This seems most obviously to me not to be an actual bass guitar but a keyboard bass. This is just a synthesizer patch to create that. No big deal really. Of course you might be able to create this with an actual bass guitar. It appears to be something akin to tube distortion/saturation. And there are plug-ins for that in software. Of course creating that sound with hardware may require a tube direct box? Along with some limiting/compression both or either. And some low-cut a.k.a. high pass filtering to keep it from getting far too muddy. It has to be able to cut through as demonstrated by Coldplay.

Tubes are cool for soft saturation

Thanks for the reply, I was actually hopeing it was keyboard bass because I was doing my bass through keyboard bass. Do you have any recomenndations for tube distortion/saturation for bass's? I have some plug in's but I'm not sure if they're specifically for bass or not.

Thanks again

Many of those plug-ins designed to emulate tube distortion/saturation showed will be able to accomplish that emulation. It might just take some tweaking on your part to get it to sound that way. You might have to roll off some high end? And some low-end? What we commonly refer to as bandpass filtering which is simply a restriction of high and low frequencies along with you utilizing that plug-in. You may need to filter before the plug-in or after the plug-in or both. What you don't want is actual clipping which is usually symmetrical, odd order harmonics and dissonant sounding. What the plug-in is designed to do is create asymmetrical saturation without flat topping the waveform yielding greater second harmonic content. And that's musical saturation.

I might drink this whole bottle of cheap Andre Champagne which will cause a different kind of saturation?

What type of settings for the bandpass filtering, everytime I try it it takes way to much away from the low end and high end freqs. and it doesn't even sound like a bass?

Bandpass filtering with your software may have fixed high and low frequency roll offs? I really don't know what kind of software you are using since I'm not accustomed to it? It's like asking me right now what's wrong with your car. I don't even know if you have a car? Doctor it hurts when I do this....? You may or may not be able to adjust your high and low frequency roll off frequencies? I utilize Adobe Audition quite a bit which has numerous different kinds of filters one can use. All of which are completely and totally adjustable. In fact they go way beyond what any hardware devices can do. So I want to use by filtering to create a bandpass filter to approximate the sound of a telephone, I must brick wall filter at 300 Hz at the low frequencies and 3000 Hz at the high frequencies and voilà, telephone like sound. Conversely, If I want to approximate the sound of AM radio, I would brick wall filter at 50 Hz & 5000 Hz and you get the sound of AM radio. So if you have the ability to adjust your cutoff frequencies, you could better select what frequencies you want to filter out. If it's a fixed frequency band Pass filter you may be stuck with that? So you would have to use some other kind of adjustable filter i.e. equalizer. Which is a generic term for a tone control, graphic equalizer, parametric equalizer, etc..You might want to also read your manual and/or the help file in your software.
