| Passivly you can't boost only cut. It could be done but in all
probablilty you want a boost (I'm guessing) and it may even load
down the pickup outputs giving you less volume, treble and mid.
They come with a passive treble control....and it's mostly useless
(IMO)

Re: Varitone
The Varitone circuit did indeed use RC (maybe RLC) circuitry to
provide passive tone variations. I have such a circuit on my B.C.
Rich and it works, but without the built-in preamp (volume only,
no active tone) it would be useless as half of the settings give
*extreme* gain loss due to cutting out so much signal. It does
however give a bunch of realy great tones, including some incredibly
nasal ones (more useful for guitar I would think than my bass!!).
Now that active tone setups are widely available the varitone is
kind of obsolete. Rich no longer uses it as far as I know; they
started with them back around 1975 when stuff like EMG or Bartolini
pickup/preamp setups were still a gleam in their designer's eyes.

| 832.3 | So I got a little problem | WAV12::POWELLD | | Fri Sep 09 1988 17:56 | 12 |
| Ok, so there doesn't appear to be a way to add reliable passive tone circuits.
So here's my problem.
I put Seymour Duncan Hot Stacks in my strat and wired them up to switch
between single coil and humbucking mode. In single coil mode they sounded
fine (ie, bright), but in humbucking mode they lost a lot of the high end and
sounded muddy. Now I've wired them back to a standard 5 position selector
with humbucking mode and still seem to lose a lot of highs. I need to regain
the high end somehow. Any ideas?

| Semour Duncan hot stacks sound muddy? They must have changed since
I bought mine, in the humbucking mode they are quite bright, probably
not as bright as they would be run single coil but I never had the
slightest trouble getting an authentic single coil sound out of
them. Perhaps you have your amp's tone controls set a bit on the
muddy side to compensate for the 'single coil' mode...

| I found the problem. I use a master tone for all three pickups,
and it was bad. Put a new one in, and voila, got my highs.

An addition at a late date:
The Craig Anderton book "Electronic Projects for Musicians" has
a schematic for a passive midrange notching control. It only uses
about four parts and would be easy enough for anybody who knows
which end of a soldering iron to hold to build.

| 832.7 | I'll drop it here.... | SMURF::BENNETT | Be Bay Be | Wed Aug 01 1990 15:08 | 33 |
| I put a Fender TBX tone control in my guitar the other night.
This is a control which gives the normal tone varaiation from
1 - 5.5. At 5.5 there's a detent and from there up there's an
incredible amount of `presence' - setting it at 10 yeilds a
stratospheric high end.
I'm curious how it works. Here's the old tone control:
o o o <- 1m/250k ohm pot terminals
| |
| |
.22 cap O \-------- wire to 3-way switch (white)
|
ground
The new one has 2 pots mounted piggy-back with wiring:
(white)--\
|
-NN--o o o bottom pot
/ \
| o o o top pot
| |
| C
| |
ground
NN - resistor
C - .22 cap.
Any takers?
