FAMILY="SANSSERIF">I'm tentatively working on a fretless 2-string drone bass
guitar (not a synth... but i might add a lowpass filter whose cutoff is
controlled by a ribbon controller under the fretboard). I'm planning on
not using a standard pickup but instead on using the strings as pickup with a
strong magnet (from a car speaker) beneath them. I do not know, however,
whether the signal attained this way will be strong enough without using a
magnet so strong that the strings tend to stop vibrating rather quickly
(undesirable, as I intend this for drone use). I'm thinking that I'll
put an opamp IC right before the output (ratshack seems to have some for
relatively cheap, if i recall correctly). I've not used many ICs before,
though, so can anyone recommend one for this use and explain where to connect
which pins (okay, my rather incredible newbiness shows itself...) Am I
correct in assuming that I need basically just the + and - connections from
the string and the + and - connections from the powersource (in this case
batteries)? Or are there many other connections to make (possibly a
ground... any others?)<BR><BR>Also, does this make any sense? Will the
output voltage just be too low for suitable audio use? Or will I not
need an opamp anyway?<BR><BR>Thanks in advance</FONT>
