Alright here we go. While waiting for the clip to upload, I'll write up the notes.
But first, some notes on the soundclip :
1. The multi is a modified Zoom G2. It already has fizz-mitigation mods on it, so for this experiment, I used Factory Preset 30, but I maxxed out the treble and gain (the two main causes of digital fizz). Please note, I do not operate my multi like this
.
2. Setup is as follows : RJ PRS guitar->Zoom G2-> Passive HC workalike-> Line6 Pod2.0 (set on clean)-> Recording computer.
3. The cap I settled for here is a .022uF. I could have gone for .047 but it takes the max effect to "dull".
. By the way, this is a simple RLC filter with the knee set at 5.6kHz. It cannot possibly match the sharp cutoff of a 2nd order Butterworth filter.
4. There is a volume drop when the device is engaged. Passive eh. On the soundclips this has been compensated for so that the reduction in "kuliglig" sound can be heard and appreciated.
5. The clip has four instances. First riff is without the device. Second is with the device in, but on full open (no cut). Third clip is cut-engaged, but tuned to a sweet spot. Fourth riff is full cut.
So here it is :

1. Again, it will not compete with a 2nd order butterworth active filter. Implementing that on a passive device will result in massive insertion loss. Not good.
2. There is still some kuliglig sound left. But please note, I set the gain of my multi to max treble and max gain for this soundclip. Under normal circumstances (the patches I actually use), there is a sweet spot that can be dialed that's "just right".
3. The cap can be varied from .005uf- .01-.022 and .047. I settled for the .022uF. Different degrees of depth and "cut" can be achieved by changing these out. Series pot was set at 500k.
4. Ah, meron pa pala. Patch 30 does not have cabsim. Turning on the cabsim will increase the kuliglig reduction. Ditto with passing the signal into a real amp and speaker, because the usual high rolloff of a guitar speaker is 5kHz which is quite in line with the action of the device. Meaning, a speaker will actually assist in the reduction of the kuliglig. Ditto if your runninig through a closed back cabinet.
Again, thanks for showing me this.
