Re: Q filter What does it do, exactly?

I have two Tele guitars. They are both wired the same and use a Stew-Mac 5-Way/4 pole Super Switch. One the first guitar I have Lawrence 200's for both the neck and bridge and want to switch to the 298 for the bridge to get an overdriven sound. However, I also want the ability to have a non-driven sound from the bridge (a la the 200's) and thought a Q Filter could accomplish that. Will I get what I am looking for with the 298 and Q Filter?

My second question is: How do I...

Hi I'm Larry.

I have been following your online discussion of Q filters. This might be the answer you're looking for. The Q filter in electronics is a filter that will vary the Q of a circuit. The Q of a circuit means the QUALITY of the circuit. This is usually used when talking about filters and tuned circuits and their band widths. A filter has a band of frequencies made up by a group of components usually a coil cap and sometimes a resistor. This group of components...

I'm not an expert, but a cap generally filters out high frequencies. Higher value should mean less highs as the knob is turned down. I only assume that this is how it works with the Q-Filter.

So Q-Filter with cap and resistor, as you turn the pot anti-clockwise I think it should have the effect of reducing highs via the cap, yet retaining the preferred amount of bass via the resistor, all the while lowering the inductance (power) of the pickup. I think.

Thank you!
So... what about cap in Q-filter and L-filter ?

Re: Q filter What does it do, exactly?

feeds@yuku.com (lgbclp) — Wed, 18 Nov 2009 04:56:25 GMT

Sounds right from my understanding. If you want to retain more bass, increase the value of the resistor even more.

Q-Filter: How about sound if I change the value of cap from 0.1 to 0.2 uf and resistor from 5 kOhm to 25 kOhm ?
I used Q-filter with 0.2 uf and 25 kOhm, when I turned down tone to 0. Sound life acoustic, but I lost some volume and bass on lower strings. Is that ok ?

Someone could help me to know more ?
Thank you so much!

I'm curious to know what Q-filter sounds like. There is a clip with Keystones on a Tele, but I need more exposure. I'm wondering whether the filter known as MTC offered by Ritchie Blackmore's former tech Dawk and RBTC by some other company (to my understanding, it's an almost exact replica) is some sort of Q-filter? Here is a clip of RBTC on youtube, and the text on the clip pretty much explains what it does.

I always wondered how Blackmore got that wah effect when...

Here's a funny thing I noticed about my Q-tone installation. After rewiring my Parker Nitefly V1 guitar a few times, I discovered that I can hear a thump when I switch to the lead pickups (an L-200B and L-280B side by side with reversed polls on one). Incidentally, I have a 3 position switch to select either or both in parallel. It's a nice versatile setup. When height balanced together, it reminds me of an old Santana tone.

I think the problem is that the Q-tone is sitting...

I'm going to be rewiring my Strat type Parker guitar with a Q filter on a 500k Audio taper pot in parallel with a 500k tone knob. I wonder if it might be better to wire the "Q pot" so that most of the resistance occurs from 5 to 10 as opposed to 5 to 0, as is normally done. Anyone try this?

One can create schematics with an arbitrary number of components. The question is what you want to achieve. When you have specific questions, it's better to start a new thread.

Is there a way to toggle between the two different R values automatically as you roll the 5 way way? Is the old single cap tone totall obsolete now, or might a guy incorporate that somehow? If so any clever ideas? Also has anyone used a superswitch with BL pickups (preferably H/S/H)? If so a diagram would be killer, I'll post one when I get it doc'ed.

I'm sorry to hear that. Someone might be able to help you, but you'll probably have to start a new thread... most people don't check the stickied posts too often. Be sure to tell us what your setup is. I don't think using the filter without a cap and resistor is what you would want regardless, as it emulates lower output pickups in that configuration.

Hi Bill and Becky.

I have been wondering what the Q-filter does and if it works better with one type of pickup over another. I'm sure I'm not alone in this so I thought I would ask it here so your response can benefit others.

I'm always interested in improving my guitars, although it's hard to imagine my Nashville Tele sounding any better now that it has L-280's throughout.
