The Evil Tone Sucker
Saturday, January 29th, 2011One of my regular readers has tackled one of my pet subjects. The Varitone. Or, more accurately the “evil tone sucking Varitone”, at least to a good percentage of players. Interestingly, there are a good number of nay sayers out there who have probably never played a guitar that has one. The internet is, unfortunately full of “experts” and posers. Unfortunately, they are often the same. Let me say this up front: I like the Varitone. When used properly-that is with a stereo amp or a stereo cable a 2 amps or a stereo cable with a 2 channel amp, it is a wonderful device that gives you a load of useful and not so useful tones. The tone sucking part comes from 2 sources, I believe. One source is the folks who get a “mixer” cable that takes the two outputs and mixes them down to mono. The others have never experienced one-they are bandwagon jumpers. We’ll ignore the latter. Let me make this clear-I’m not an engineer. I can read a schematic and I know a capacitor from a resistor but I’m no expert. A gentleman and regular reader named Chris Wargo is an engineer and he knows his stuff. The reason most of the players who have actually had some experience with the Varitone equipped guitars find the Varitone to be a detriment are using them with a mixdown cable. This will suck the tone out of your guitar when both pickups are being used. I can’t explain this in completely layman’s terms. The pickups on a 345 are out of magnetic phase. When out of phase pickups are used together, you get the difference between them, not the sum of them. Or, to simplify, they cancel each other out since they are essentially the same. Instead of editing Chris’ work, I’m going to upload it and give you a link so you can read the entire thing. he also devised a “true” bypass and supplies a video that clearly illustrates the difference between the built in “bypass” which is position 1 and a true bypass which removes all components to the circuits. I’ll link to that as well. For those who have never experienced the Varitone, it is a notch filter that removes certain frequencies from the output of the pickups of the guitar. In a 345, it is a stereo filter that handles each pickup separately. You cannot, however use different settings on the two pickups. You must notch out the same frequency on both pickups. I suppose you could make it so that you could but that isn’t how it’s designed. The Varitone is used by quite a number of well known players. BB King, Freddie King, Chuck Berry, Alex Lifeson, Bill Nelson, Elvin Bishop, Chris Isaak and probably a load of others I’ve left out. I would note that Keith Richards plays one but his is mono so no Varitone. I don’t know if any of the players mentioned have disconnected their Varitones. I can tell you that there are some big names who love it in that list. Here’s the link to the paper. And the Video. And here’s a big tip of the hat and a thank you to Chris for all his hard work and research. His full Varitone Demo follows because I just learned how to embed video. Who says you can’t teach an old dog…
