CertainBass Groov-a-Tone passive tone filter for electric bass guitar NEW!

They kill all the highs and mids. But there are applications not so extreme like the blues, gospel bassists who need to cut under a 100 voice choir, large Salsa, Afro-Cuban ensembles and the blues, especially the blues.  We like deep and organic, but sometimes i need the bright slap tone that will take the top of your head off, the Groov-a-tone has that, too, lower midrange dip with strong low and a metallic highs, in a couple of flavors.  Start knocking some of those metallic highs, and you're headed for dub style.  From Family Man to Marcus on a dime with Jamerson and Jaco lurking in between. 

First question you might have is "What exactly is a passive filter and why are they so great?"  First of all, it's old school  Back in the olden days, say you wanted to boost the low-end on your bass track, what we did is cut the highs and mid range then turn the track up.  That's how we added bass.  Passive filters only cut frequencies, they don't add.  Active systems add noise while passive systems are quiet and reduce noise while shaping your tone.  And passive systems are warmer, they just sound good while actives are often sterile or brittle.  The big kicker is no battery.  That's right, the Groov-a-tone is a green machine in that we're not littering batteries, but, most importantly, you don't have to buy them!

Groov-a-tone gives you many sounds including the most important ones:  yours. 

• Here's how it does all this.  There are two sections, a mid range section and a high end treble section. The top knob puts in a notch filter which is a midrange cut that's very deep but narrow. Adjusting this knob decides the center frequency of what you want to clean up as well as the character of the overall tone. You can see the center frequencies on the unit. Because the notch is deep, the middle knob decides how deep the notch goes. You can easily hone in on a sound then tweak the amount of change. All the way clockwise is bypass and all the counter clockwise is full cut. The in betweens are where the action is, and we experimented and found the optimum pot values for a nice, even sweep. The other section is the high end cut section   Same as the midrange cut section, all the way counterclockwise is full cut, but instead of taking out a slice like the mid section does, this rounds off the top in a nice gradual high end roll-off. The two switches decide how deep the roll-off goes while the bottom knob determines how much. The roll-off switches are a customizable feature, and it's good for A/B'ing different values of capacitors or different caps of the same value such as a poly film cap vs. paper in oil.  

Because they are made to order, we promise delivery within a week to ten days.  

I don't always groove, but when I do, I groove a tone.  Nah, not really, I always groove.  With Groov-a-tone, of course!

• I should mention too that the electronics inside the box are not new to us. We've been putting this and other systems in the basses we make for years.  What's new is the box design. This allows people to get their sound on all their basses without modifying any basses, and it's a nice occupant of the producer's brief case.

There is a video on our CertainBass Facebook page showing what the Groov-a-tone can do for you.  We'll try to post it here soon.

Here's what the Grammy-winning producer Mark Prentice has to say:

"Okay ... Buy this.  Trust me, just do it. I sorta hate revealing my secret weapons, but David's work is just too cool to keep to myself.  First, it's pocket change; I've had bigger bar tabs.  The vintage tones are incredible, spot on to the whole Jamerson, Duck, Rainey thing (the Grail, in my humble opinion) and the brighter tones are also awesome.  And dig, you can get right back to the tone you want, any time, every time.  This thing is made by a guy who's not only a smokin', seasoned pro player, but a superior builder and a true student and historian of the deeper electric bass story and tradition.  And as if that ain't enough, try it for 30 days and if you're not thrilled, he'll refund your money.  You can thank me later."

CertainBass is a maker of fine electric bass guitars.  4 string fretted and fretless Jazz and Precision style basses are our specialty, but we have branched out into 5 string Jazzes and some short scale basses.  We first developed our Varitone exclusively for our custom bass guitars.  We have developed the best Varitone circuit found anywhere with fat tones and silent switching not found in other Varitones.  We will also customize your Varitone circuit with an optional blend control so you can have a little or a lot, find the sweetspot and we can a high end roll off to take away metallic tone.   We provide a variety of wiring schemes for any passive bass.  

As a maker of custom basses, we get requests for models people want but others don't make allowing us to find holes in the market not being satisfied by anyone else.  

What accounts for our goodwill in the market place are my proprietary build techniques, excellent set-up of each bass and tailored, one-on-one customer service and communication. CertainBass is the only company (I know of) to have this guarantee, "You will love your new bass."  Whenever a customer plays any of our basses, they go "Wow!" usually within the first two bars. That's what sets CertainBass apart from others.
