LO - FI

[Kurdt_01]

Can someone please post a link for a schematic for a LO - FI pedal (pref not to hard to build)

Thanks

Dave

I think there's one at Tim Escobedo's site, sortof makes you guitar sound like it's being played through a phone. I find it a very cool effect for vocals: http://www.geocities.com/tpe123/folkurban/fuzz/snippets.html#lofomofo

Check that out.

See also the lo-fi pedal at geofex. It includes the telephone filtering as well as noise to add in.

Hi.  Tim E's LoFoMoFo certainly gives very Lo Fi.  Partly because the input cap filters LOTS of bass.  I found the sound too thin for my liking.  But with a change of the input cap (from memory I think 220uF to 2n2??) it sounded great.  Kinda medium fidelity.  

cheers

if i remember correctly that schem doesn't work.

To make it work, the wiper of the PANNER pot needs to be connected to Vb rather than ground. No big deal.

Don't see a voltage source on the schem...Vb is just 4.5V right?  can I just divide down using resistors?

[smoguzbenjamin]

2 10k resistors should work fine as a voltage divider.

I used the typical two-resistor-and-a-cap voltage divider, as Benjamin suggested, making 'Vb' 4.5V.

Also, I used the noise source from http://www.paia.com/drumtone.gif (transistor and op-amp in the bottom left hand corner) in place of the two-transistor noise source specified. This was pointed out by Tim Escobedo. The difference, as far as I could tell, just made louder noise (which I preferred), and can be done other ways I'm sure..
