Title: Doppelganger
Post by: TNblueshawk on April 12, 2016, 07:41:25 PM
Funny how you don't build a pedal in about a year and come back and forget how to do decals right. Shitty decal work but I wasn't about to strip it. Anyhoo......thanks to Ian for a great pedal.

Nice work, John.  Whether it's a day or a year I've just gotten to the point that I hate decals.  Especially waterslides.

Looks awesome! Any idea if the response from the LED/LDR sets are different when angled? I see them lots of different ways (straight on, angled, heat shrinked, etc..).

I would imagine that's the brightest part, or it seems to be when you look down and get blinded by it anyway.

Awesome build !
I had a Doppelganger V2 but eventually sold it, unfortunately.

I'm afraid I don't. I just tried to mate the 2 and figured no light will get lost if they are kissing cousins.

Thanks Mark. I hear you on th decals. I've gotten used to them. I just forgot that for white backed water slides you have to cut the decal a tad short of the measurement of your enclosure becuase due to the thickness it won't roll over the edge a bit. It curled on me. The clear ones no problem. Stuff like that you just forget at our....er...my age  ;D

Thanks Cort.

Say maybe a dirt pedal would match with Joe better  ;D 

When I first started building I tried to match the pedal somewhat with the artist but I gave up after pedal 70. I just pick who I love and slap them on there. BB King would flip over in his grave if he knew I put him on an envelope filter  :o Albert King would crawl out of his grave and kick my ass if he knew I put him on a pedal too!
Title: What's going on with the resistors at R40?

Hi,
I'm about to build one of these. What's going on with the resistors at R40? I haven't read over the docs yet, but that looks unusual. Is that a mod? If so, what's it do?
Thanks a lot and your pedal looks great,
Brad

Brad, that's just me stringing together the exact value with a resistor teepee trying to get 91k. A little OCD I know.

For what its worth there is no good reason to not just have the LED facing directly to the LDR, assuming you use the prescribed values

thanks
