get clean with antistortion...

thoughts?...

that's pretty awesome

A fender tone stack and a volume knob?  Practical I suppose.  It's the opposite of a booster.  Use the amps tone controls to adjust the overdriven sound and the antistortions tone controls to readjust the clean sound.
Normally I don't like fender tonestacks because they lack the ability to boost mids but it works well here.  Better into an amp with James stack I would think.
Very Clever

Every time he kicks the "antistortion" in/out, he switches pickups (and tone/volume controls, as it's a LP)...

genuis !!!

good spoting, however, both pickups are the same (burstbucker 2 ), and all the knobs are on full, so I actually get MORE output when using the neck.p.u. or both...
the fender type tonestack with the values I used, with the treble and bass up a bit, cuts the mids around 500Hz roughly 20db(ignoring what the volume adds(detracts)), something you cant do by simply rolling down the volume on the guitar
a James tonestack would cut bass and treble, but leaving the mids unharmed, doing the opposite of what I wanted. this way, I take away what makes it sound like a marshall on full, and tame the full on marshall into doing something else....obviously, the amp noise is the same, but this is for those of us who play single channel amps...

Haters gonna hate. I think this is supercool! 

[zambo]

yep. I like it too. I made an "underdrive" to use with my single channel amps. Its just a volume knob in a box with a bypass stompswitch  never thought about using the tone stack. Good call on that!

[aron]

I like it!

It's a tongue-in-cheek hoax, right?

Why doesn't someone throw that circuit into the Duncan tonestack simulator and see what comes up?

Why a joke? It will drop volume to the input for sure and the eq will change the tone ( which is good ) but it will clean up a distorting amp quite well i should think. I did it once by putting an eq between to two triode stages running at 9 volts ala the valvecaster and it was a pretty cool eq pedal. worked great.

[Mark Hammer]

Yes, but it doesn't "clean" up anything.  It's a tonestack, for heaven's sake.

[aron]

It's not really any different from a volume knob on a pedal to turn down the level - except there's tonal shaping as well.

[george]

I remember Torres Engineering had a "cut-mids" guitar tone kit that promised to "clean up" distorted sounds by sucking the mids out .... a fender tone stack (which is fairly mid-scooped) would be doing the same thing?

[zambo]

well yeah, and the signal loss causes the amp to not distort on its own as much. that and the tonal shaping give it a cleaner sound. Probably works better on tube amps. It would be cool to make an over/under drive where you could toggle between a sweet overdrive and a antistortion or bypass altogether for the amps natural sound. almost like a 3 channel amp at that point.

[Johan]

it doesnt make an old amp smell like new, no it doesnt...and yes, it's just a tonestack. but it is all in how you apply it. puting it before the amp, the tone gets less distorted..cleaner..
here was the inspiration

I just figured since it needs to attenuate, it could be passive..I normally just turn down on the guitar, but sometimes you also want some toneshaping..

How much noise do you get when you reduce the (already weak) guitar signal before the input of a high gain amp? I've tried to do this kind of thing with a graphic eq with mixed results although some people like that technique.

I havnt used that much yet(it's at the rehearsal space), but the noise is no worse than when turning down at the guitar. obviously, the amp noise remains the same as for the distorted sound, but that too is no different than turning down the guitar, so not a big issue in a "band playing sittuation". for those playing at home it might be thou, but for them, adjusting the amp instead is usually no problem(no crowd waiting mid-song for the quiet break to begin.. )  I would imagine an active EQ with that low output would be noisier, unless it has a volume controll hanging after the electronics

Reminds me a little of a "pickup soak" circuit I built for a friend some years ago

I built a high input resistance gain stage x1 on up to a volume attenuator

My friend was using a 5150 and wanted to use the resonance of the guitar cable input resistance of an amp with the volume control turned up on the guitar but not hit the first stage too hard.

So the circuit at low gain buffered the guitar and resonated with the guitar with the volume turned up, cable, >1meg input  resistance AND this conditioned guitar signal could be turn down at the output of the buffer gain stage so the first stage of the 5150 was not "seeing" as hot a signal.  My friend did not want a cap from in to wiper on the volume control

If you turn down the volume control of a guitar without a bright cap on the volume control you can lose the high end resonance.
