Hey all;
Still plugging away at getting my pedalboard pop free. I use a transistor to
switch amp functions, as shown below:
+15v
|
control voltage ___ |/
o--------o-|___|- -|
3k |>
|
o
|
|
|
o
GND
(created by AACircuit v1.28.6 beta 04/19/05 www.tech-chat.de)
The 15v is from the amp, and switching it to ground turns the amp function
on or off (e.g. channel switching, volume boost). It switches dead quiet in
one direction, but there is a pop when I switch back. I put the circuit on
the scope, and found that it switches cleanly to ground, but when I switch
back, there is a little spike in the waveform just before the beam goes to a
higher position on the screen. I assume that this is my audible pop.
Any ideas as to why it's there and how to get rid of it?
Thanks
