Introduction
The Cave Vibe is a unique vibe effect. It has been specially adapted to include an internal 18v charge-
pump to provide more headroom to the effect. This charge-pump is made switchable so you can
bring it back to the original if needed. This effect functions best with a 9V wallwart adapter and it is
advised not to use 9V batteries. Once the battery is drained too much, the 18v charge-pump may
function erratically due to the low voltage.
Also note that operating at 18v on the highest intensity and voice settings, you might hear some LFO
ticking. In this case turn down the intensity and/or voice just a little and the ticking will disappear.
Building sequence
Soldering this board can be very complicated for some people since the solder pads are very close
together. Use a magnifying glass to make the job easier. If you want to experiment with other
transistors
, LED and LDR’s
the
n you could socket them instead of soldering them to the board. You’ll
need a 20 SIL sockets. Break off the sockets and solder them to the board.
Start by soldering the resistors. If you want to socket the transistors then solder the sockets now.
Note:
Do not blow on your solder in an attempt to cool it down. That will possibly result in a bad join
that might corrode!
Solder the diodes, the ceramic capacitors and then the IC sockets. Next, solder the SMF and MKT
capacitators. Finish by soldering the transistors and electrolytes.
Now.. what did we forget? Yes.. the LDR’s and LED.
If you do not want to experiment then now is the
time to solder them. I advise to solder the LED first and only then the LDR
’s
. This will enable you to
better position the LDR’s. It is advised to position the LDR’s parallel against the LED:
Place the transistors (if socketed)
and IC’s
and you are almost ready to rock.
Besides the components mentioned in the Bill Of Materials table, you will need:
•
2 input jack sockets
. 2 mono jacks if you are not going to use a battery but only the 9V
adapter. 1 mono (for output) and 1 stereo jack (for input) if you will be using both a 9V
battery and the 9V adapter.
•
1 x 3PDT footswitch
(9 pins)
•
2,1mm DC jack
socket
(isolated).
•
9v battery clip
(optional).
•
22 gage stranded hook-up wire.
•
A LED holder.
This enables you to mount the LED in the enclosure.
•
Hammond 1590BB
case (or similar) in your favorite color.
