EQ Phase in Parallel Processing Test

This video taught me about phase change in EQ.  It freaked me out a bit because I’ve used plenty of EQ in parallel processing during mixing on reverb and drum compression sends.

I did some testing in Reaper that reassured me that I haven’t made egregious mistakes in my mixes. The phase change around an EQ’s cutoff frequency is worth keeping in mind, but doesn’t drastically affect the summed output of signals in parallel.

What you see above is my test Reaper session.  Fuzz’s song “Rat Race” is on two tracks playing in parallel; one has a high pass filter at 500 Hz (the top plugin window) and it’s phase change is also displayed as the orange line.  You can see that the EQ’d signal is somewhat out of phase with the unprocessed signal well above 500 Hz, potentially resulting in phase cancellation above 500 Hz when the signals are summed.

The spectrum analyzer (lower plugin window) shows the summed signals (the green background spectrum) and the unprocessed signal by itself (the pink foreground spectrum, which mostly looks lighter green where it’s overlaid on the summed signal).

What I notice is that the difference between the original (green) and parallel-processed-and-EQ’d (pink) signals diverges right at about 500 Hz and the difference is pretty consistent above that point.  For me, this is great news; the parallel processing behaves almost exactly as I naively expected it would, before I knew about the phase change described in the video.

A bad result would have been if the difference between the green and pink spectra began diverging around 500 Hz but grew slowly, up to 5K or 10K.  That would have meant that in my mixes, I was losing information between (in this example) 500 Hz and 10K without realizing it or compensating for the loss.

tl;dr – Sighs of relief and feelings of bullets dodged in the Studio/Laundry Room of Fury.

Nothing Like…

…shooting material for two videos, then realizing there’s something wrong with your camera.  :-|

Hopefully next week.  Taking off in an hour for Omaha and the DS show tonight.

Rainy Saturday Pedal Building

This afternoon I’ll be building the first Giambattista Tremolo in a one-off custom enclosure courtesy of Seth M Jones.  I did the LED and bypass wiring yesterday to give myself a head start.


The Giambattista is based on the old Jordan Vico Vibe (and a layout by Nicholas Kula).  I’ve added a JFET boost and volume control on the output, which others have done with this circuit.  I’ve also moved the bias (which affects the pulse width) control to the outside of the enclosure, and added a fast/slow rate range toggle, which I haven’t seen done before.

The Vico Vibe is a great, vintage-sounding tremolo, but the knock on it is that the rate range is fairly narrow (and quite fast, with stock components).  The Giambattista, with its fast/slow ranges, will go from faux-ring modulation fast to obscenely slow.

More videos on the way once it’s done.

Falcon vs. Falcon Heavy

Here’s a comparison video showing the MOSFET (Falcon) vs. silicon (Falcon Heavy) clipping and low-mid (Falcon) vs. Russian Muff mid (Falcon Heavy) cuts on guitar.

What I didn’t show, and should have, his the higher gain range on the Falcon Heavy’s silicon setting. In the first comparison the Falcon’s drive is dimed, while the Heavy’s drive (out of the picture) is at maybe 65-70%.

This is to help guitarists who want one to choose between the Falcon and Falcon Heavy. I recommend the Heavy for bassists, *unless* you’re going to leave the pedal on all the time; in that case I could see a bassist going for a Falcon, especially for a more vintage sound.

Falcon Drive Demo

Sorry again about my dumb socks.

Happy Belated 50th Sparks


I had a head off of my gold sparkle kit last night preparing for the Dark Satellites show, and saw the stamp marking it manufactured in February 1966.  So, happy belated 50th birthday to my drums.
