Selmer Buzz-Tone

I have been building Selmer Buzz Tones for a few groupies n fans recently. 

Featuring original, near-impossible to source transistors, 2N2613 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 (otherwise it wont buzz!).

Cheapo build for a friend:

Another build.. featuring the Palenque astronaut..


Expensive nos carbon comp build for a groupie:
They all sound 👍🏿.

Ram’s Head Battersea Power Station Big Muff ₽i

    

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 beautiful, post modern view of the Battersea Power Station from Pimlico.

Gilmour used a rams head Big Muff on Animals.

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! 🐣

Maestro FZ-1a Fuzz Tone

dates about 1966-67

 

maestro+epi casino=garage!

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.

Maestro FZ-1 Fuzz Tone

  
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:


Finding 2N270 transistors to buy was HELL. Impossible, hard to find, someone who sells them. Rca’s here in Europe, NONE. Forget it. Until…

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..

Tonezilla mkii

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…
