Re: Paul Cochrane - Fat Bastard [documentation]

Of course there's tons of things that can be done to it. For one that input buffer isn't really all that great. At the time i was in a kick to get rid of as many series caps as i could. Yeah, i see the "get rid of as many series caps as possible" and i think i prefer that no input couplin...

Re: BAJA Optical Limiter revisited - rev2 [documentation]

The solution was to replace the polarity protection diode with a 100 ohm resistor and decouple the output side with a 220uf electrolytic to ground Just corious.. couldn't it be fixed just adding the 220uF decoupling after the diode instead of having to remove the diode? Would the diode works as a r...

That makes sense RE the 10k in parallel with the volume. I was wondering why they just didn't use a 10k pot
This it only lower the impedance right? But it STILL can have almost 100Kohms in SERIES with the output when vol pot near minimun...?? :roll:

I think so, maybe the posted schematic isn't really accurate, even if it's very close may not be exactly the real circuit.

I just wonder about that.

A 1M pulldown R will drop the value of a 250k git-vol pot to app. 200k, a 10M decreases the actual pot value about 4%. Furthermore a pulldown R has a big influence on the RC-combination of the guitar tone circuit which is even more worse. Sorry but this is absolutely mojo-nonsense..... At the time ...

The OCD++ is "my personal version" of the OCD wiith some minor mods and refinaments added, nothing more. I prototyped all 3 versions of the original and this circuits suits me best. :roll: So... where's the true OCD schem? Why we can't have a look at it? Thanks anyway for showing us your ...

Would be too much asking for a schem? An OCD verified schem?

If possible, thank in advance! 8)

Yes I think it's so good on LOW drive settings... one of the most I've liked for these purpose. low-gain 8) It's very musical and dinamic IMO :wink:

Thank you Morecowbell, thats good to hear from someone that had previosly tried that.
That's the good thing: We always keep on searching ways to improve tone 8)

Hello Kagaxdx The 2M2 resistor would roll off a lot of the high frequency buzz or scratchyness in this circuit. Cheers bajaman ps: a well known high end HiFi stereo amplifier manufacturer used to connect a 75K ohm resistor in series with the CD input socket (one each channel of course) in his top e...

IMO it's an interesting circuit in some aspects... That output, is using 2M2 :shock: in series with a 500K :shock: vol pot... :? But then lowering impedance before this there's a 47K to gnd. I'd like to know why? I know it could be achieved similar results with like a 47K in series with a 10K vol po...

How would you guys compare the TLC2262 ? :wink:

I think I like it, every circuit I tried it I liked the tone.
Soundwise how would you compare it with the others? I've never made such comparison...

Hmmm....I can´t imagine a big sound-difference between the 3 input-caps. And I can´t follow which influence the tone poti should have..... we have 11,5 µ output-coupling capacitor followed by a resistor of 50k to 100k. This neither influences the bass response nor the treble response I agree and I ...
