    what do you think about putting together a sansamp RBI and a power amp? I see some of you have a similar setup, but my question is...

    will it really replace a SERIOUS amp?

    keep in mind that I could be planning to replace my marshall vba400 all valve head with the sansamp/power amp duo.

    Well, if you don't put a power amp with a Sansamp RBI, the RBI won't make any sound at all :smug: Seriously though, an RBI is just a preamp.

    What do you mean by SERIOUS amp? If you mean volume or wattage, if it's hooked up to a decent power amp it will have far more of both than your Marshall has. The only difference between using a preamp+power amp rig and a one-piece head is that the pre/power amp are stored in the same unit on the head.

    It's a great setup--I play 4-8 gigs a month with a QSC PLX 1202 and a sansamp RBI. The sansamp does not sound exactly like a tube amp, but it doesn't weigh as much or cost as much. The eq is flexible and powerful. It's definitely a serious amp rig.

    I'm happy with mine--I may buy an SVP-CL preamp, just for comparison. I sometimes think I miss real tubes. But really there's no need--the sansamp is fine.
     
  4. Brief Hijacking. sorry
    Bryan, your art is wonderful, great site too.

    Panazza,
    Preamp Poweramp set ups are great and versitile.

    I am not talking about voulme and wattage... I am talking about sound... I mean... does the sansamp sound good compared to a serious amp?

    I know that the sansamp is only a preamp.... :rolleyes:

    I could even afford an ampeg tube preamp, but I think the sansamp could be more versatile... I find the ampeg sound a bit too muddy, and I hope I could shape a different sound with a sansamp...

    Ive had my Sansamp RBI since christmas. I'm running with a QSC RMX 1450. I really like the way it sounds and it gets really loud. It has good tone, easy to get a sound you like and doesnt weigh alot. I would reccomend it.

    I didn't mean to sound condescending-it's just the way you asked "what do you think about putting together a sansamp RBI and a power amp?" made it seem like you thought it could be run without one.

    Oh, and thanks Big String!

    Take my opinion with a grain of salt as the Sansamp that I have is the BDDI, which is basically a non rack version of the RBI, but without the mid control.

    My BDDI sounds fantastic. I've stopped using it as a preamp now that my Mesa/Boogie head has shown up, but it did a damn fine job before that. There are two things that I didn't like about it as far as tone is concerned. The bottom end on this thing is huge, its very easy to dial in a huge serving of mud if you're not careful. The other thing is that the highs can become overly bright, clangy (if that's a word), and sometimes harsh. Finding the right combination of the treble and presence controls is sometimes tricky depending on the situation. Overall I think they do a great job, and the two "issues" I mentioned are easily resolvable once you get a hang of the EQ and realize that a little adjustment equates to a huge tone difference with this thing.

    Provided the RBI is similar to the BDDI in those regards I think it would be a great setup.

    just to understand my situation...

    I am renting this huge marshall head and I'm planning to buy it.

    but I often play at low volumes, so I can't push the valves like they should be, and I am worried about the cost of valves to replace... and this head is fragile, heavy... and too powerful.

    So, I know the sansamp won't sound like the "real thing", but I must consider other factors above than sound...

    and I don't know what to do....

    My rig is basically a sansamp-poweramp rig. I'm thinking about getting a second sansamp to run dirty/clean. It's a great preamp.

    One of my gig rigs is a SansAmp RBI into a power amp. To answer your question: it *is* a "serious amp".

    The RBI has a certain tone to it... some like it, some don't. So, while I happen to like the RBI, you might not. This is true for any piece of gear: for example, not everyone would buy a Fodera even if s/he could easily afford one.

    and what about this instead of the sansamp?

    real tubes here...

  14. I think the Ampeg would sound great,I loved my SVT back in the 70's.That being said I also love my RBI/Crown pre-poweramp setup.It's more versitile and gets a good SVT type tone plus a good clean sound if you want.Definitly a serious amp.Either of those preamps with a good poweramp would sound great.

    one thing to consider. the effects of preamp tubes and poweramp tubes are quite different. you may like the marshall sound due to the tube poweramp section. the amped svt cl is a nice preamp, but using that with a solid state power amp wont sound like using an svt classic head.

    i'm still wondering what a "serious" amp is...........

    well, I need a solid state power amp... I love the sound of a valve power amp but

    a)I can't afford valve replacements
    b)I usually play at low, very low volumes... so low that I can't even push the preamp of the marshall...!!!

    for serious amp I mean something that...well I don't know! :p

    my laney 120w combo isn't a serious amp...

    my marshall head is THE AMP... :D

    you might be happy with a 100 or so watt all valve amp. that way you get the sound you like at the volume you play at.

    and you really dont need to replace valves all the time.

    ya, tubes act like a valve is the way they operate, hence the brits and others on that side of the pond call em valves.

    I run an RBI, along w/an RPM, and a BBE BMax Tube, into a Carvin DCM2000. The RBI [as with any of the other pres i own] is capable of sounding amazing. I like it-i like it far better for electric bass than upright [the RPM sounds a lot better for upright]. Nice and versatile-plus it's small, light, and there's very little that could actually go wrong. That's all
