The Screaming Pumpkin (TS808 Clone)

What started off as a Bazz Fuss build turned into a pair of LPB-1 clone builds, which has now turned into a TS808 clone build. I had finished the LPB-1 clones maybe a month prior and had no clue what I was going to build next. I still haven't perfected a Bazz Fuss, maybe never will, but I was looking for something new and maybe a bit more challenging to build.

The idea came to me while I was tearing down an old radio and found an NEC c4558c op-amp. I know the 4558 is mostly associated with the Maxon/Ibanez Tube Screamer, so I decided to google NEC c4558c to see whether it was the same or something completely different. Very few google results showed much connection between the NEC op-amp and the TS808, but the few that did yield something seem to indicate some TS808 units do have an NEC 4558 inside of them, and they seem to be fairly rare.

Now that I knew I could build a clone around this op-amp I set to work harvesting the parts from the radio to go around the op-amp. It's just a simple fact that parts degrade with use and time, so I figured if I wanted a vintage TS808 sound I should use the parts this op-amp was already familiar with. I would say I accomplished that for about 90% of the build overall. The other parts I got from other various boards I have laying around.

Gutshot: She isn't pretty.
The layout I used came from Bitsbox.co.uk and their TS808 clone. I used slightly different transistors, so I can't say this is exactly like their kit, but it's probably fairly close. As I was far more comfortable with the Bazz Fuss or LBP-1 layouts I agonized over this build and took my time to make sure I got it right. I took a week carefully looking over boards I have to find the parts I needed to build this pedal, and another week doing things one step at a time to check, recheck, triple check and quadruple check everything to make sure I wasn't going to blow the op-amp once I put it into the sockets.

The day had come, I had finished the board and all that needed done was wiring everything up. I tend to enjoy wiring as I find it the simplest part of the build. The board was all together, the components were all installed inside the housing and all I needed to to was tin connections, tin some wire and solder things together. Even though it's usually a more relaxing experience this build almost broke me. I was so nervous about what could go wrong and trying to troubleshoot so many parts. I pressed on and soldered all the wires to where they needed to go.

I finished soldering up a ground wire for the housing and went to plug the pedal in and see whether it burst into flames or made some tubes scream. At first everything was working perfectly fine, until I engaged the pedal and go no sound at all. I was a bit disappointed, until I remembered that particular power supply has a short near the wall part. After fiddling with the adapter I finally got it to work. I twisted the knobs to see whether I had installed them correctly and the only problem I found was the tone was wired in backwards. Oops. A quick trip to the soldering station and swapping two wires remedied that.

Just to see if it made noise I tested it through my Fender Mustang Mini, but soon graduated to my Kalamazoo. The problem with the Kalamazoo is that it lacks any real tone control, so using the tube screamer sounded muddy with humbuckers. I then decided to test it out on big Bertha and while she is 20+ year old modeling technology the screaming pumpkin did pretty well. Using the good old Marshall models and giving them just enough gain to sound good the screaming pumpkin pushed them even further, even at the lowered drive setting on the pedal.

DIY ABY

Back in 2011 I came across a Johnson J3 footswitch at a local Goodwill for $2. Since I don't own the amps or systems this footswitch works with I originally wanted to repurpose it into an A/B/Y pedal. My problem centered around the fact that the J3 has three switches, and while you could use three for an A/B/Y pedal, two will suffice. The switches that come stock inside the footswitch are momentary so that meant I had to order some 3PDT switches. After fewer switches than I had ordered arrived I decided to only use two. Once everything was said and done I stood back and looked at the project and realized just how horrible it all looked with a gaping hole in the center and packed it away in a box to be forgotten.

Now the year is 2020 and things have moved on quite a bit. Other than wiring the project was done, but I just simply can not get over that hole in the center. Yeah, I hate it too, believe me. I had high hopes for this one, but it's that damn hole in the center. Sure I could plug it up, but I just don't think it would ever look right. So what am I suppose to do now? Well I've already made an A/B pedal. It's not the A/B/Y I wanted, but it's something I built myself, it's functional and it will get me close enough to where I wanted to be, all in an extremely small form factor. Not only did I scrap the original project, this article right here has been in draft form for over three years. Don't believe me? Take a look.

And that's just the last modified date,
not when I originally started.

As I've stated in a previous post I decided 2020 was going to be the year I built my own guitar pedals, long before the world came to a stop all at once. I had ordered an exceedingly cheap 1590a style enclosure that was too small to house the fuzz pedal I originally planned to put in there. After some fiddling I decided to turn it into an A/B pedal. One DPDT footswitch, three jacks and a little wiring and this thing came together rather quickly. Although I'm not exactly happy that one of the outputs comes out the top, it's somehow far more pleasing to me than having an A/B/Y pedal with a hole in the center.


I guess since this post was originally about the A/B/Y pedal I may as well finish up by showing some of the progress photos before I decided to toss it in a box and forget it. Someday I might come up with an idea of what to do with it. Maybe an A/B/Y with a boost or volume control to fill up that center slot.. Hmmmm. Now that I mention it..

My Failed Attempt At "Operation: Yngwie on a Budget"

Since the age of 15 I've been a fan of Yngwie Malmsteen, and as soon as I found out about the Yngwie signature Stratocaster I wanted one. Hell, as soon as I saw the DOD YJM 308 on Zzounds for $25 (some 13 years ago) I bought one and only recently started using it with my Kalamazoo Model 1. Being the cheap bastard I am I could never justify the price for the signature strat though, so I decided to attempt the next best thing. In 2009 I decided to start Operation: Yngwie on a Budget, which meant I would buy an inexpensive Stratocaster style guitar and fix it up as closely to Yngwie's signature Fender as I possibly could.

I knew I wanted quality wood and a close match in color, so that meant nearly every Squier on the market at that time was out of the question. Internet research lead me to RondoMusic.com where I found the SX SST57, an alder bodied guitar that was available in what the site listed as a vintage white. Reviews for this guitar seemed extremely favorable and for $100 I almost couldn't turn it down. On the site, the contrast between the white pickguard (triple ply too!) and the so called vintage white was exactly what I was looking for. It looked as close to Yngwie's buttercream as you could possibly get. What arrived was a dented, slightly piss yellow mixed with pure white colored strat with a neck more orange than an Oompa Loompa's dick.


After sitting down with it for a while I didn't really hate the guitar, but there were quite a few problems with it that needed addressed before this guitar would become anything near what I envisioned. However, the more I played it the more I liked it and the more frustrated I became due to the color being completely wrong. The idea of having to repaint it, swap out the neck and replacing all the electronics actually turned me off to the point I used that to rationalize leaving it the way it was. I had grown to love this guitar for what it was, as it was. It's not a top notch Stratocaster by any means but I've since played both Squier and MIM Fender strats that didn't feel as good as the SST57.

Ten years have passed and I recently acquired a Squier neck with the CBS headstock, which I felt would breathe new life into the YJM on a Budget. Sadly, a huge gap in the neck pocket is just too big for me to use anything other than the original neck. That has officially sealed the fate of this guitar. Instead of using this as my YJM clone I'll just be upgrading parts and trying to make this thing a good, cheap strat clone. Sometimes, when the light hits it just right, the paint does seem to be more yellow than it was all those years ago but still not enough to change my mind. I did swap out the bridge for an official Fender PW-29 but the zinc block made the guitar sound way too thin compared to the smaller steel block it originally had. There is also a noticeable gap between the Fender trem and the body, which the original one covered. I like the look of the official trem, but not the tone of the zinc block or the huge gap it won't hide.

Squier neck on SX body.
That gap is far too big to make it work 

For now Operation Yngwie on a Budget has been put on hold. I've thought about finding a candy apple red strat body to pair with the Squier neck, as well as using the PW-29 tremolo, to make a clone of the lesser desired CAR Yngwie Signature model. With some DiMarzio HS3s and the right electronics I think it would make a suitable clone for myself. I may even dabble in scalloping the Squier neck, but all those are just plans right now as I focus more on dialing in the SST57 to be a good stratocaster clone.

Project: Outlet Wii - The Final Peice

It's been over 2 years since I've last stepped foot in the outlet store, although I haven't completely stopped going to thrift stores. Sporadically I've been to Goodwill sales days as well as going to a local Salvation Army store, yet I've never been able to find the final piece to finish off Project Outlet Wii. I found everything, short of a replacement controller, through the outlet store, flea markets or other thrift adventures, yet for some reason I could never, and have never found a Wii sensor bar that wasn't already part of an overpriced bundle.

Up to this point I've been using a wireless Big Buck Hunter Pro bar that is essentially the exact same thing, albeit ugly and eats batteries like a glutton. This meant I would turn the thing on just enough to navigate the menus or get a game started, then I would turn it off and hope that I didn't use up the brand new batteries I just put in the thing, not 10 seconds ago. I do have a few games that require a constant presence of a Wii sensor bar, which I don't play all that often anyway, otherwise causing the game's controls to be horrible or non-responsive at all. I needed to find myself a Wii sensor bar, or did I?

Being the crafty fucker that I am, I decided that I would just compromise and use what I already had, but modify it to work with the Wii's USB ports. It's a super simple little project. All you need is a Big Buck Hunter Pro sensor bar, or analog, which I found at the outlet store years ago, I also often find them hidden among the toys at local Goodwill stores, and a cheap USB cable, which I procured from Goodwill for 50 cents.

While the Big Buck bar only requires 4.5 volts, USB will provide 5, and to be honest I'm not completely sure whether this will shorten the life of the sensor bar or not, but the fact is I'm sick of changing out batteries constantly and I don't often play games that require the bar on the whole time, so I see this as being a necessary evil. Either way I feel this project is worth the attempt as it only cost me about $1.

I simply isolated the 5v source and the ground wire and soldered them to the proper terminals in the battery slot. Then I made a knot in the USB cable and cut a notch in the battery door of the Big Buck bar and voila! Now I have a USB powered sensor bar for about $1. If this thing burns out or dies, I can most likely salvage the USB cable and just find a replacement bar at Goodwill for $1-2 and just do it all over again. Hopefully with the infrequency with which I use the sensor bar I won't need to, but it was well worth a try because now I don't have to worry about batteries anymore!

Outlet Wii Update! Doors have arrived!

All my life I've lacked patience, I haven't a single solitary drop within any fiber of my being. So after a tense 5 days, which honestly is less than I expected, the OEM Nintendo Wii doors that I ordered have arrived! With a knock on my door, the box slid into my hands and away I went to document the arrival!

Pretty much the only thing in the box were these nifty Nintendo bags (which I'm keeping!), holding the doors and the packing slip. I carefully opened the box and bags so I didn't destroy them. Once all was opened I packed the bags back into the packing slip and put them back in the box. OCD anyone?
And so we see that the poor beat up Nintendo Wii that I salvaged from the Goodwill outlet store bins is now almost whole again! The face is still a bit loose, but it stays in place and I never have reason to grab it by the face, so I won't worry about that. All I need now is an official controller and IR bar and everything will be perfect!
