I always wanted a Dr. Boogey in a B-sized box, maybe with a 1 knob tone control
Actually, I've been thinking to make such a box too for a friend of mine. And maybe with a little less gain, as he's not so much into metal as I am ;)
But first I have to finish my MXR noise gate clone, which I need up and running in two weeks :-)

I'm struggling with this so far. But I'm tired from a long day.
I'll look again tomorrow night. I need to play with it .
It's screaming like a biatch so far but it's unbowed and I'll put a shielded wire on the output. I already did the input.
I can't get the 500k gain pot past 9 o'clock I'm a stubborn so and so. I'll have it fixed. I'm confident with a gaussmarkov pcb it will have the best layout possible.
Thanks again to my old buddy Dizzy for the loaded board. I can't thank you enough.
Report back later and thanks for the tips.

When I have a few hours spare I'll read through this whole thread too.

It's pretty high gain and I found it was relatively easy to get it to feed back (in a nice way).  I think this is intentional.  Will be quieter in the box.  I may have to build another: my first one was snapped up by yet another tame guitarist buddy.

Same hear last night when modding the box. Once outside the enclosure, I heard sounds unheard before :icon_eek: As soon as the box was closed again it was over.
I guess proper shielding is a must for this build (but isn't it always ;))

Thanks.  It's a waterslide decal on top of car paint, underneath acrylic clearcoat.  The graphics were worked up in PowerPoint of all things.  The "Boogie" part (complete with vegetation) was found on Google.

Have you had the opportunity to test this? My box does sound better with a different than 'standard' voltage (6.5v) on the second FET, but I haven't tried the other (yet)

So I'm curious what voltages work best for you.

imo its down to your ear at the end of the day..

when ive tuned up boogies i turn my guitar to its lowest point and get rid of any gating first...so it is at max open/release if you like,

then go from there...4.5v is a ballpark, but not a rule for these beasts.

That's why Boogey #2 will have trim pots (and a different tone stack   ;D)

i've had another go and i've stopped the whine, but i reckon when i get it boxed up i will be able to do a better job.

I'm building the second one now, but have to wait for the pots & dc plugs to arrive  :-\
This one will have the single pot tone control btw and trimmers for biasing iso fixed resistors.

heres how i set mine up (outside the box)
Q1    1.35v
Q2    7.89v
Q3    8.46v
Q4    5.26v


All this may change when i get it boxed
sounds great
