Yes, so its bullshit.
What's bullshit exactly? FWIW, NAM models are extremely accurate. Can you guess which is the amp and which is the capture?Yes, so its bullshit.
So you then have the real thing, why do you need a sim?
Hey, its your money! But by my understanding of it, you have to have the amp to make the sim of it. So you then have the real thing, why do you need a sim?
It's about convenience, flexibility, electricity bills, amp tech costs etc.Hey, its your money! But by my understanding of it, you have to have the amp to make the sim of it. So you then have the real thing, why do you need a sim?
I did another little DI test, with larger DI tracks and multiple guitars and basses recorded, the differnces become even more apparent, but let's keep it simple for now with rather short DI clips of a single guitar and fairly repetitive playing. Here are the clips, level matchd and sample aligned, so that you can make the Null Test yourself (you just have to flip the phase on the EMG 81 DI and play it simultaneously with each of the other wav files and then measure the integrated dBFS at the end):A couple of obvious usage scenarios come to mind:
a) A SIM supplier would use this to produce / QC Sims produced.
b) You have several amps but can't take them where you are going to play for practical reasons. So you are going to go the SIM route and want to check the SIM with this.
But I'm not certain I fully understand the OP's problem. It seems the response with the DI in question is inconsistent. Not necessarily sonically poor ? If so this should show up in repeat measurements with eg REW. Are the differences audible when playing guitar through the amp or listening to the test tone ?
I don't see a mechanism for variability unless build is flakey. It does sound like a level / impedance issue ???
The Palmer's getting -44.5 dB in the Null Test (after I phase flip the DI track and play both the palmer and DI track simultaneously) and the Jensen's getting -38.4 dB, so quite a bit worse.
it has nothing to do with a high noise floor
