One time my power supply stopped working, just before the gig. I was really pleased with my SansAmp PDDI working on phantom power. It is one of the (many) reasons I keep it on my pedal-board.

I have read phantom power can only deliver 10 mA (or maybe a bit more) so it seems safe to say the Elite will not work on phantom power.

if the voicing is too extreme for you (what i completely understand) you should try to just engage the air filter. in contrast to what the manual says, it actually works close to a "voicing off" switch, because it almost neutralizes the big midscoop and bassboost.

This is what the paradriver looks like with blend control fully clockwise:

and this is what it looks like with blend fully clockwise but with engaged "Air" (you can ignore the stuff above 7khz, i suspect this is just a glitch in my measurement):

you can hear what it sounds like in my video at 13:45:

i hope this helps :)

PS: no wonder the rumblefilter makes a huge difference. this is what it looked like in my comparision:

Wow. That's really interesting to see about the "air" switch. I'm assuming all other eq was at noon. That's a great starting point with the Paradriver. I used to own the original and it was a great sounding and useful unit. I also used a VTDI for a couple of years, with great results.

i only discovered that and how useful that could be going through the recordings after i already sold it. Yes when i measured air here, blend was on full and every eq control at noon, drive set to unity gain and as clean as possible. At least no audible saturation

I'd like to do this kind of analysis - what kind of HW and SW does it take? Something that sweeps across frequencies and tracks the transformation as it goes?

Not a lot really depending on what you already have. The hardware needed includes anything that can send and receive an audio signal with some degree of accuracy. For me that's as simple as my re-amp box alongside my audio interface.

For some the audio interface alone might work (YMMV), but I believe having the re-amp box turn the signal back into a signal with an impedance more like that of most basses gets me more realistic results - this is more true for some tests than others. I already use the re-amp box for actual re-amping anyways, so it's just something I already was using. Even just the audio out and mic-in of a computer could work, but some line level signals can get pretty hot so you might be missing the necessary headroom, and there's also the risk of damage if care isn't taken.

As for software, I've used TrueRTA for ages, though there are other such "RTA" (real time analysis) options available. possibly even some free ones in this day and age that you might be able to find with a little research. I've heard some recommend REW (Room EQ Wizard) before, but I have no experience with it myself.

Edit: thinking about it a bit more, if you're able to generate your own test signals, even something like the visualization in Voxengo SPAN or ReaFir should do the trick, especially for more simple explorations.

I'd like to know where the HPF is set on the VTDI as well. It seems terribly high. It's way thinner sounding than plugging directly into my board with the HPF set to 60hz.

See below, I've always believed it to be a rather shallow roll-off starting around 80Hz as this shows. IME the thinness may perhaps be due more to the way that the VTDI can accentuate highs if you don't EQ them down a bit or boost lows a bit, more so than the effect from the low end roll-off via the sub filter.

And for the record, these were the settings I was using with the above - bite and cab sim on (this is important, as the strength of the low end roll off unsurprisingly is tied to the speaker sim).

this is the curve i got comparing blend 100% and everything else noon, no bite or cabsim, to the direct signal (not the bypass sound i have to say).

One thing to note, as I try and recreate this, keep in mind that drive can generate a good bit of compression via distortion depending on your signal strength and how you have drive set. I do see that your return signal is very low at ~-60dB, but it's also possible that's being compensated for on the back end, so I thought I'd mention it.

When I use the same settings you indicate above (see reference below) with drive at zero so it doesn't compress the results, it looks like the below. One thing that definitely jumps out to me is the level of singal you're still showing at the extreme high end at around and above 10k. I wonder how much noise might be included there depending on how you're routing the signal. Apologies if I missed it, but what test signal are you using for this?

Blend 100% CW, EQ Noon, Character Noon, Drive 0, Bite and Cab Sim Off.

Now, watch what happens as I raise drive up from noon.

Sweetwater now pushes Elite availability to June. This is such a s****y business practice as it affects the consumers end, T21. Why must you take $ half a year before availability? Same deal with the XB.

They took money? I was able to pre-order the new Amalgamation by Tech 21 without paying anything. They just called me before shipping it and that's when I paid.
