Manual
For those of you from Canada, or who know anything about Canada outside
of beavers, and maple syrup…. the capitol of the country is called Ottawa,
and is full of politicians who do nothing but wah-wah-wah all day long (see
where we are going with this?) It’s difficult to say whether there is another
connection between this pedal and the Canadian capitol, but we have redesigned the Optical Envelope Filter, and have given it a new, tongue-in-cheek
name…. The Carl Martin Ottawa!
The Carl Martin Ottawa is an envelope filter that mimics the sound of your
wah pedal without you having to step on a wah pedal and adjust those
frequencies manually. Really a great pedal for solo-ing and for rhythm work,
whether you are into ‘those’ psychedelic 60’s, or the disco era of the later
70’s, or any other music that requires this unique sound. There are 3
presets which are High, Band and Low Pass filters, adjustments for bandwidth and attack as well as level and tone. Let’s look at these controls….
ATTACK
TONE
The Attack knob adjusts the sensitivity of the Ottawa to your
style of playing. As the effect is touch sensitive you will find
that the Ottawa will respond to your attack on the strings….
from a softer darker wah when you play softly to a more
dynamic and dramatic wah (with a higher pitch) when you
become more aggressive. The Attack knob allows you to
adjust how sensitive the effect will be for your personal style of
playing. The control goes from no effect at counter clockwise to
full sensitivity at full clockwise settings.
The Tone knob on the Ottawa, is a high cut filter. With the knob
set at full clockwise, you enjoy the full bandwidth of frequencies, so as you turn the knob counterclockwise, you start to
filter out the high frequencies. On this effect, the Tone control
works interactively with the Attack control, so as you adjust the
Attack, you may find that you have to ‘tweak’ the Tone control
to achieve your optimum tone.
LEVEL
The Level knob adjusts the overall level of the Ottawa.
By adjusting this knob you can match or exceed the bypass
signal

The Q knob adjusts the bandwidth for the Ottawa. At full
counter clockwise you have a
very wide bandwidth which provides you with a soft, round and
warm wah effect. At full clockwise, the opposite is true….the
bandwidth is very narrow and provides you with a sharp,
ear-ripping effect. The setting of the Q knob is very interactive
with both the Attack and Tone knobs, and you may find that
you have to adjust the Level as well, depending on your other
settings.
The Select switch offers three different presets….HP (high
Pass), BP (Band Pass) and LP (Low Pass). These presets give
you everything from the deepest growling 60’s wah effect to
the sharpest 70’s disco sounds…and everything in between.
With the Low Pass setting, the Ottawa is also suitable to be
used with bass guitar.
