quite possibly the coolest phaser ever built... some day i will own one of these. I missed a broken one for $100 on ebay a while ago. :(

enyone??? better pic....schem???

Here is FSB-birthday present No. 3, the very sought after:

Hey folks, nappyD here. Does anybody have a schematic, or know how the MicMix Dyna Flanger works? Are there clones out there?
It's the Zappa flanger that renders that format vocal quality when used in conjunction with a great wah pedal.... I can't find anything out in the google universe about it. Please help.

Thanks,

Picked-up another Colorsound recently for the collection, the Overdriver is essentially the Powerboost, the pots on the pcb date to 1979, Macari's apparently started putting the 4th knob on because of volume control requests, I've seen a couple before and theres a few reviews on HC.

I've build the overdriver / powerboost many times but this one sounds f***ing amazing in comparison!

Ever seen one of these rotary speakers (scroll down for Rover) ?:

Nice old pedal, metal can BC109 and a 2n3819 and some bloody massive old caps :D

Lots of board pics for tracing

In all my years of looking at Fuzz Faces, I've never seen one with a mustard cap for the output cap...

This guy has TWO for sale.

He doesnt mention the switch changes, and the wiring looks awfully messy...but here are pictures of BOTH.

Have you guys ever seen mustard caps in FF's ?

Anyone have the schematics for this, I got a (more or less) non-working one cheap. Some of the leads have been pulled loose from the pots, and someone tried to fix, obviously didn't get them all in the right places. But the delay does work just not adjustable.

I think this is pretty rare - the early version with the knobs closer together. Not sure what other differences there may be.

Hello.

I see connection diagrams of HEATHKIT TA -28 well, but there are little the inside images.
It is the image which it found at auction.

It is the layout that it watches a connection diagram from this image, and it thought about.

When there was a mistake, please teach it.
I am sorry in strange English.

I'm building a MK II and MKIII. I got both sets of transistors from Small Bear. The MKII Pro set has 3 transistors, each bag labeled 70, 76, 130. Are these to go in order; Q1, Q2 & Q3?

And for the MKIII the bags read; 70, 91, 114, are those also in order: Q1, Q2, Q3?

Please let me know thanks

Complete with goop....

While reading the excellent book Strange Brew a day by day historical overview of the Mayall/Clapton to Cream etc... era in Britain, I came across a line where Peter Green talks about not liking fuzzes and also another part that discusses how he used a homemade unit he called the Buzzeroo . (page 93 second last paragraph left side of page) which reads, The live instrumental favorite Curly is boosted by Green playing through his homemade fuzz box (nicknamed The Buzzeroo ).
It begs the question;...

Do OC44's rival NKT275's in a fuzz face circuit?

Which you can buy here for $500 look more like a later version in a Cry Baby case. Here are some pics of an earlier Jen Double Sound

Hi,

I'm new to the forum, and come in search of knowledge.
I've built a few fuzz and OD boxes and am sort of familiar with transistor and diode clipping, but I'm about to start building a red llama clone, and looking at the circuit have a few questions..
1: the red llama uses an IC with 6 invertors, but only uses 2 of them. Why? Why not use and ordinary 741 op amp?
2: where's the clipping come from? There's only 1 diode?
3: will a 910K resistor work the same as the 1meg ones in this circuit,...

It is exactly the same as the Locobox Mysto Dysto and basically a Distortion+ followed by a Big-Muff-style tone-control.

It should not be confused with the Electra Distortion schematic floating around (from which a lot of overprized boutique pedals are based on e.g. the Lovepedal COT 50). The Electra Distortion schematic seems to be not from a pedal, instead it seems to have been built in a guitar as can be seen in the advert below.

For anyone that is a fan of the Rat. Here is a webpage I threw together.

Some blurry schematic shots and some decent closeups

Back in 1977 I built a sort-of EH Electric Mistress clone. I tweaked a few things and ran it at 15V (recommended for the SAD1024 instead of 12V. Just one problem; the LFO wouldn't run. Unless I poked it with a scope probe. As I was gigging at the time, I was in a hurry to get it working, I stuck a 6pF capacitor in the appropriate place and voila! I had a triangle wave with a small notch in it.

A couple of months back I decided to sort this notch out so I decided it must be that the flip-flop...
