Nostalgia Is a Hell of a Drug!
Have you ever seen a 40-year-old man more gitty than a kid about to attend their first Taylor Swift concert? Well instead of getting raked over the coals by Ticketbastards all it took for me was a $13 investment in Castlevania 2: Simon's Quest. Castlevania 2 was one of the first video games I purchased all by myself, from a flea market in the 90s. I remember being allowed to freely roam the flea market when I happened upon a booth that had games for $5 each, to the best of my recollection. At this point I had never hear of, let alone played any of the Castlevania games, so I knew absolutely nothing about them, but the label of Castlevania 2 looked cool so I bought it.
I remember rushing to find my parents after I made my purchase and urging them to go home, as I wanted to play my game immediately. Youth, am I right!? That's not how my parents played it, so I had to continue walking around the flea market, now without any money, until they were ready to go home. When I did get home, however, I did all the cartridge blowing and whatnot to get the game going and was dropped into a world of my own making. I was confused. Without a manual I had no clue what I was supposed to do. This was well before Yahoo, Google, or even youtube tutorial videos. So to make the best of my purchase I just walked around killing the monsters, and that became the game's objective to me. I counted how many monsters I could kill before they killed me. That was Castlevania 2: Simon's Quest to my youth addled mind.
Along the way I've lost a lot of my old NES collection, mostly due to youth stupidity, and as an aging man I find myself wanting to collect them, just to have them again. Sure, I could play Simon's Quest on the NES Classic, or even better, an upgraded ROM hack on my modded Wii, but there's something very deeply connected to my memories about having the actual cartridge and holding a real NES controller in my hand while actually playing the game. You know as it was intended and not just as my ignorant childhood mind made it up to be. I'm really glad to finally have Simon's Quest back in my collection. And yes, I am playing it just like I did as a child; on a CRT through RF, and it's really not that bad. This completes my Castlevania Trilogy on the NES, but I have a few more cartridges I plan to track down. Maybe this will become a series. We'll see.

A Big One Down, Two to Go!
One guitar pedal I've wanted for a long time, or at least an adequate clone of, is a Boss HM-2. The problem being they stopped making them years before I even knew my first guitar chord. Sure, I could throw money at the problem, but you and I both know that's not what I do. This build has been almost three years in the making, seriously. I researched and researched and even watched almost every video about the HM-2 by Dome on youtube. As well as MANY videos by HM2CULT on youtube.
Most of the HM-2 layouts looked scary because they require three op-amps, which really put me off. Now, I did build four variants of Centaur clones, so you could catch me on a technicality here and say I should be able to build an HM-2, but I really wanted to make sure I was building the right one. The layout world is abounds with layouts for HM-2 clones, and finally I found one that I felt comfortable with. Not to give the game away, but this one only required two op-amps; a singular TL072 and a TL074, both of which I have.
After cutting the board and packing the parts I was excited that my dream was finally coming true, I will finally have an HM-2 clone and I'll be able to chainsaw the living hell out of whatever is left of my eardrums. HA! Too late, I don't have eardrums. No, seriously I was told by a doctor at the at of 15 that I have no eardrums. Protect your hearing kids! On a heavily overcast day I decided to take all my stuff outside and finally give the HM-2 clone a whirl, but I was going to do a few mods to the layout that I felt suited my needs.
Ok, the layout has switches for engaging the hard and/or soft clipping diodes individually, which I decided to replace with two jumpers instead. The layout also has a mids control, which I swapped out for an internal trimpot to keep the option, but not take away from the external HM-2 vibe. After a few frustrating hours of building, mostly due to my overcomplicating the process by wanted to build it my way, the circuit was ready to be tested. Welp, I wired in the volume control backwards. I also wired up the mids trimpot backwards, both of which are easy enough fixes. So, you want to know does it chainsaw!? Eh, well, uhm, not really. I don't know what's going on. It's a REALLY nice heavy metal distortion, and adding some mids with the trimpot makes it a little bit nicer, but it's not chainsawing to my ears.
My circuit seems to step right up to the line of chainsaw and stops as it stares longingly into the black abyss where all the other HM-2 clones are screaming and chainsawing away. I've checked all the gaps for solder bridges, I've made sure everything was where it's supposed to be and it all seems to be right, it just doesn't sound right. Again, it's a really nice heavy metal distortion, but Left Hand Path this is not. I'm sure it will find it's use, but I guess I might just plunk down the cash for the Behringer el cheapo clone since this one didn't work out the way I hoped it would.
All that being said I'm down to two build left; a Soldano SLO 100 emulating preamp and a Lightspeed overdrive clone. Yep! That's all I've got left. That will bring me up to 68 builds, as I believe I said in the last entry, so I need to come up with something spectacular for the 69th build. I just don't know what it could possibly be yet. Nothing planned, it's all up in the air, but believe me you'll know when it's all said and done.

New King on the Block
Once all was said and done I'm glad I used an external presence control on my Prince of Tone. With the internal presence adjusted and the clipping diode switched flipped, I chose to keep the yellow channel as an edge of breakup crunch/boost and the red channel I put on the hard clippers and let it ride. I did swap out the normal gain control on the red channel for a 250k. Whether that's actually how the "high gain mod" works or not, I don't know. It doesn't matter as what's done is done. The red channel gets really heavy distortion, especially when I hit it with the yellow channel.

Pedal Experiment 64
Sometimes I feel overwhelmed with a pedal build. Whether it be the number of components, or jumpers that I have to install, I tend to put it off for as long as I can until it can no longer be put off. With only three pedals left to build I did what I always do when I feel overwhelmed, I decided to throw something else together. Completely unplanned and spur of the moment I went through the layout websites and searched high and low until I finally found something I could put together quickly. Sometimes you just need that fresh shot of success juice to give you the confidence to take on that which overwhelms you.
Since I'm all out of new stripboard I had to rummage through my scraps, but I did find a piece just big enough. All the resistors I had in stock, but when it came to capacitors I did use 150nf instead of the required 100nf, just to experiment. For potentiometers I used some experimental ones I had laying around with parallel resistors to adjust their values to suit the needs of other builds, when I didn't have the required value for those builds. For clipping diodes, well I decided four 1N5817s should do the trick. It only requires three for clipping, the fourth was polarity protection. And then the build required two transistors. Stock requirements are two MPSA 18s, of which I do not have. I went through my parts and found the highest gain little bastards I could find and those just so happened to be some reclaimed C1740s, they'll do!
Even though I already built one of these circuits earlier this year, I used a different layout and a completely different component set this time. I can't currently A/B them so I'm not sure how much of a difference the part selection has made, but I can say that this circuit sounds pretty good. I know I say that about almost everything I build, so take that for what it is. However, this circuit sounds similar to an op-amp overdrive even though it's just two transistors. That might be a clue as to what I built, because I'm pretty sure I said the same thing about the previous one I built. One of my initial concerns was the amount of bass due to the higher cap values, but after running this pedal through Kali (who is VERY sensitive to bass) I feel confident the amount of bass these caps might have added isn't going to overpower the ability for it to be removed somewhere else in the signal chain.
All things considered I'm impressed with the fact I can throw together a random selection of parts and get these results. Granted, this circuit was already known to work and sound good, but with my throwing things together that just felt so completely out of spec with what the original circuit calls for I was braced for complete and utter disaster. Since this is my 64th project build I named it Experiment 64. When I get the chance to A/B it with the stock version I will, but to my recollection I don't remember it being much different. Obviously I'm pretty sure there are going to be differences, and I still expect there to be a touch more bass, but which one sounds best, if they sound much different at all, remains to be seen.

Repeating Myself: Delay Pedal Build
One thing I said earlier this year, perhaps a few times, was that I wanted to step away from drive pedal builds and work on more things like reverb, delay and other styles of effects. While I have worked on other effects: two reverbs, two compressors, one tremolo, a few LM386 based power amps, an envelope filter and two inductorless Wahs, I somehow totally forgot to add a delay pedal to my list of builds for the year. My Disaster Transport Jr. clone has a bit of background noise that I need to address, but I love it. My super cheap ($8) Mugig Echooos delay pedal has been really awesome too, but something echoed (get it!?) in my head that I still need another delay pedal. Maybe more, but for now at least one more.
I still have a ton of resistors, transistors and capacitors, but potentiometers are starting to dry up, especially now that I can't put together quick orders from Tayda Electronics. I love you Tayda, but $20 shipping for $5 worth of parts just doesn't make sense. I know it's not your fault, I forgive you, I just hope one day soon I can order from you again. All that being said I need to check my potentiometer stock before I add anything to the build list, most of which gets kicked off due to the lack of one singular potentiometer. Oh, I know I can adjust the value of a potentiometer, but I prefer not to, because it doesn't always yield the correct results. This paragraph was a long way around in saying potentiometers are limiting my options for delay circuit builds.
Then it happened! I saw the layout for the Wampler Faux Analog Echo, and it was glorious! There was a problem though. I didn't have the 50k linear pots for the delay and level. Sooooooooo, I used 100k instead! What happened? It seems I might have a bit more delay time, and the level seems to get a bit cripsy on the very top end, so just don't crank the level all the way and that won't be an issue. Once it was built I tried to adjust the settings to the ones suggested in the manual for the real pedal and I wasn't far off. All the things the original pedal can do are in here, it just takes a little adjusting to find them. No problem.
With the Faux Analog Echo finished that makes my sixty-third completed build, twenty-ninth of the year and that leaves four projects left to build. I'm not saying I won't add more, it's just that's all I've got currently. Sadly I've procrastinated on some builds because they seem complex and I'm not wanting to screw them up, so I figured I better screw them up last, you know? Hopefully that's not the case, but trust me, you'll know if I do. Or will you? Maybe, maybe not. Let's just all agree that the remaining builds will go well, and everything will be fine by the end of the build year. That's the spirit!
