Colorsound One Knob Fuzz + Big Muff tonestack >>> Soundclip !!

[frequencycentral]

I recently breadboarded and built my version of the Colorsound One Knob Fuzz with a Big Muff style tonestack, discuss here: http://www.diystompboxes.com/smfforum/index.php?topic=70498.0

I just debugged it - just one daft soldering mistake. I'm really pleased with the pairing - loads of tones available. Fiddling with the tone control while playing sounds really synthy - so much so that I may have to build a vesion with the tone control as a wah pedal.

Here's a soundclip. through a cab sim. I'm tweaking the tone control as a I play: http://www.aronnelson.com/DIYFiles/up/ColorMuff.mp3

I like it!!

That sounds filthy!

And really synthy too, like you said. Reminded me of a band called F*ck Buttons who do the whole industrial/IDM thing with massive guitar noise.

I'd agree that a way of sweeping the tone control while you're playing would be cool though.

Yeah - but my GF is filthier.............

Reminds me a bit of Matt Bellamy from Muse's sound.

Been driving behind white vans by any chance mate?

Sounds BIGGAR than Muse to me. Cool fuzz though.

I salvaged a mod wheel and a pitch bend wheel/pot combo from a knackered MIDI controller that I've been trying to decide what to do with - thinking they could be fitted in a pedal enclosure?

Yeah - I also have a pitch/mod wheel combo in my pats bin - been wondering what to do with them...................

looked at the schematic in the other thread you are missing a DC blocking cap.

Look close at the big cheese

Ah, you mean the .22 at the output of the original COKF schematic? I'll add it and see what happens..........as I like the sound already I may prefer it without - or is that bad engineering?

I can't find a Big Cheese schematic, only the GGG tribute.......

I just built this up and for some reason I just can't get it to bias right. I've tried different transistors, including the BC108 and BC109 in the Fuzzcentral schematic and I've tried trimpots on the emitters of each of the transistors and I haven't been able to get it to sound like your clip. It has that farty misbiased sound.

I'll have to try it again from scratch and see what happens. Your clip sounds great!

Ahh, did I mention i'm running it on 12 volts? Would that make a difference?

[Rodgre]

That might. I'll try that.

Rick, I was just thinking of tacking on a tone stack to my COKF (since the only thing I hate about it is it's lack thereof) and it seems wiser heads have already done so.

I'm gonna do this for my next build!

Still experimenting with this, anyone?

I do love this one - a really interesting sounding pedal. I didn't experiment with it anymore but I'm planning to breadboard it using LDRs instead of the tone control. One other thing - my schematic only just reaches unity, I've been thinking of shorting out the 2K7 on the emitter of Q3 to see if that gives any more volume.

You should breadboard it before you build it.

.....and I run mine on 12 volts - don't know if that makes any difference?

  I think maybe a buffer between the "high impedance FF output?" and the passive losses of the TC.
  But the think has a serious mud-grit-sand Grind action goin' in it.

[Ssmit]

I can only imagine what this would sound like with a bass. Could you perhaps record a clip with one?

I dunno about a buffer  - some of the magic may be lost!

That soundclip was direct into my soundcard, I really should do another soundclip though a miced up amp. I'll do one with bass too - maybe I'll find time over the weekend.

The idea I do have to take it one step further is to replace the tone pot with two LDRs, each one seeing a LED run off opposite sides of a transistor phase inverter - then the tone could be foot controlled, LFO controlled or even envelope follower controlled.

Now you're losing me!

That fuzz has SOOO much gain on tap, it doesn't make sense that it loses it all after the tone stack if there is a recovery stage afterwards!

But I have to admit I am pretty fuzzy on the whole impedance thing...

Hmmm - that gives me an idea - maybe I should change the gain recovery transistor for a higher gain one than the BC182, that should give more volume.

But I have to admit I am pretty fuzzy on the whole impedance thing...

You and me both - my 'guess' is that because my schematic is..........

......missing a DC blocking cap......

..........it's causing volume loss but creating the 'synthy' feel. Maybe?

You have a 2n5088/9 around?
That's what the BMP has...










you have a 2n5089

Nope - I think I'll try a BC547C.
