If I have a Boss GEB 7 would a Sansamp Bass Driver add anything?

night and day difference, the bass driver adds actual tone character and serves as your "bass amp preamp". the EQ is just an EQ.

 

They will give you more dirty tones, but more tones overall? That I don't know. OTOH, how many tones do you need?

 

Not so much fuzz, although it will get pretty gnarly if need be. Personally, I favor the VT over the BDDI for dirty tones, but the BDDI is simpler to use.

 

More OD, a bit of compression, a different kind of EQ- shelving, with a "presence" control. The graphic EQ is a much more specific tool to address resonance frequencies or dead frequencies on your bass, rather than an overall tone shaper. I think a pre would work nice with your EQ, check out the Tone Hammer as well as the SansAmp BDDI, among others.

 

The Sansamp BDDI is brilliant, gives me that tubey warmth missing in my SS amp. LOT'S of tones from this, from gnarly Geddy to mellow James Jamerson and all stops in between.
I had mine for less than a few hours and had these two sounds nailed plus some Entwistle type distortion as in My Gen happening, very happy with what it adds to my somewhat sterile MarkBass amp. Get the Sansamp Programmable BDDI, it has 3 presets you can switch between and alter as you wish. The manual has some good preset templates too.

 

Bass Attack. It's a very cool preamp pedal, too, but it's way different than the BDDI or VT, which are Ampeg simulators. I call the Bass Attack a Hartke simulator The overdrive it gives you is quite different...very mid-scooped and hard. But it can be mellowed out by adding clean blend and it sounds quite good for certain things.

 

Welcome to the rabbit trail that is "My Tone". You'll find it, then it will evolve, then you'll find that it doesn't matter because you're lost in the mix. Then you'll revamp it and find something else. Then another company will come out with a new pedal that'll be the new "be-all-end-all" to your tone.
Then you'll go back to basics and stick with one pedal and an amp. And then you'll come full circle and regret selling that one pedal you had 8 months ago.
And then you'll make a post about how much you miss it and are strapped for cash so you ask for recommendations on cheap knock offs of "that" pedal".

 

They're amp simulators AND overdrive pedals. What makes the Hartke different? The mid-scoop and the tightness. The Hartke really doesn't do fuzz, but it'll do a pretty intense overdrive. They're all different flavors of the same thing. And I've seen that Behringer comparison before, but I think the BDDI sounds better, and I greatly prefer to stick with the company that originated the BDDI out of principle. That and Behringer really cuts corners in the build process.

 

I use the sansamp GT2 rather than the bddi. I love it for what it does, but I get a very specific tone that Im looking for out it. I use the Eq pedal for specific frequencies that are too much in abundance or not enough on some basses. Also, the GT2 is part of my effects chain and only on one of the amps. The eq I put in before my amps and pre's on both the clean and dirty amp. I usually just use it to tame down a nasty high mid surplus on my spector 5 in passages that are on the upper strings. or to boost highs on my dean as its downtuned to the point of ridiculousness for one project.

 

GEB7 with the Sansamp would be pretty nifty, as you could use the EQ to boost mids that are otherwise missing from the Sansamp's tone.

the Behringer clone is not bad for the money, for the record - you generally don't need to stomp on it, as it is by nature an "always on" pedal. the Sansamp has superior build quality, of course, and is better suited to touring/general abuse.

 

go for it - the price is good, and the sound is pretty much the same. just don't drop it
