Here is a clip of the Electro-Harmonix HOG Pedal doing a sound similar to the Keyboard part
from The Who,s "Won't Get Fooled Again".

What is mind blowing is its done with just a regular guitar with a regular humbucker pickup.
I/4 cable in, that's it!


The Chain of effects was the Electro-Harmonix HOG pedal with a 1/4 note delay and a tiny
bit of Reverb.
The star of the show was the filter effect with in the HOG.
Its a juicy 12dB per octave 2-pole low pass filter controlled by a foot pedal.
Rocked like a WA pedal it made the sound come to life.

On a side note the original sound was done by Pete Townsend playing block chords spread
between the two keyboards of the 1968 Lowrey Berkshire Deluxe TBO-1 organ. The output of the
organ was fed into the audio input of the EMS VCS3 mk1 Synthesizer.

My Guitar-HOG clip is here:

Great job!

It's almost scary that you've started finding ways to recreate your VG-99 synth patches with the relatively simpler, yet eminently innovative (in its own right) HOG.

Amazing as always, Bill! Loved your previous VG demos too.

I wonder how that HOG box works, being polyphonic but with just one pickup... Is it "simply" a question of some very fancy DSP resynthesis coding? How, if at all, is it different from using a VG and hex-pickup with respect to per string separation and control?

It just generates simple waves based on analysis of input. Most likely these are sine waves - I doubt there is any DSP modeling on the order of the VG's going on. The HOG's synthesized output is exactly the same whether I plug my guitar or my cello into it. I believe the use of sine waves is the reason the HOG always sounds like an organ with a synth filter on the back end.

Also, there is some warbling on the generated upper frequencies when playing chords with lower strings. To me, it's just part of the character of the HOG rather than an "imperfection".

The HOG and the POG both work by pitch shifting just like and other harmonizer.
The EHX units do it by running the shifters in parallel.
The freeze in the HOG is just a very quick sample of the input signal.
It truncates the micro loop so it sounds smooth.

Intresting side note , the main designer at Electro-Harmonix used to work for Eventide.

Ah, that figures. Eventide have a coupla really cool pedals I'd like to get my mitts on. Oh, and the HOG or POG too! Cool
