INTRODUCTION TO THE RAMSEY RV1 REVERB EFFECTS:
We're sure at one time or another you wished that your TV had surround
sound during your favorite action move or game, or that you had some reverb
effect on your ham radio or CB, or even that your voice had more depth and
reality. These are not the only effects you can do with this kit, there are many
more. We leave more ideas up to your imagination, as it is rewarding to come
up with your own uses for a neat kit like this.
This kit is designed around an IC that uses a set of switched capacitors
called a bucket brigade device. The IC works just like it sounds, with
successive capacitors ("bucket holders") passing their charges from one to
the next on every clock cycle. When the device is running, it causes a time
delay from input to output determined by the clock rate, and the number of
"bucket holders" that the device has inside. When this delayed sound is fed
back into the input, with some decrease in level, it has a reverb effect such
as echoing in a room. This has the same effect as the old reverb spring units
that were inside of electric guitar amps and other equipment, but is immune
to mechanical shock unlike the spring units.
Not only will you find this kit very useful, you'll also find it enjoyable to build,
whether you are a beginner or an experienced kit builder.
NOTE TO NEWCOMERS: If you are a first time kit builder you may find this
manual easier to understand than you may have expected. Each part in the
kit is checked off as you go, while a detailed description of each part is given.
If you follow each step in the manual in order, and practice good soldering
and kit building skills, the kit is next to fail-safe. If a problem does occur, the
manual will lead you step by step through the troubleshooting guide until you
