What's pre with tons of bottom

Sure--GreatRiver Me1NV.

DanK actually walked me through how to wire up some caps in the insert jack to work as a HPF because there was such low end extension and girth everything was huge....other "neve clones" I've used did NOT have that quality. Even when you filtered it, down to the filter is was SO "huge" and solid that you could filter it at 150hz or something and still have "lots of lows". Ultimately, I'd love to have kept it, but it NEEDED the matching EQ. I would love to have that channel, but the EQ price was too steep....and I felt like a preamp I NEEDED to EQ all the time wasn't really right one for me.

What on earth is lacking low end for you? I want a preamp that starts gently rolling everything at 240hz....

To my ear the Lola sounds kind of like that in examples, I've never owned one though.

My SCA N72 is the bottomiest preamp of my stuff, much more than the API 312 type.

I remember the 3124+ having a pretty big bottom, too. (or 512c).

a tape simulation plugin is a good shortcut to this kind of sound, too, or certain compressors. I've just used Kramer Master Tape to good effect.

im looking into a kickdrum pre, the api style isn't beef enough for me there, but only there. I may just build a single Dons classics NV73, or a pair of lola's, but i need to hear winetree 's first!

1073/1084 and appropriately designed clones. HUUGE bottom.

Even if a preamp/audio device rolls off at 20 hz, you will have phase shift that increases with lowered frequency. It will start the phase shift at 200 hz. This creates sloppy bass, that is a bit tough to tighten up.

If the roll off points are set to 2 hz, the phase shift kicks in at 20 hz, not audible. Then all your harmonics line up in the proper order as well.

It's not only the spectrum or frequency response that sets the amount of low end depth you have, it's also the phase alignment. Neve 1073 designs usually have about 50 degrees of phase shift at 20 hz. Not my first choice for a solid low end.

Add to that the phase shift isn't linear either, it has a deviation from linear phase which causes more time smears.

One mans great low end is another mans phase shift!

Bill that's why we have Mr Eric's first 2 rules of audio ( ah hell life in general)
1. Never Knock what works!
2 It's not how you got there, it's that you got there.

Yes having some understanding of why and how something works and what that means in sonic terms helps., and I do appreciate Guys like JIms per suite of sonic perfection, but 99% of the clients I get don't really want anybody to hear what they sound like they pay me to make them sound like they wish they sounded!

Really thinking about 60-100 hz. I would imagine the Neves probably are the goto's.

I can't think of any time outside a kick drum I boost that range at all. Quite the opposite. That's really why I was curious.

So now we know a Nevish pre is great not only on vocals and but for kick drum as well.

Not trying to be a wise guy, but I think a U47 FET might accomplish what I think you're looking for Tony.

I love the Heritage Audio 1073 with EQ, but cant's afford it.

I regularly use UAD's Pultec plug on drums, then dial in the fat by ear. On vocals, their LA2 thickens things a bit if you like it..

I have a Great River and love it!  I love every bit of lower end beef it gives, but you can control how much you get by how much gain you call up in the first stage of the amp.  I use it with a decent but hardly vintage style tube LDC and it gives a really big vocal sound. 

Note that it's not just more low end, it's gives the overall sound more weight, or would "dimension" be a better descriptor?  I really like how it flatters the SM-57 and SM-81 mics.  I think in both cases, it has enough gain to drive those Shure mics notorious for needed lots of gain.  I bet SM-7B fans would love it.

Last, its a terrific DI for bass.
