Title: Confessions of a filter whore...
Post by: raulduke on December 11, 2012, 04:38:39 PM
I built the Nautilus recently; love it.

Bought a Subdecay Prometheus; love it.

Built an MS20 filter clone and a SVF; love em.

This is not counting all the other filter based projects that I have owned, built and have yet to build.


Now I just boughted myself one of these bad boys as an early Xmas present (to myself  ;D)

Sure, I'll help you find some more projects!

Have you built a Lightwah yet? ;)

Ha ha I know right; it never ends!

The next big one for me will be a Moog Ladder Filter clone I think.

The pedal I have bought (the Koma FT201) has a built in IR motion detector, which is patchable, and outputs 0-9V. The sequencer is also patchable for use with other stuff.

Its sort of a semi-modular pedal, so I figure I will be able to use a lot of the features for loads of stuff.

I am going to order a Nautilus board soon.  No filters on any if my boards yet.  A crime against the envelope.

I am well on my way to being one also. The Nautilus and Honeydripper boards showed up today. I already have:

Dano French Fries

Have Built:

SWAW
Meatshphere, need to dial this one in
Nurse Quacky with LPB as pre gain

Also working on a Systech Harmonic Energizer, just have to drill the box and wire it up. So can I join the club?

I think Brian's trying to enable your addiction, as two more filter projects made their way to the projects page today (Junk trunk and junk trunk jr).

Nice one.

I think I remember reading something about the Mutron Micro-alike on the forum.

Another one to add to the list  :D

Other than the Systech (gets used regularly), I love filters but can't figure out a way to actually use them in a live setting. I'm not coordinated enough to effectively use a wah. I'd probably bite my tongue or just fall over. The HoneyDripper, SWAW, MXR, Quacky, and Filter Sample/Hold are all very cool but get no love from my pedal board.

Oh, and of course I'll still keep building more...

I bought this more for processing other things (drums, samples, loops etc.).

It's more for my studio rig/setup than it is for my guitar.

Although using my guitar with it will be fun as hell  ;)

Since this has been brought back to life, did you build a Moog Ladder? If so, what did you use (project, PCB, etc)? I think I need to build one.

ooooh, nice!!

I am with you on filters. They are also my favorite.

Can you tell me how difficult was the MS20 filter clone?

I currently have 7 filter pedals that all use once in a while....

Steve, seriously build Brian's Kraken... for the simplicity, it's unbeatable.

That really needs to be put in a 1590a.  I'm just saying....

Do your filters light up, and come with a translucent front panel? :)

(Got one in the In Progress pipeline. I still have to get a psu and a case, mind you.)

Frequency Central FTW!

They also do a Moog Rogue filter and VCA clone which is a ladder filter I believe.

That's next on the list for me.

Rej; got the Kraken lined up and ready to go. Need to get some of the special parts in for it though.

In other news, I blew up two VTL5C3's last night prototyping a TI filter chip  :o

Thats £8 down the pan  :'(

Thats right. Sounds ok but nothing to write home about. I'm not sure how much they cost either (got samples from TI). That could be the decider!

May be cheaper just to use LM13700n for filtering duties.

Hehe, LM13700 is magic, my favourite IC at the moment.

oh... and forgot to mention: http://es.mouser.com/ProductDetail/Texas-Instruments/UAF42AU/?qs=sGAEpiMZZMuo%252bmZx5g6tFAPp%252bHcYlYz3

if it is about cost, then UAF42 is a dead end...

Soldered up a MS20 filter based on Rene Schmitz's schematic, in Eurorack format. I don't have a front panel for it, so no build report yet.

But damn this thing sounds good. Filthy, too -- I think it would work well with overdriven guitar.

I added an audio input pot for Lowpass, as per Scott Stites' recommendation (couldn't work out how to get the Highpass to be both switched-jack and also have a pot on the input.) Other than that, as per Schmitz's schematic (down to the CA3080's -- bought 25 at some point, still have 23 left.) Edit -- fabbed boards, too :) two stacked ones, as per my Minimoog VCF 2.0 build.

It's fun looking at how the LED clippers in the resonance feedback opamp react to twiddling the Resonance and Frequency pots. Resonance controls the brightness, Frequency controls how fast they blink :)

Nice!

I would love to build and MS20 filter for my Eurorack.

Here is my standalone unit running on +/- 9V. It's the Rene Schmitz but with a preamp beforehand (SHO) and using LM13700 rather than CA3080

Got a Madbean Kraken waiting to be boxed up as well. The filter obsession never ends.
