get clean with antistortion...

[DougH]

I found a cap and resistor in parallel to work the best on the guitar vol, for keeping the treble consistent over the range of the pot. It's difficult with an uber gain preamp for these kind of techniques to work because there is so little headroom available. One advantage I see with the antistortion is the ability to scoop the mids, which is where a lot of the freq resp is concentrated in a high gain sound. If you scoop the mids in an amp it's easier to get it clean up using the guitar vol, but it doesn't necessarily make for a great high gain sound.

IIRC back in the early ampage days there were posts about the

That's a name I haven't heard in a long time. I remember Gil from ampage. I remember that device too. Looks like a "distortion/eq fixer" for fenders or boogies. I'd be willing to bet the goal is to make the amp sound "Dumble-y", from reading between the lines. Seems like you could use a graphic eq to this kind of stuff.

Sounds about right.

He posts at Amp Garage from time to time. We big into the boogies for many years now he is all about the Dumbles.

Gil is a Larry Carlton expert. He knows more than anyone I know. Maybe more than Larry!

From the manual: "Next, set the left knob to SMOOTH.  This position implements a first-order
realignment filter that affects carefully selected portions of your guitar signal's low
end."
Uh-huh. So its a cap and resistor?

That tonestack-in-a-box is a pretty cool idea! I used to have a "clean" switch on a previous guitar I built. Just a resistor and a cap. (I forget the values) Cleaned things up nice, but it was not adjustable. I might try this for my current gig, as I have been kind of doing things backwards lately. My current guitar is a single P90, mid position. (another home-build) Playing it through a Supro, the sound is way too fat. (even for early punk) I'm finding myself leaving my guitar volume at half all the time, (with a treble-bleed) and then having to stomp on a boost pedal for solos. The Antistortion looks like a much better solution, and it can be re-tweaked if I change guitars. (got another cheezy home-build on the way)

This just seems too simple...

I gotta toss one of these together just to see what happens.  It would be great for getting in and out of tricky parts where you really can't get to your guitar knobs, and as noted the mid "de-hump" is the game changer.

Thanks for posting this.  If it works half as well as the demo and Gilbert's idea this will be a cool secret weapon.

I've been following on the phone. Just checked your demo on the computer-wow, impressive! I can see how this could be pretty useful. May try it with my uber- gain amp just for fun.

OK I tried this out tonight on the breadboard. I added a jfet buffer on the input so I wouldn't need a buffered pedal in front. It worked pretty well, even with my ultra high gain uber-preamped Windsor (think SLO or 5150 gain levels). The only issue was it did not have enough highs for my taste, it sounded a little dull. I think this might benefit from scaling the impedance lower, with a buffered input. I think the 1M vol pot might be a problem.

So I tried another idea. I used my DOD 7 band graphic EQ, scooped the mids and attenuated it all the way down. Unfortunately the -18db available wasn't enough for this preamp. So I simply used a 10k vol pot on the output (on the breadboard) and voila, works great! In fact I can't believe how good the cleans can sound in this amp with proper EQ. Even with the treble turned down to smooth the distortion, with this "clean" circuit engaged the highs are crystal clear. And with the PAF humbuckers it can completely clean up. Sometimes it sounds louder clean than dirty, probably due to lack of compression.

So I'm thinking I'm going to mod this EQ with an output vol pot so I can attenuate it for this. Very cool, now this amp has a clean channel and it sounds fantastic! Thanks for the inspiration.;-)

i just saw this on ebay... looks like anti-stortion to me...

Most pedals I see online are copies of ones I find here. Maybe this one? Maybe not!
