converting an axis fuzz for bass...?

[deadastronaut]

hi guys.

i found a vero for the axis fuzz...in the gallery by 'torchy'

i was wondering how i could change the input and output caps to best suit a bass..!..

also it needs to be a tip negative pedal.
.is the axis tip negative?..(no polarity issues...etc)

any ideas..i built the bazz fuss, but thats not as gainy as i would like...

cheers dudes rob.

I've heard people say to double them. I've used input and output caps as big as 4.7uf on bass. In some circuits, it won't make a huge difference, in some it makes quite a bit of difference. But you won't hurt anything by trying out different caps, so just try it out and see what you think.

Tip negative means that the center of the power jack is wired to ground. This has nothing to do with the type of circuit - it's something you can decide on your own, simply by wiring the ground to the tip tab on your power jack. Center negative is the Boss standard which most modern pedals follow.

You might be confusing this with positive ground. I haven't built one, but from the schematics I see, the Axis Fuzz is not a positive ground circuit so you don't need to make any special accommodations.

thanks taylor...

yep ive seen a lot of fuzzes that say they are positive ground...

and wanted to avoid that..great....

so would it mainly be the output cap that requires changing

to suit a bass?...

Well, kind of depends. When you send more bass into a fuzz, you fuzz the low end more, which in some circuits sound flabby or farty. Another way to adapt fuzzes to bass is ot add a clean blend like the B Blender. This allows you to have clean low end and fuzzed up mids and highs, which in some cases and to some people sounds better.

hmmmm..bit of experimenting to do then...

yes ive read about the blend control...makes sense...more usefull etc...

cheers taylor. rob.

You might try making  the input cap smaller.  Yes smaller.  Think about the Peak to peak output of a bass compared  to a guitar and other things.

The polarized cap attached to the *fuzz* pot has a huge effect on the sound
I tried a 100uf & got a fatter sound...but WAY too *splatty* for my taste.
Using a 10uf & smaller gets more touch sensitivity...but also into the treble boost dept.
Another area to play with.
