Took a Gamble; Succeeded!

Unverified layouts are a gamble, especially if you're like me and haven't the slightest clue how to fix them if they happen to go wrong. I've built a few circuits from unverified layouts, ending up with mixed results. If you'll remember, last year I built a circuit that didn't quite work out from a layout that was removed entirely from the layout website. I'm assuming the builders of the pedal it was based on asked the site owner to do so, which I totally understand. The pedal is supposed to simulate Stevie Ray Vaughan's sound. What I ended up with sounds ok, but it has a few quirks I'm not sure how to fix. So, it stays as-is until I can figure it out.

This new one is called the Lovepedal Super Six "Stevie" (or SRV) Mod. I'm a fan of the blues, and I'm also a fan of Stevie Ray Vaughan, so why shouldn't I take a gamble on a layout for a circuit that helps me sound like him, again? Yeah, I guess it's an on-going theme that I'm wanting something that helps me sound like Stevie. More based in reality though, I'm finding the pedals that can get me a good SRV tone, such as the King Tone Blues Power that I built two years ago, are just generally good circuits for a nice blues tone. That's really what I'm after, and the more blues inspired circuits I can find, the more I'm going to build.

I guess this layout isn't entirely unverified, because in the forum where I found it there is one other person who claims to have built it. I've been burnt on layouts that were verified simply because one person claims to have built it. The copious amounts of fellow befuddled commenters below such layouts only serves to prove me right. If you Google it, as written above, and go to the images, it should be within the first row. Make sure you read the comments in the forum post below it for a few things, but let me assure you it is 100% verified.

When I added the Lovepedal Super Six onto my build roster last year I found a lot of questions about the "SRV Mod", which made me want that layout instead. Come to find out, it wasn't a mod at all, but rather a complete redesign. The Super Six is MOSFET based, while this uses a NE5532 op-amp. I was hoping it was simply a few parts swapped and voila, but no such luck. After building it I will say I'm glad the author of the layout put in the time and effort. I've not seen a schematic for the original pedal, but this circuit sounds good. There is another SRV inspired circuit I'll be putting together sometime this year. That layout has been verified for quite some time, so I'm not too worried. I'll just have to wait and see what it sounds like once I've built it.
