On eyelet bakelite board.. Those transistor were just a temporary arrangement and off they went once i scored some RCA 2N2613 and 2N408 (as per original pedal).
Here’s the video of the final build.
The sound of garage rock!
Yesterday i was busy making two Klon Centaur clones.
Months ago i bought the last two Chimaera pcbs from the cat over at Grind Customs Fx.
Very well made boards i must say.
I got me some 50 x D9E germanium diodes, the latest darlings of klon builders the world over and plunged into this build, keeping in mind and on the bom the latest (2014) discoveries by the byoc guys on the silver klon (the golden enclosure came first, the silver came later, improving on tone and volume control).
Elna electros, philips, greenies, etc caps.
Metal and carbon film resistors, 1590BB build #1:
I had to lower the value of a 20k log pot down to 10k for the volume knob using a resistor across pins 1-3.
This was made for my friend Luca.
Next, it’s mine:
Same caps n resistors chan pon here.
This time to make the volume pot a log, i used a 10k lin, a 2k resistor from pin 2 to ground.
Same blue minotaur lsd blotter art employed..
On the first build, the gain pot would run funny: regular until 3/4 its taper, then volume would drop.
Heres what i found out about the klon:
YOU MUST audition/measure LOADS of TL072 to get the right balance of clean/gain/volume in general. I have some Texas Instruments and some ST, all of the TI sounded way too “weak”, alas noise would slip through, not enough power, etc. ST’s are better but still, you have to choose the right ones. I did this by ear.
Good TL072s are the secret to this pedal: i tried a bunch of germanium diodes: lots of the aforementioned russian ones, both matched and unmatched, but also Valvo OA81, OA91, RL32S11, AAY22.. guess what? They didnt impart any specific tonal character to the pedal.
As it is, the Klon is a good, clean, very musical buffer/overdrive.
Without a strung out, breaking amp though, i have my doubts it would save the day.
I prefer the good old dirty Rangemaster to the Klon i suppose.
I just rebuilt a friends tone bender mkii i gave him almost 2 years ago. Realised component values were all over the place, my mistakes, crossing oc81d and oc75 schems it seems.. ah beer days..
Now sober as a court jury, i wrote it all down. I made some sort of magic there, the pedal is one of the most powerful mkii i ever made, most likely due to my errors.
The original had carbon comps/ carbon film resistors and dubilier, philips electros, wima caps. This has wima, roe caps and carbon film/metal film resistors but still sounds amazing.
Since he gigs a lot, i had a mission to build it like the proverbial tank.. and to shuffle the controls a bit: he wanted to have the q3 bias out in lieu of the attack pot, that he uses maxed all the time (it now sits inside as a trimmer).
I messed up the decal a bit, hope he wont mind…
Nos italian caps.
I tried a lot of different trannies combos..
Check the usual Soundcloud stream for the full audio repornage.
2n508 on q1, hfe 153
2n1307 on q2, hfe 83
And.. yesterday i listened for the first time to an Iron Butterfly record..
please if you feel inclined, and can stomach bad guitar playing, check out the trannies shootout at the same Soundcloud stream..
Using 2n2222 transistors..
I must say this sounds great. Responds well to volume adjustments, cleans up to overdrive. Very usable.
If you turn down the fuzz it gets all maestro fz1 engulfed-like in a way..
Very vintage and garagey.
Point to point using tagboardeffects’ layout.. with mid cut/mid boost switchie.
And boxed (looks like the lad out of the Crazy World of Arthur Brown!)
My brother took up playing electric guitar again. He asked me for some boxes..
2n1307 texas instruments fuzz face
Q1 hfe 200
Q2 hfe 198
(leakage, wartsnall measurements)
This Fuzzface sounds GREAT. The best i built so far, possibly. Very subtleties responsive, can be hard, soft, gainy, bluesy. Amazing basses.
The other box is a repeat percussion-using BC547 instead of mpsa18.. very quiet sounding, no ticking.
Very happy about these two.
Golden: fuzzface; toy car green: repeat/percussion.
