Grapevine - catalinbread dirty little secret

I just wanted to show a quick look at my grapevine before I paint it. I subbed a few parts values .033uF for .03uF. and it came out fine.

I was worried about the carbon comp resistors and stuff, but I just used what I had on hand and it sounds GREAT! not noisy at all.

I used a proskit enclosure becuase it's a little bigger than a 1590b and it gave me more breathing room to fit everything in.

I also got pretty crazy with my wire colors. I went with a rainbow theme across the top for the pots to keep everything organized. red, orange, yellow, green, blue, violet, white, grey, black.

Nice build!  Very clean wiring job.  Personally I like the various wire colors.  ;D

Velleman makes this kit of hook-up wire. I know alot of people prefer solid core, but stranded is better sometimes becuase it has less chance of breaking if you move it. I got this kit and I have made probably 15  pedals and I am not even close to half way through with the colors. They also give you MORE length on black and red because they are the most popular colors.

Here she is painted. I call her the GOLDEN SLAG. Which is also the nickname for my bands van which is painted a similar color.

I used TESTORS 1 coat lacquer in INCA GOLD. I used 3 coats baked in the toaster over 150 degrees for 30 minutes each coat. I was going to clear coat it but it looks good and I'm going to wait to figure out what to do for decals before I seal her up for good.

I also decided to switch to white knobs because it looked better than the black with this paint.

The sound is pretty good. I actually prefer it to my fulltone ocd. The only thing I don't like is the tone knob I only really like it cranked up or a little under cranked, other than that it sounds like a blanket. It is a really quiet pedal too compared to other dirt pedals I have. My rig is really noisy too (les paul with p-90's)

headline sign brand rub on letters. It was pretty lengthy process getting all the letters lined up. I put strips of masking tape for my baseline and tried to line up the letters the best that I could. a few letters broke so I filled them in with fine point sharpie. I can't even see the difference anymore.

several coats of high gloss polyurethane lacquer baked on to seal the letters in.

The gold box with the white/cream knobs looks really, really classy. Might need to emulate that for my honeybee clone.  ;D

I too dig the gold.  Were you happy with the testors paint.  They have some nice colors.  Also, did you prime it before the gold?

I am happy with the testors. I went with three coats and it got a little thick in places. I would recommend 2 coats only of this "1 coat" paint.

I did a coat, then 30 minutes in the toaster oven at 150ºF then a 10 minute cool down before the next coat.
3 layers of minwax polyurethane spray high gloss clear.

I did not use primer, I did sand the enclosure with 3 different grit of sand paper (a testors hobby sanding kit)

but since then I have found ALUMINUM OXIDE sanding sponges at an artists supply store. It is awesome for sanding enclosures. I got the medium/coarse grit, and then the fine grit sponges, they work really fast. Just clean up afterwards with dawn and water, then I clean again with acetone before painting. works great.

Hi there,

I was checking my DLS build on the great Brian's board against the one I did in a board i've designed, and I found a mistake on Madbean's. Mine was sounding like there was a blanket in the amp to, but now sounds VERY good, just like the real deal. The bright cap value is wrong, it isn't 100pF like shown in the schematic, but 151pF. When modding this, you can put a 5000pF cap in parallel with this one. That's the difference between Catalinbread's V1 and V2.

here is another enclosure I just finished with testors 1 coat lacquer. lime icehttp://www.testors.com/products/137180

process was this:
sand coarse aluminum oxide sponge
sand fine aluminum oxide sponge
wash with dawn rinse
wash with acetone, evaporates quickly

spray 1 coat of testors 1 coat lacquer
toaster oven 150ºF for 30 min
10 min cooldown
spray 2nd coat of testors 1 coat lacquer
toaster over 150ºF for 30 min

apply water slide decals (lazertran for lazer printers)
dry with towel and allow to air dry

apply minwax spray polyurethane high gloss http://www.minwax.com/products/interior_clear_protective_finishes/fast_drying_polyurethane.html

allow to dry for 30-60 minutes

apply 2nd and 3rd coats if needed.

I ordered another grapevine board so I will try this correction. does 151pf vs. 100pf make all that difference? 0.000151µF vs 0.0001µF. mine doesn't sound like there is a blanket over the amp, just when the tone knob is turned down.

I was also going to put the rawk/rock switch on a stomp switch with a 2nd LED for RAWK mode

Well, I'm using my tone knob around 12 o'clock and there's plenty of treble, no mudness at all. And I really think the 4700pF in parallel, as stated on freestomboxes by Nicholas, from catalinbread, is a veeery worthy mod.

BTW, that son of a ts looks just great!
