GnomeratronVTF pedal, with clips!!!!!

[McSpunckle]

To be totally honest, I haven't tried it with anything but silicon.

I wired the switch for Asymmetrical clipping... but try as I like, I could NOT tell the difference between it and the signal with no diodes, so I've decided to just switch between different diodes instead.

Generally, though: LEDs clip less. The sound is more open. Germaniums clip more, resulting in a more compressed signal.

This sounds FAAAAR too sick.

Intriguing. What's the first proto got in it? All silicon?

[McSpunckle]

Yup. Silicon. That's standard for muffs. Honestly, the diodes are off-board. People could order whatever they want. Silicon, Ge, Schottky, LEDs... just whatever can be used as a diode in a big muff. It's designed around Silicon, though.

Even freds?

This sounds great.

So far I love every thing I’ve seen and heard.

I don't really even know what FRED's are...

To everyone interested (especially those that have PM'd me about this pedal), I apologize things have gone slower than expected. The circuit is complete, and the graphics are in (and they are -awesome-. The delay is basically that I'm pretty anal about color accuracy.

The official price is $130. I said $120, but I decided to make some upgrades-- notably using real Hammond enclosures, and adding a couple of parts to keep noise down even more. (realistically, only the enclosures effect the price)

ANYWAYS, the first 3 production boards are made (but the wires aren't added in this picture):

[McSpunckle]

So, the way this is going to work, since the pedals are pretty custom... I'll need a 50% down payment to start building, then you can pay the rest when it's done to get it shipped to you.

I'm opening up a list now to basically get in line. You don't need to pay to get on the list, but for your pedal to get built, I will need said down payment. So, shoot me an or PM me, and I'll let you know where you are on the list.

I'd also like to know your diode choices. There are 2 stages, and you can pick any 2 for either stage. Options include: Silicon (standard in Muffs), LED (more output, less clipping), Germanium (more compression, lower output, more clipping), and Schottky, which realistically is about the same as Germanium.

If I had a "standard" set, it would be Silicon/LED on the first stage, and Silicon/Germanium on the second.

Oh, graphics? You want to see graphics?

Choose your favourite. Huge thanks to Jrmy for making them!

This thing is getting a hell of a lot more love on Talkbass (more people, I guess?), but yeah... I figured I'd make the updates here I made there since I am getting a few PMs here.

I promised a write-up on diode differences, so here it is! If you don't want the technical details, please scroll down, but I think this may help you understand how they interact better.

The basic difference between diodes in a clipping circuit is their forward voltage-- that is, the voltage at which they conduct. Basically, when the voltage (volume/gain) of the signal gets above that voltage, the diode will conduct-- usually directly to ground or to a "virtual ground", either way the effect is the same-- the signal clips. So, if the forward voltage is 1 volt, anything above 1 volt will clip.

But but but... we don't care about the technical details! We just wanna know how they sound!

Yes, of course! But knowing how something works makes it easier to understand how it will effect your tone.

When a diode clips the signal more, you end up with more compression and distortion, but less volume. Since this circuit is two clipping circuits in series, if you cut the signal from the first circuit, the second circuit won't clip as much. This is what gives the Muff its harmonic overtones. If you remove the first diodes, almost all of the clipping is handled through the second stage, resulting in a smoother, more compressed sort of sound. If the clipping is only handled by the first stage, you end up with far less compression and clipping... sort of a lo-fi distortion/overdrive kind of sound.

In the VTF, you can consider the octave section sort of an octave-forming clipping section on the first stage. More signal from the first stage results in more clipping from the octave section.

ANYWAYS, TL;DR readers, this is where you stop scrolling.

The diode options are, in order of clipping (least to most):
LED
Silicon (Si
Germanium (NOS) (Ge)
Schottky
Germanium (Generic) (Ge)

Realistically, both germaniums and the Schottky are about the same. The NOS clips a little less, and the generic ones a bit more. Schottky... well... has a different character.

I wouldn't recommend using Germanium or schottky in the first stage. They cut sound a bit too much. Though, having the gain cranked with two Ge stages does have a cool warm tone. I'd think anyone into that wouldn't really be into this pedal for getting those tones, though.

I think the easiest way for me to do this is to go over some combinations that I liked, and if I leave something out, just ask. They're all in the format First stage/Second stage.

Si/Si - Standard Muff configuration. Demos were done with this combo, and basically everything will be compared to this configuration.
LED/Si- More high end raspiness and "crunch"
Si/Ge- Warmer and darker, slightly less volume. Great combo for doom/stoner tones.
LED/Ge- More crunch than Si/Ge and not as dark. Also great for doom or, well, basically anything. This is my favourite combo.
LED/LED- Crunchy, raunchy, loud, gritty, etc. Lo-fi fuzzy distortion.
Si/Schottky- More high end crunch than Si/Ge, and a bit of a more dynamic character.
LED/Schottky- Really cool, interesting crunch.
None/Si- Tons of low end-- almost sounds like there's a clean blend even with the clean blend turned all the way down. Very smooth.
None/Ge- Similar, but more compressed and smoother.
None/LED- Similar to LED/LED, but without some of the crunch.
Si/None- Loud, weird distortion tone. Not much compression. Can tend to "rail bash", which results in a "farty" distortion.
LED/None- More output than Si/None, more open tone. More tendency to rail bash, but not quite as hard.

So, basically, you can see that more output from the first stage means more compression and smoothness on the second stage, and clipping on the first stage generally results in the tone opening up more since the second stage can't clip as hard.

Sorry for the TL;DR... I'll work on a shorter version, but in the mean time, I'll be glad to answer questions or give recommendations for the style/tone you're looking for.

My tests were done with the second proto, a Moser Spawn with Dimarzio Split P/Model J straight to the jack (with a switch, of course), into an Acoustic 150 and Avatar 4x10 (no horn).

And here's an oscillation video:

Nice noisy demo.

Did you steal that bass from Bootsy?

MM

[McSpunckle]

I told him I was gonna add some sparkles too it and ran.

[metalmariachi]

I love it.
Moser makes some really interesting instruments.

It'd honestly be all I played if I could find a decent way to de-metal it.

[veteransdaypoppy]

Okay so the Gnomeratron is a pretty fantastic pedal. It does a whole buncha shit and if I could afford one right now I'm pretty sure I'd buy it. I couldn't find a single non-usable sound from it. You should probably just buy one.

[magiclawnchair]

damn spunckz...

i need to introduce my bc riches to that bass sometime...

oh and great demo too!!!
