It appears everything will be fine  :D

How long does it take you to make each unit?

p.s. looking good!  8)

my wife would tell you it is the only thing i have been doing for the last two weeks.

now that i have a design, and make 4 at a time i think i can do them in 8 to 10 hours (2 to 2.5 hrs for each box)

of course it acutally takes a few days waiting for paint to dry and all.

I am going to start having my boards made, so that will speed it up a lot.

Brian

Looks cool! 8)  I wish you the best of luck with your new endeavor. I've heard good things on other forums.

By the way, I like the halo of spray paint on the inside of the bottom. I get the same thing on my DIYs when I prop them up on a plastic cup for their transformation from bare aluminum to painted glory! Rock on!

yeah, i cleaned out the aluminum arround tha jacks and pots, but i didint clean the bottoms up.  I sort of like writnig all the stuff in the middle of it.

brian

I do the same thing. Great minds think alike, huh? :wink:

Funny, the family didn't look 'concerned'...

hahahaha

just having a battery put in.  routine stuff really.

1 opamp
5 resistiors
3 pots
1 led
1 battery
2 diodes
4 caps
and a bunch of wire, and a lot of TLC.

Are those 630v metallized polyester caps?  I've noticed them in alot of people's pedals...is there something wrong with the green 100v ones?

i used the 630 volt ones cause i got the dirt cheap.  but thats me..  i mean if you can get a closeout deal on a big lot of capacitors for next to nothing. i got soehting like 1 cent caps.

Ahh, good point.

Sorry for the cliche, but that looks like a REAL fuzz face, Brian! (yeah, I know :lol: )
In all seriousness though, it looks great.
For what its worth, I wish you every sucess (but dont ignore the wife too much though- I have seen first hand what angry women can do to stompboxes...) :D
Congrats again Brian
Take care,
Cheers,
Luke

It seems that females and stompboxes don't mix ;) My girlfriend is also complaining that I should marry my pedals instead of her  :oops:

Brian-

Did you say you were silk screening the enclosures?
If so, what kind of setup are you using?  Also, what
kind of ink?

thanks-
-alan

right now i am just using the speedball starter kit.  The ink is standard fabric ink, but i give it 20 minutes to dry under a hot lamp, and then clear coat over it twice.

i bought some solvent based ink and solvent resistant emulsion, but need to get a new screen to set it up, and really need to build a good work station for it.  i still need some solvent for it too, because the solvent based ink will not come out of the screen with water.

Brian

When you say "standard fabric ink", do you mean Plastisol? :shock:

I wouldn't use anything other than ink made for signboards for the reliability aspect. Any decent ink should not require a clear-coat to be VERY durable.

For solvent, the best seems to be xylene. You can wash out a screen with xylene many times without damaging the stencil at all.

Take care,
-Peter

Thanks Brian!  I picked up the speedball starter kit, but I haven't
tried it on an enclosure yet.  I was wondering if I needed to order
some of the Nazdar ink first.  It looks like you got great results
with just the standard stuff, so I'll give that a try and see how it
goes.

-alan

that's what i bought nazdar.  i saw it on a previous post a while ago and wrote it down.  Still havent used it though.

I just want to thank Brian for posting the Stupid Box. I put one on perf last night and it rocks! It's like a full range Tube Screamer without all that ridiculous midrange. Also; more gain on hand, I used 2 Ge diodes and 1 1N4001 for some crunch and assymetrical clipping. One other slightly different thing was I used a LM741 I had which worked fine.

Thanks again

RDV

cool.  thanks for the review.  

i was thinking about switching to a single op amps instead of the duals, but i have about 100 tl072's.

The design was actually inspired by the tube screamer.  that was sort of my starting point.  I like the swept filter for the tone control.  i dont understand why more pedals dont use this.  it makes it a lot easier to match the pedal to an amp.

i put up some sound clips at
http://subdecay.com

Have you thought about using the second stage of the opamp to do a 2nd stage with diodes to ground like a Dist+ and blend between the 2, or better yet, footswitch between them for dual OD kind of like the Wayhuge Cameltoe.

Just a slightly inebriated thought

RDV

I've done lots of things with it in my garage,  I was thinking about building one with about 7 knobs with an active filter bias control, and a boost switch, and even an LFO on the input bias voltage.  I tried doing it on bread board, but i couldnt get it to fit.  a lot of off board wiring on bread board is a pain in the ass too.  I actually ended up building a different circuit when i got mad and ripped all the parts out.

i might post that one soon too.  not really perfected yet

I only suggested the second stage because you were using a dual OA in the SB so to incorporate the 2nd OA stage wouldn't require much more wiring really, since you already have your Vr and V+ handy. I may try the Dual Overdrive thing myself and post a report when I get it done. Waiting for parts, you know.

Regards

RDV

That's cool, there's lots of things you can do with it, but i posted it the way i thought it sounded best.

I tried a few different opamps, tone controls, diodes.  asymetrical clipping, hard clipping, and many others.  It is a farily simple circuit and easy to have some fun with.

My little plan entails having one side being your design exactly, the other being a diode to ground after output the second side of the Dual OA like a Dist+ and having two 3PDT switches to turn them each on or off or have them cascaded. Sort of like a Stupid Dupid 2N1. Just for shits & giggles. I just do this stuff to occupy a sick mind. People around here just stare at me when I tell them that I do it, almost as if I'm telling them about masterbating or something.

Somebody will definately know more about this than me, but I wonder why you'd need the extra opamp if you really just want to add a diode clip to ground section.  You can do that after the first opamp.  On the other hand, I suppose it would be handy to control the gain before such a section, so the whole MXR D+ thing might be handy.  Someone who has built such a beast would know whether you get useful interaction between these two different types of clippers.  To me, diodes to ground (eg D+)sound a lot harder and crunchier than feedback diodes (eg TS), and it's hard to imagine the former not overwhelming the latter.  Comments??

my guess is he wants two seperate circuits so it would be like two channels.  if you have the loop clipping on, and then turn on the ground clipping it you will lose some volume for sure.  It makes sense to me.

I like the nazdar inks, i just hate the cleanup involved with solvent inks.  Stinks up the whole house.  

The speedball ones chip and scrape off easily but i never thought to clear coat over them... good idea!  Get the speedball silver acrylic ink, it's bad ass!!  looks great on black, red, navy blue paint jobs.

I would have the feedback loop clipper first in line so when you use both the mellower FB loop clipper would have a somewhat mellowing effect on the diode to ground clipper. Of course you would also have the option of turning them on or off seperately with a 3PDT for each(wired like a Z.Vex SuperDuper2N1)

If you do it right, it would be a really cool versitile pedal.  you might want to actually reduce the gain, by using a smaller cap to ground the feedback loop on the first stage.  it would reduce gain on the lower frequncies, and allow you to overdrive the 2nd stage without getting muddy.
