Hey Fellow Strat Heads-

I am looking to upgrade the innards of my Beautiful 2000 MiM Strat and I have been thinking about putting in some "Greasebucket" Circuits (or are they pots) . I tried some out at the local GC in a new HWY One and liked what they did to the tone.

Now I have been reading on TBX Pots and I was wondering if they were on in the same or are these two different parts. If So How Do They Differ?

Thanks in advance for all of your help.

no tbx isnt the same as the greasebucket. The tbx pot has a indent at the no'5 possition that is said to be the natural clear sound of the pickups whilst moving it up to 10 increases treble and presence, moving it from 5 to 0 increases bass. In truth the 5 possition is a strangled tone whilst 10 is nearer the clear tone, i removed mine after a few days and put a normal tone control in.
Im not too sure of the greasebucket but i think it keeps the sound balanced whilst reducing tone so you dont get a woofy bass sound. I could very well be wrong on that though.

The original American Standard series utilized the TBX tone control which had a noticeable detent at "5". The other tone knob was a standard tone control, not the Grease Bucket circuit found on the newer Highway1's.

Thank you Fellow Strat Heads-

Thanks for the insite. Is even possible to get After Market GreaseBucket Circuits? I havent seen them anywhere as of yet. Please let me know.

You don't need to buy and aftermarket one. You can make one with a couple of capacitors and your stock tone control.

See:

The basic idea is that you introduce the second cap as you turn down the control. Caps in series ruduce their overall value, so your changing the tone controls cutoff freqency as you turn down the tone control. This gives a much sharper cutoff and retains more mids.

I actually came up with this idea on my own before I knew it existed already (don't you love when that happens). My variation is a little more tone geeky and specific. I use two different types of caps because I like one kind in the 5-10 range (a jupitor paper and foil) and another in the 0-5 range (a Vitamin Q and yes I know both caps are involved from 0-5). It works really well, but you don't have to get that retarded about it.

eddie_bowers, I am curious if u have seen the high pass filter on the volume knob of the Satriani guitars?
Is that a similar approach to this technique or is it totally different?

No thats different. I haven't seen it on those guitars specifically, but i'm 90% sure that is to control the treble loss you typically get when rolling down the volume control. This is often called a Treble Bleed or Treble retention circuit.
Thats also good to have unless you like the less treble effect when you turn down (some do)

Just to be chatty on that point; I am one of those that does. If you "drive" the amp from the guitar's volume knob then that roll off of the treble as you turn down can be a useful asset. For instance, if you've set things up so's you have the amp just breaking at around six on the volume knob (so clean below that) then as you turn up the amp breaks into natural overdrive, getting nice and aggressive when you get to ten. What I find is that as that happens I also want more treble to keep the attack clear as the gain rises.

So instead of thinking of it as losing treble as you turn the volume down, turn the idea upside down and regard it as a way of aquiring treble as you turn up. So, no mods on the volume knob for me!

Anyway: a different way to look at it...

Cheers - C

Thanks for the reply.
Simply don't lift the volume pot engaging the high pass filter on the satch model.
