Dr Boogey tonestack

[served]

Hi!

I know it has been discussed here before many times.

But I cant find the right spot. And what makes ma mad is that I cant get any info from geocities.com page. I built the Dr a while ago, but i don't have any documentation restored.
Could some one borrow me the schematic of the original tonestack of Dr Boogey!
I would be very very happy!

The original tonestack will be the same as the one in the Mesa Rectifier amps, on the lead channel. Schematics for Dual Rectifiers can easily be found through Google.

So you are saying that Mesa Solohead uses the same Tonestack as Dr Boogey? I mean the Dr Boogey http://gaussmarkov.net/wordpress/circuits/dr-boogey/
I Have exactly the one, but my tonestack is changed abit.

As anchovie said, the original tone stack is pretty much the same as the one found in the amp. IIRC, some values were changed to accommodate what was more readily available to us DIY'ers (ex. 250K pot instead of 220K). Then somewhere along the line, someone suggested to scale down the tone stack. I can't remember why but I think it was to minimize level loses. Anyway, the DRB tone stack now is the scaled version of the one found in the amp.

Here, compare the tone stacks in these schematics:

Thanks! I am building my second dr Boo now. I am hoping to make it better. No actually i will spend more money on it, better components and so on, and then I hope to see some improvements, but well see.

I just incorperated the BSIAB2 tone knob to my Dr. Boo and it works just fine.  No hassles just turn the one knob and jam.

sorry to hijack the topic m8s, but I like this idea, I "hate" fxs with more than 3 knobs (my drill skills are terrible!!!  )

.....so you just connect Q5S/R13 on gauss schematic

to the positive side of C9 on GGG schematic ?

and that's it ?

I love how my BSIAB2 sounds

Well i thoght what the hell, ill try this one also. But I think it needs some calculations? Doesnt it? Muffs tone differes from BSIAB2 the input is different, so I guess that Boogeys tonestack should be different also. I know that there is a tonestack calculator, but I havnt learned how to use it so thats why im actually sitting here and asking theese stupid questions. I guess i should do something about it.

And when I want 3-band tonestack? Will the original from gaussmarkov.net work fine?

[served]

Yes! It works pretty well. I have been playing with the original couple of months, and its good.

And now for something completely different...
Dr Boogey utilizes a Marshall style 3 knob tone stack. Anybody tried replacing it with a Fender one?
