Since there were some errors on the schematic, please refer to these values should you need recapping your vintage Ace Tone drum machine:
I have been building Selmer Buzz Tones for a few groupies n fans recently.
Featuring rare 2N2613 transistors on choc brown paxoline board, on eyelets just like the original.
One small mod is the cap tuck away under the board, to give it some juice.
Cheapo build for a friend:
Another build.. featuring the Palenque astronaut..
When i was a Londoner, id often catch the 24 bus on sunday mornings from Hampsted Heath to its final destination, Pimlico. There was a pub there, next to the bus station where we would go have brunch and shoot pool. In the afternoon we would visit the Tate, usually.
And we would enjoy the haunting, post modern view of the abandoned Battersea Power Station from Pimlico.
Gilmour used a rams head Big Muff on Animals apparently.
Built for a friend on a pcb by OP ELECTRONICS, IT. Transistors BC239C from ebay seller, Whazzgroover. Sprague caps, etc
First time i mess with a hot glue gun, and i guess you can tell! 🐣
Syd Barrett’s hairy boost.. VERY WARM AND THICK. Perfect counterpart to Syd’s favourite amp settings, basically treble at 10.
Perfunctory build on eyelet board, with external vero for transistor testing, using 2N2613 as per original.
I also made a quick little excuse for a tune to test it further.. sorry for the hurried and far from great mix:
Well.. At last i can say it: my clone (see back pages/older posts) sounds GREAT. Against this original (2N2614 transistors), with little or no attack pot excursion, aka max it or it wont fuzz, my clone is a pot full of sweet spots. Maxed, it is plain evil. Compressed.
Comparison, original vs my clone:
Still, the original has got so much mojo.. Magic. I will not mod it to bias the transistors better. As the Poets said, THAT’S THE WAY IT’S GOT TO BE.
The first fuzz box.. The Satisfaction horns sound, the star of so many fuzztonic records. I had to make myself the perfect clone! Yes i built a couple of these before, but i wanted to build it properly.. This is what i came up with:
I did find them! A small stash of them actually! And i didnt have to sell my body to get them. Not RCA’s, but NOS 2N270: leaky, gainy, nasty 2N270s!
Next, i set up this testing board with a nice ZIF socket!
First good set-listen:
Q1 hfe 79 lkge 0.12mA
Q2 hfe 168 lkge 0.53 mA
Q3 hfe 131 lkge 0.70 mA
I tried inverting Q3 and Q2 but the distortion was oscillating..
Nos brown Mullard like baguettes ahaha and other stuff i found at my local baker..ahah and three oc84s..
I have been building pedals for little over a year now.. here are some of them:
Vox repeat percussion
The Vox Repeat Percussion is featured in the most unusual spots in 60es music, often used on organ too!
Here is my tagboard build.
I love this effect.
Turns your guitar into a mandolin.
If you dig the first electric prunes lp and early pink floyd, spacemen 3, this is the one and only vibrato for you!
Candysweet carbon comp resistors, philips, tropical fish caps blah blah.
Caution: the musical shredded by this pedal can cause epilepsy. Or tripping on out. Or both for max freakout! Ahahaahaha
The germanium fuzz face is one of the key 60es pedals.
Here are a couple of builds..mojo stuff. Carbon comp resistors, tropical fish, philips, tesla caps, vintage texas instruments transistors (gold plated pins) or good old ac128s or Nkts..whatever sounds great.
That ugly blue n white trimmer there is bound to be replaced with a funky resistor as i am finalising the pedal for my mate Reverendo Mud’s 60es garage band, Seuss.As for any fuzz box i build, i put my ear on it: i like them with lots of attack i like the pick to be leading.. That is more apparent on my Tone Bender mkii builds, though.
LISTEN to this specific one:
A brown paxoline 1st revision build:
Shin-Ei Uni Vibe
Univibes.. i like building them. I have a few done now.. a couple of them can be handy.This circuit is one of those PERFECT circuits: mojo components or crappy ones wont change its soul..this heavily populated board vibes on whatever you put in it.I chose to make one that will LAST so no corners were cut..Cute Sprague electrolytics, tropical fish caps, etc all class A stuff here.
This is a classic vintage univibe build, with the best components of today.
The hard part of this build is the tuning part..that is, setting the character of the pedal..its very soul and sound.Back in the 60es the inventor of the Uni-Vibe Fumio Mieda would do this by ear, box per box, to imitate the sound of a rotating Leslie speaker.
Just like Mieda sensei, I tune each univibe by ear. I have my Leslie speaker here as a template!
Now Mieda san is the CEO of Korg…and the mighty, beloved japanese giant as part of the new craze of re releasing its legendary vintage gear is producing a new run of Univibes…they had to change the name though…cos they sold it to Jimmy Dunlop.No Hendrix scholar can go about without one of these.. forget about massively produced, digital, fake analog vibes.
This will make your head spin.

This 60es univibe clone will take its place in a gigging venician musician’s rig.
Very rough, temporary artwork.. hes rushing to a gig tomorrow so…no time to make it nicer really…but what do we care for..
I also had to build an ac dc power supply outputting 18 volts for this.
Because of the no-mojo components, i must admit its bite is not as apparent and imposing as in my other builds.
Still..it sounds miles and miles better than any of those fake ass Jim Dunlop univibes…ahahaha!!!
PCB by Redhouse (forum vibe pcb, classic build)
Maestro Filter Sample Hold
My Maestro Filter/Sample & Hold build.No artwork as yet…who cares, like.
Pure analog pleasure/madness..up sweep, down sweep, resonance, speed…any control..you name it, theres 5 knobs of it!
This is one of the hardest clones to tackle.
I made two, one for the man and one is currently being debugged to be given as a gift to my gonzo mate Jackit.
Amazing filtering and funky funky s&h…pedals like these are just not made by pedal corporates anymore.
