Rocktron Tsunami Chorus $109.99
Analog circuitry with some extras like Ambience, which puts a small delay between left and right stereo channels.

This chorus stomp box that offers two modes of operation – both chorus and
ambience! Often the choice of professionals, the Tsunami offers the much
construction and unique imaging make it a real Rocktron classic.
The dual switch setup features depth, rate and delay for chorus; while
Rocktron’s exclusive "Ambience" control allows 0ms-30ms of carefully
contoured room delay, which is great for creating a huge stereo spread or
"doubled" sound.

The chorus mode utilizes a modulation circuit to vary the pitch of the delay
signal. The chorus effect is produced by varying the rate at which this pitch
occurs. The delay control adjusts the range in the delay mode where the
modulation will occur. This will also adjust the intensity of the chorus effect.
The ambience mode is a straight delay mode with its own adjustable delay
control. This control has a range from a very short delay (5ms) to a small
slap echo (28ms).

Utilizing both outputs in stereo produces a very wide effect in both modes.
Guitar Shop Magazine said: "A very interesting feature (and one that might be
overlooked if not fully explored) is the unit's output section. It has a single
input and two outputs much the same as most "stereo" chorus units. The
difference here is that one output puts the effect in phase with the dry signal,
while the other gives you the wet and dry signals out of phase. With the dual
outputs, when used in stereo—either through a mixing board or with two
guitar amps—the combination of in- and out-of- phase effects together
provides something very special. Your run-of-the-mill chorus unit's stereo
output will not provide this degree of colorful spatial manipulation. Also, be
sure to try both outputs even when using the box in mono. You can achieve
cool, subtle differences using one output or the other."

The Tsunami's heavy-duty extruded metal chassis is built to take a beating
with counter-sunk controls and sturdy switches. No cheap plastic here! Like
all Rocktron effects, signal integrity is maintained by providing a direct signal
path, with the effect making the Tsunami one of the only chorus pedals that
works well for both clean and super-saturated tones. The finely dampened
chorus will not get "tinny" or "thin", but rather creates a lush new dimension
for your all-important tone.
