Low-pass filter in a pedal?

Hey guys-

I'm looking for essentially a tone knob in a pedal, as I dont have one in my guitar and I'm not really interested in putting any holes in it.

It could be a regular on/off pedal, or it could be a rocker pedal that varies the cutoff frequency.

Anyone seen anything like this?

it'll do what you want it to do. Just need to learn how to use it.

Never seen one, but it would be cheap & easy to build.

Yup, sure would, Rich. I'd probably build a small buffer in with it too just to keep the signal strong, probably before the tone pot too.

Good suggestion. It works well as a light overdrive also. Other than that, any equalizer would work, whether it is graphic or parametric, and regardless if it is marketed for guitar, bass, or acoustic. The tones can be set, and they the unit gets switched on and off. If you are interested, the Boss EQ-20 has 9 memory patches.

Thanks for the suggestions so far!

I thought about an eq pedal, it would basically do what i want, but its not really a filter. I found a Moog Lo-pass pedal, but it also has some sort of envelope on it that I'm not interested in at all, making the $250 price tag a bit high...

Also I think the idea of a rocker pedal to control the frequency cutoff could be really cool.

Anyone have any resources for building pedals?

An EQ pedal is precisely a filter. But so are rocker wah pedals, which would be another option. Also, check out the Dunlop Q Zone and other Q-series processors. They are also filters which let you adjust the size and shape of your tone, functioning similarly to parametric equalizers.

Guys, a wah isn't a low pass. In EQ terms, it's more accurate to describe a wah as a band pass. Sure, when the pedal's all the way back it's effectively a low pass, but moving the pedal isn't the same as turning down the tone knob on a guitar. Turning the tone knob down increases the amount of signal that goes through the low pass cap in the guitar. Pulling the wah back actually moves the frequency band that the wah lets through down to the low range.

If a wah was a passive low pass, they would be a lot cheaper, that's for sure.

I've never seen a pedal that was specifically designed to be a low pass, but you could use a graph EQ to achieve a similar effect for sure. Also, like others have said, it would be ridiculously simple and cheap to build one yourself with a small amount of electronics know-how.

He said to remove the wah guts. Then you could wire the pot up with a cap to make it a tone control.

DIY get a switch a pot two jacks a cap and some wire....
something like this with a additional cap
