BOSS OD-1
This is a BOSS OD-1 DIY project, from a beginner to
a beginner. I wanted
something more complicated than a Fuzz Face, but still
easy and 'modable'.
Also I tried to do something that cannot be found on
each DIY site. I had
an OD-1 service manual collecting dust around, and that's
how it started.
First and foremost - BE CAREFUL. This project involves
etching a PCB with a
very strong and dangerous acid [read about it here],
cutting the PC board
which can also be potentially dangerous, drilling holes
in the PCB as well as
using a soldering iron. This project is a hobby project,
it is NOT intended
to be used comercially.
I WILL TAKE ABSOLUTELY NO RESPONSABILITY
FOR ANY KIND OF
DAMAGE YOU DO TO YOURSELF, OTHER PERSONS OR EQUIPMENT
AS A RESULT OF FOLLOWING THE INSTRUCTIONS ON THIS WEBSITE!
This project is still in a test phase ( Nov. 2002 ), and functionallity
is NOT guaranteed.
Use it at your own risk.
Now, after this introduction, if you're still with me,
let's begin with the project:
You will first need the [schematic]. Print it out.
Study it a bit, if you know how to read
schemes. If you don't know what all those components
are, go [here].
You will, of course, need some tools to finish the job:
|| 15W - 30W [soldering iron]
|| some [solder]
|| [tip cleaner]
|| [saw] to cut the board
|| [file] to
smooth the edges of the PCB after cutting
|| [pliers]
to cut and bend component leads etc.
|| some [etchant]
|| [plastic box] for [etching process]
- PLASTIC, NOT METAL!
|| mini [drill]
to make holes in the PCB - 0.8mm-1.0mm
|| DMM - a cheap one will do
|| [circuit components], according to the
schematic
It is generally a good idea to have all the tools and
circuit components ready before
going on with the construction. But, hey, it's no must...
You've studied the schematic a bit, right? You've noticed
then that it consists of two
transistors and a dual-opamp. I had no transistor or
opamp designation on my
schematic, and assume that these are 'generic' low noise
type i.e. use whatever you will.
Mine was tested with 2SC2362 and 2SC1571 transistors
and TL072 and JRC4558
opamps with nice results. I could almost bet that 2SC1815
or BC547/BC548 would
work. The pinout for the BC547/8 differs from the rest
tho'. As for the opamp - try any
that you would try in the TS.
Let's go now to the [next page]
