged my 1989 Fender Precision BAss plus into it and let it rip.

Sound:

Now this is where i feel like i might be going a little crazy. It sounded good, dont get me wrong, but I was expecting the total enveloping gigantic-ness that I heard the first time I switched on a friends origional magnavox 1970s SVT (through an SVT 8*10 cabinet). That is not the sound I got w/ this thing. Ok, dont freak, just mess w/ it a little, adjust the eqs stand back from the rig, turn it up turn it down. I notice that when the ultra low is boosted all the good midrangy growel dissapears unlike the old SVT I borrowed. That one just got deeper and more growly.

Like I said, it sounds good but I am not flipping out yet.

So the rest of the band files in, we all oooh and aaah over how attractive the amp is, and it is a good looking beast.

Everybody plugs in (guitar player are bothing using full Marshall and Sunn Stacks. Very loud). Normally one guitar plyer uses a 50watt Marshall and the other guy uses a hotplate on his sunn to make the volume humane. But the 50watt broke, so a 100w Marshall is being used, the Sunn player couldnt hear himself so he took the hotplate off. So now the guitars are so loud I am starting to wonder if I have been rendered sterile by the volume. The volume is so loud that I can see the drummer playing but thats about it.

So naturally, I join the idiocy and start cranking my amp up in an attempt to try and hear myself. At about 1 o'clock Ampeg just sounds like fuzz no matter what I do, the mid control stops working, and I can hear the speaker in the Eden screaming for mercy (not in a good way).

We finish our amazingly loud rehearsal and I am feeling a little bummed. For the amount of money I paid I was expecting a bit more than what I got.

We played a show monday night and as an experiment I borrowed a friends SVT 8*10 to hear what it sounded like w/ my VR. Definitly better. A little more like the old one. So, that leades me too believe that the svt 8*10 are big part of the reason I loved the old one I borrowed (even though the idea of carting that thing around gives me the total heebees).

I still feel like I want more clean head room. A bass player friend of mine keeps telling me to try the Mesa 400+, that it is a great combow of SVT tube gooeyness w/ a more modern sound like a higher watt Eden or something.

So anyway, there it is. Sorry about the meander. I am feeling a bit lost at the moment. I dont want to count the SVT out, but it did not knock me offa my feet like I was hopping.

Here's a VR you won't see everyday... :eek: :eek:

Ampeg%20SVTVR_810AV%20Custom%20White.jpg



Yeowza! :D

Here's the poop from BassNW:

"Ampeg SVT-VR/SVT-810AV "All White" custom built amp system. Besides the systems that Darryl Jones used with the Rolling Stones, Ampeg only made two other systems like his with the all white look. We were able to get both of them and this one is available for sale (the other one has already been sold). The amp head is the SVT-VR model which is a very close replica of an early 1970's blue-line SVT head. The amp features all tube construction and 300 watts of earth shaking tube power. The speaker cabinet is the SVT-810AV anniversary model which has eight 10" speakers and 800 watt RMS power handling capability. This is an instant collector's item and once it is sold there will be no more available (Ampeg has said that they will not build any more). This complete system is on sale for only CUSTOM BUILT SPECIAL SALE - ONE ONLY - $2999.00"
 
So, after two weeks, I am definitly feeling better about the VR. Even w/ the Eden and the Warwick, I got things dialed in a bit better. After a heart to heart w/ the band, I go them to turn back down to humane volumes. So I am able to back the volume off a good bit and it sounds much much better.

I think my only overall complaint w/ this set up is now the cabinets. They just sound to "techie" for this amp. I plan on ditching those two cabinets and going w/ the SVT 8*10. It just has the whoomp and the right GRRRRRRRR (these are both totally scientific terms, trust me).


anyway, just thought i would share a bit more.
