Now that Christmas is over, I have time to reply.
If you are referring to my Judas Priest pedal above, then it is a 1590X enclosure – 5.72 inch (145mm) x 4.77 inch (121mm) x 2.22 inch (56mm). It was needed so that 6 Marshall type knobs could be arranged across like on an amp face. Plus I needed room for GBOF, Rototone, PlexiPlus and ToneTweq boards along with the obligate 3PDT board on the footswitch.
If you are referring to the NostalgiTone 70’s, then it is a 1590DD according to the Tayda document. Tayda is where I obtain the majority of my enclosures, some pre-drilled and others that I drill myself and their enclosures are well done for the money, although shipping has gone up recently.
Early Judas Priest is definitely a good use for this pedal as your demo shows, Barry. From the Sad Wings days to at least the Hell Bent For Leather era.
It would have been great to meet Glen Tipton and Ken (KK) Downing back in the day and I certainly would have loved that (actually it would be great now). I started listening to Judas Priest back when the Sad Wings album came out during my college days. It is still one of my all time favorite albums and my favorite of Judas Priest. A few years ago I had worked out the entire Dreamer Deceiver song, which is my favorite all time Priest song. I have a lot of the earlier JP stuff on vinyl, although later got digital copies of the same albums. One of my college roommates had Rock-a Rolla, which is a weak album, but JP had no choice in the way the album was mixed or recorded, and their heavy sound was toned down for some reason on that album. I also listened to the early Scorpions (Uli Roth version), AC/DC, UFO, etc. back in my college days, and my roommate and I took a lot of grief from others on my dorm floor, telling us these bands would never make it and nobody listened to this music.
Years ago, the first concert I attended with my new girlfriend at the time (and now my wife of 36 years) was Judas Priest during the Point of Entry tour, also for the large sum of $10. JP and Sabbath were the two main reasons I started my quest for treble boosters in the early 2000’s, since I had found out that was a large component of their sound. I have built seven treble boosters over the years (2 Rangemaster based, 4 Hornby Skewes based and one Naga Viper based). Looking at the NostalgiTone 70’s schematic, I know which one was used along with the British amp “model” circcuit. A bit different than mine, but similar concept.
Judas Priest pedal revisited below.
I loved the Sabbath demo for the Nostalgitone 70’s – great playing Barry! Sounds spot on!
The Judas Priest pedal I built awhile back seams similar to the Nostalgitone 70’s. A Rangemaster into a Plexi Plus with a ToneTweq. I don’t know if the Plexi Plus is the basis for the Marshall-like section of the Nostalgitone, but I wouldn’t be surprised it is.
I notice the matching fingernail polish color. Was that on purpose, LOL?!
Very nice pedal graphics! It makes me want to up my game.
Thanks Wilkie. That’s what I thought. I figured I could jury rig the electrolytic if I had to – I have done it before on other projects. If I ordered the correct part from Mouser, it was only going to have to pay a mere $8 in shipping for a part costing less than a dollar.
I will check the MLCC’s that I have for the value closest to 1uF (least % variation).
Losing things do to a glitch/website error sucks for website owners, especially if they act as their first line IT specialist. Always bad to lose recent data. Maybe backing up the shop portion of the site daily, if possible, might be a good idea. What happened really doesn’t matter to those who read the forum for fun and entertainment. I can always repost my recent builds. But to the site owner with a “store” really hurts and means a lot of work.
This just reminds me to fix problems with the back-up software (auto mode) I have on my own PC.
Ditto what Barry and Cybercrow wrote. I first used a $20 tester off Amazon and got ballpark figures for transistor gains and leakages, but graduated to using a DCA55. I still use the cheapie tester for double checking diode anode/cathode positions as they can be different from one Ge diode to another. I also use it to quick check resistor and capacitor values, but that is pretty much it. For semiconductors, you really need to use a Peak Atlas device.
Thanks a bunch to both Wilkie and Barry for your comments and contributions to this thread. Can’t say when these projects will be done as I have 11 build projects lined up to do right now as well as 5 pedal mods to go back and complete.
Happy Birthday – belated. Have been on the road in northern Minnesota near the Canadian border and without cell or internet service for a couple of days.
Thanks Wilkie. I had also done some reading along this line and some of it was beyond my limited electronics knowledge to completely understand how to figure things out. I just started looking at some of the available schematics for various treble boosters and found that the most common filtering is a series Shottky diode for reverse polarity protection with a 47uf capacitor to ground for noise filtering. So some people have already done the work for me I guess and that’s what I will try, at least at first. Similar to the One Knob Fuzz schematic but with a larger capacitor.
I have never done this mod, but it is included in the “Big Steaming Pile O’ Mods” for fuzz face type circuits. These mods can be found on the http://guitarpedalbuilders.blogspot.com webpage. This is a very easy mod as all one has to do is place a B100K pot between the 9V power supply and the 9V power eyelet on the PCB. If using a BYOC 3PDT board, the mod would appear as in the below drawing. The 100K pot value allows one to take the voltage down to zero if so desired.
Got a few.
First off Judas Priest Drive – GBOF Rangemaster / Tone Tweq / Plexi Plus / 3PDT Board
Llama Drama – Stock Angry Llama / 3PDT Board
Power Driver – Stock Colortone Overdriver / 3PDT Board
Ornery Shrewes Treble Booster – Ge Hornby Skewes Treble Booster built with a GBOF / 3PDT Board / Tone Tweq
Amp Punisher – Si Hornby Skewes Treble Boost with Tone Control built on GBOF / 3PDT Board
Industry Fuzz – Stock Industrial Fuzz / 3PDT Board
Ranger Danger – PURP / Tone Tweq / 3PDT Board
Vox Tonebender (Similar to TB Mk1.5) – PUFF / 3PDT Board
Sam’s Fuzz – Stock Fzzz Bxxx / 3PDT Board
New pictures as previous ones were not the greatest due to the camera I used. Currently working on a GuitarPCB combo build, which should be posted in a few days.
Ask and you shall receive. I will say this fuzz is a bit gnarly, a little bit more rambunctious than a Fuzzrite (e.g. American Fuzz Pro). It is really fun to play with. Gutshot below.
I had a somewhat similar need for my home hobbiest rig. I wanted a speaker cab switcher, but found no PCB project that could accomplish this as the load (speaker impedance) seen by the amp needed to be continuous to protect the amp. I settled on a Radial Cabbone that I got off Reverb used for slightly more than half of what a new one costs. Protecting a $1000 tube amp is worth it.
I actually think I asked about building something similar a few years ago on this forum and got the same advice. Listen to the experts such as Barry on this forum as they provide good advice.
