Helix Floor to Helix Stadium Agoura Amp Models

[amsdenj]

I captured a bit of Steve Sterlacci's video: 

 and imported into Logic so I could use Match EQ to learn more about the differences between Helix Floor and Helix Stadium Agoura amp models.

 

Steve clearly demonstrates the long known issue with Helix Floor having a somewhat odd high-end emphasis (sometime call squirrels, fizz, ice-pick, etc.) that needed to be tamed with pretty aggressive high cuts in the cab block. The Agoura amp models don't see to have this emphasized and somewhat tiring high end. 

 

We can use Logic's Match EQ to get a better idea what EQ would be required to make Helix Floor more closely match the Agoura models, and maybe be better informed about how to EQ Helix Floor to tame the high end.

 

The Match EQ graph is quite interesting:

 

As we might have expected, there's additional high end in Helix Floor starting at around 1 kHz, gradually increasing to about 8 dB at around 6 kHz that Match EQ is cutting. What's surprising is the significant boost in the "air" frequencies about 6 kHz and up to 20 kHz. That could be part of the amp models, or the better hardware in Helix Stadium. Now I captured this off a YouTube video, so I don't expect the audio to be that great. And I only matched one sample from the video. So this might not be that accurate. But it perhaps gives us a starting point to know how a little more about how to tame the Helix Floor's high end.

 

So try it, using a high cut at say 5 kHz, or parametric, graphic or even global EQ to match what Match EQ is suggesting. This might breath new life into your Helix Floor.

Wow, what an interesting endeavor!   Thank you.

The underlying assumption here is that they modeled the same Deluxe Reverb specimen twice.

 

I highly doubt that and would bet money that these are different Deluxes.
