Built In Distortion For Bass

[InFlame00]

Hello. I've got an Ibanez GSR200...the electrics (the active EQ) brooke down so I had the whole thing removed.
The bass right now only got an ordinary setup, 2 reactive pick ups, 1 tone and 2 volume.
As I'm left with a hole in the body where the pot for the EQ was i'm now thinking about putting just a regular switch (on/off) in the hole.
The switch is planned to controll a basic groundshaking distortion, doesn't have to sound supergreat aslong as it's brutal as @#$% .
My question is, how can I creat a simple distortion unit, controlled with just a on/off switch.
When the switch is in the Off-mode I wan't the bass to function just as a regular bass.

I've got a "cave" where the battery for the old EQ was so the power supply for the distunit won't be hard to fix.
Basicly I just need a partslist and a wiring diagram for a bass-distortion unit.

The Bazz Fuss can be pretty awesome on bass, is small and only needs an on / off switch (make other controls trimpots).

Where can I find a diagram for that then?

Bazz fuss at www.home-wrecker.com
Great sounding fuzz!! you could make a blend pot to blend the clean signal with the distorted. that would be cool.
My bazz fuss have no controllls at all. It's either on or of. Soundclipp here www.syndromet.com/sounds/fuzztration.mp3

Ok, looks like it's worth a try...when you're not using the last pot...shall I put another resitance instead for the pot or shall I just let it be and go directly from the last cap into the outoput?

Nice clip; love those square waves in my winamp window

[InFlame00]

Hehe, i sounded like shit. I won't build somthing inside the bass, from now I'll just stick to pedals

Are there any pedals you can recomend for bassguitars? (that I can build on my own ofcourse)

[InFlame00]

Hehehe, my amp died right now because of the bazz fuss. Can't play anything through it anymore.

[Bernardduur]

Wow....... (happened to me once too!!)

I can highly recommend the ROG Flipster; I am in love with that pedal.

Or a modded BIg Muff

[InFlame00]

Where can I find the schematics for thoose then?
a Big Muff modded in what way?
Do you play bass through 'em?

[Bernardduur]

Yep, I am a bass player; see my pedalboard on some other thread here on bass playing......

Schematic for the Flipster is on Run Off Groove.

My Big Muff I use for bass:
- Removed first pair of diodes.
- Replaced the 3.9nF cap with a 100nF cap.

[InFlame00]

Ok, what changes in sound will removing the first pair of diods do?
What schematic did you use for your big muff? I can't find any 3.9nF cap in this one http://www.montagar.com/~patj/bigmufpi.gif

And btw, have you got any soundclip from your BM?

[Seljer]

3.9nF = 4nF one next to the tone control in the one you posted

there have been many many variations among the different models of BMPs

[InFlame00]

Ok, I start to bleave that too
What version of the BM shall I go for then? Are there any other version of the schematic than the one I posted that are better for bassguitars?

[Bernardduur]

I tried a lot of different Muffs........... NYC, Green, Black, Triangle etc.....

The best is the Black or the Green Russian Big Muff.... I don't know why but I just like the tone of this one..... and with the mid-boost every Big Muff sounds great!

[InFlame00]

Aren't there any scheme for the perfekt bass BM?

[Bernardduur]

No






I should go with a Russian Muff with the first pair of diodes lifted and a mid boost; worked for me........

I also like the Acoustic Fuzz (from the Acoustic 360 heads)..... am trying to get one to work right now

[InFlame00]

I don't want to buy any BM, because no musicstore around here got one in...I have to build it from scratch...I don't wanna be a pain in the ass but if you check the link some posts ago...what shall be done to that scheme to make it work good enought for a simple thrashing bassplayer like me?

[Bernardduur]

This schematic + remove first two diodes and replace 3.9nF with 100nF cap (or a bit less; 100nF give a huge mid boost I love)

[InFlame00]

Alright! Thanku very much!

Shall I use the 1N914? And shall I follow the recomendations for the caps at the bottom of the picture?
And what diods do you recomend?
