Tech Help - Etcher's Paradise / Aquaboy-BL - Verified
« on: January 01, 2017, 01:34:02 PM »
I've been on a bit of a building bender lately.  I can't help myself!  Just finished up the Aquaboy. 

The ghost switch does not seem to work though so I removed it.  I couldn't hear any difference with the switch on or off.

I accidentally used 0.1 uf electro caps instead of 1 uf, but caught the mistake before putting on the pots.  I had a bit of an accident removing the old caps and one of the traces lifted off the board right at the hole, but I was able to correct it by soldering the lead onto the trace. 

Here are some pics of the board, with a strange assortment of knobs I just used for biasing it.  I still need to tweak T1 a bit more to dial in the self oscillation which it kinda a fun feature bringing the delay into oscillation and then messing with the delay knob to bring it into complete mayhem.  Gonna have to box this guy up.


Build Reports / Deadringer Jr. - Etcher's Paradise

Finally got around to boxing this thing.  I ended up not using the flats switch.  The etch image is stolen from Ironfire Brewing Company's Six Killer Stout, an amazingly good beer and a great brewery.

For some reason boxing this up was causing me so many problems today.  Wires were burning, then I realized my solder iron was too hot must have bump the stupid little temp wheel on it, which I do all the time.  Then I had a bad switch, then I had the clipping switch the wrong way.  Oh well, its good experience right?  The rest of the build was really smooth, especially etching the pcb and drilling the holes.

I like this pedal a lot.  It's going on my pedal board for sure.  I like that its a smaller version of the Fulldrive and gives me exactly what I need.  I love the way single coils sound through this thing, it really lets them shine through so you can totally hear you are playing a single coil.

All in all great pedal.  Totally loving the Etcher's paradise projects.

Finally got around to building this and it is verified.  I didn't have a right angle pcb mount 20KW, so I used a solder lug one, and I think I might just use solder lug pots on etched pcbs from now on.  I accidentally damaged the connection of lugs 2 and 3 on the drive pot so I had to make an extra connection with a jumper.  I think the nice thing about using solder lug pots on these is you have a bit more leeway to move the pots around after the fact, where with the right angle pots you can easily lift the copper right off the board. 

Sounds great I'll have to box it up soon.  Ignore the extra little wire piece near c3.  To lazy to take another picture ;)  Thanks for the layout.

Build Reports / Crazy Tubes Ziggy

Built a Crazy Tubes Ziggy Overdrive from Perf and PCB Effects Layouts

If you haven't checked out the site you should totally do so, some great layouts on there and drill templates.  Thank you for a great site.

I'm super impressed with this community, so many people willing to share knowledge and experience.  Gotta throw a shout out to Madbean too for all the work he has done to educate and provide resources to people.

I etched the enclosure using some tips and tricks from this site, thanks to all those who posted all the great tips and special thanks to m-Kresol for saving my lungs and health by switching me over to ferric chloride for etching.  I have found that you can get so much more control and quality out of the etches. 

Alright enough of the love.

Had a little bit of trouble with the pcb only because there was a little bit of solder that overflowed to ground and it took me a while to figure that out.  But... this pedal sounds great!  The gain and tone controls are really usable and I can get some really cool sounds.  And, you can totally dial in that Ziggy Stardust sound if you want to, which was the inspiration for the etch.   

Build Reports / Cosmopolitan - AKA The Beefeater
« on: October 07, 2016, 06:04:37 PM »
Finished off my Cosmopolitan build using the layout from the Etchers Paradise.  Etching both PCB and enclosures is still new to me.  Those of you who etch, any tips on how you get the enclosures so clean?  I used a combo of hydrogen peroxide and muriatic acid.  Maybe its just too strong of a solution, it always eats through my transfer and my Dykem Action marker.  For the PCB I used sodium persulfate.  Would this work on enclosures too?  The acid is pretty fun just because it sizzles so much.

Anyway, this pedal sounds awesome, I think everything that Skreddy makes is rad.  I love that this gets really fuzzy, but also serves a really nice overdrive. 

Here it is:

Build Reports / Rabbit Hole / P19 1/2

Here is my Rabbit Hole build.  It's a Skreddy P19 clone, but tiny... hence the 1/2.  I prefer the Mid Hump, so its hardwired in.  Text is using my cheap-o Brother Label Maker, which works but sometimes is noticeable depending on the light.  Sounds pretty great.   


Tech Help - Projects Page / Too much delay on Glam Chorus
« on: April 04, 2016, 06:06:34 PM »
Hi Everyone,

I've build the Glam Chorus and it seems to be sounding more like a slapback than a chorus, too much delay.  I heard an audio sample of it on You Tube and it sounds great.  Mine though has just a touch too much delay.  I double checked the values of everything and it doesn't look like I put in any incorrect components.  I tried a different PT chip and got the same results.  Anyone else have a similar problem?  I don't really know much about this circuit, is there a way to reduce the delay time on it?  I checked the voltages compared to whats in the build doc and mine are a bit, are higher by almost a volt.  Is this just a result of a power supply that's giving just a bit too much juice and increases the delay time?

Thanks for the help and info that you can provide.
