Dylan's Precision Fuzz built with the "Manhattan Style" circuit board construction and put in a custom 3D printed enclosure

How's the shielding? I would be inclined to paint the interior with carbon paint

tardy imp
#

I've never had an issue with shielding in my printed enclosures. On one of them I did line it with aluminium tape but all it did as far as Arta was concerned was remove a slight 50Hz hum

unique sand
#

"all" it did was remove all of the 50 hz hum?

tardy imp
#

Well the hum wasn't audible, just measurable. But it's not like I get much other EMI here

#

I've not picked up a radio station yet

unique sand
#

Fair enough

tardy imp
#

But at the same time, if it does become an issue I have a bunch of aluminium tape I can use

#

nice. better manhattan than p2p by far

unique sand
#

The construction is clean

#

is it time for the rule?

If there's no sound clips, it hasn't happened.

unique sand
#

What, do you presume that yeti’s sounds differently broken than yours somehow? 😆

#

🤔 Though considering novel variations of the 431 fuzz … I wonder if it would sound any different to vary the bias current

#

Since the 431 holds a constant cathode voltage

#

Or anode I should say

tardy imp
#

Do you want a demo with amp + cab sim or without?

#

why two, i'm scare

tardy imp
#

One with just cab sim, one with amp and cab sim

unique sand
lost notch
#

do it anyway

lost notch
tardy imp
#

Is the same audio for both

lost notch
#

ok, then the second sounds less broken, maybe it's the copious reverb

#

good though, for a fuzz

tardy imp
#

There's delay on there too, the preset was called "Clean Every Sunday"

lost notch
#

so clean

tardy imp
#

This one doesn't sound appreciably different between my single coils and humbucker which is interesting

lost notch
#

it's past the critical point

#

it's worth mentioning that it cleans up just like a fuzz face

unique sand
#

Yeah but I’m snarking because I’m in a mood and not because it’s funny so

#

I would be interested in how the precision fuzz sounds with a load resistor switch and a buffer

lost notch
#

it's always funny! for me at least

lost notch
unique sand
#

I don’t believe it isn’t but its for me it’s about intent
And yes, “collector” load

lost notch
#

i have a demo for input buffer in/out, even if it's not your usual one

unique sand
#

What I’m interested in is specifically how different collector currents would sound, the buffering would be just for output impedance

lost notch
#

oh that one is good enough that it doesn't matter

#

for collector current, you'd need to separate the effect from bias voltage. for a ground down emitter we know what's left isn't voltage gain but input impedance change, for this i don't know but i don't think it's much

#

It’s also internally more complex than a transistor, after all

#

Probably the broken sound it exhibits is that you’re basically shutting the power off to an op amp every half cycle 😆

#

be TL431
pull my own collector voltage down to 0 volts
.

lost notch
#

that's fuzz for you

unique sand
#

Fundamentally, maybe yeah

#

If we say fuzz “is” blocking distortion, well; this is a form of blocking

tardy imp
#

I don't think all fuzz is blocking distortion

unique sand
#

let's discuss then

tardy imp
#

My 386er fuzzes but I discovered that the fuzz on that is just the chip oscillating wildly and interacting with the incoming signal poorly

unique sand
#

I would assert that the sound of fuzz is the sound of blocking distortion, but you can produce the sound of blocking distortion separately from the phenomenon

unique sand
#

"oscillating wildly" counts as "blocking" just as well as flatlining does

tardy imp
#

Maybe I don't know what blocking distortion is

unique sand
#

in either case the bass components have completely overwhelmed the treble

#

when I say blocking distortion, I mean, "when an amplifier has been overdriven to the point that a small change in the input signal yields no meaningful change in the output"

#

or in other words, "the effective gain of the amplifier is zero, for however short of a time"

#

and I guess "wildly oscillating" counts as "zero gain" for me because it's unrelated to the input signal

tardy imp
#

Hmm so the 386 fuzz either sounds "fuzzy", perfectly clean, or the output cuts out. All depending on how hard you play

#

And all the time it's oscillating at above audio rates

unique sand
#

many fuzzes are known to clean up

#

there is no circuit which is inherently fuzz, fuzz is something a circuit does

tardy imp
#

I agree with that

unique sand
#

and there are circuits which are particularly conducive to fuzzing which we call fuzzes

#

lol pedal philosophy

tardy imp
#

I guess the difference with my one is clean and fuzz can be a matter of playing on one string vs the other at the same volume

unique sand
#

which is no problem because fuzz is a phenomenon

#

this means what makes a circuit a fuzz or not, as well, is whether how you use it is conducive to making it fuzz

#

so, your 386 drive both is a fuzz for one string, and it isn't a fuzz for another string

#

but it might be a fuzz for the other string, if you just played louder

tardy imp
#

Oh it certainly is

unique sand
#

🤔 I feel like this "a fuzz pedal is a pedal that's fuzzing" philosophy carries over well to guitar effects in general

#

too often we try to speak of some essence of a circuit but circuits don't have an essense

#

however the big muff will never be a fuzz

tardy imp
#

I use a big muff as an overdrive more than a fuzz

#

Oh lol

unique sand
#

😤

#

can a muff block?

tardy imp
#

It does get fuzzy though if you crank it and boost into it

unique sand
#

okay I can believe a muff will fuzz if you play humbuckers into it

#

we no longer have to say a big muff is a fuzz or it isn't a fuzz

#

we simply ask when it fuzzes

#

and if it is capable it is a fuzz

#

Fuck it this build is convincing me I should try to use the new big boi 3D printer at my work to make an enclosure heh.. our old ones were small and bad monoprice models which couldn’t handle it but our new one has a big bed

topaz basin
#

have you designed the case model yourself?

tardy imp
#

I did yeah

topaz basin
#

oh, thanks, i might do some edits and try it out

topaz basin
#

what program did you use?

#

for the modelling that is, im running into issues on translating the file to onshape

tardy imp
#

I used onshape

topaz basin
#

could be that im using the wrong measurement unit, what did you use?

tardy imp
#

Mm
