Title: Cap Decade
Post by: ash on June 25, 2014, 12:27:08 PM

Hi,
great forum you got here...
I am new to circuit bending and have been reading up on stuff..
and thought building a bend box was a good first move..
Any ideas on what size caps i should go for on a selector switch of twelve

i'm not sure that caps are that much use on a bending box.

I've always got by with a resistor box and a couple of meter probes

I was following Reed G's bend box construction and thought it a necessity...
I was wondering how it would be used lol
Which WAS going to be my next question..
Thanks for the reply..  :)

Just found this..
Capacitors, again available in a wide range of values, can be wired between the pairs of points. These may change the tone of the effect produced or pulse the sound in differing ways.

well you can sometimes get pulsing effects, but without any control over any depth or rate. You'd do a lot better to build an LFO of some kind.

I'd say capacitors are probably the least useful common component if you're using random bending techniques. They are a lot more usable once you learn some electronics theory.

Rather than worrying about capacitors holding a charge, as suggesting on that link, i'd be a little more concerned about connecting a cap backwards across a voltage and it blowing up in your face!

i found caps really good in my caiso sk 5 between the bend points on the two main chips.  With out a cap the sound often hangs.
