| The Quattro begins with Carl Martin's award
winning Compressor/Limiter circuit with single controls for compression
and level. The Two-Channel Overdrive has switches for on-off, and
for selecting between the crunch and high-gain stages, and controls for
tone and level. In classic fashion, the Tremolo has a speed and a
depth control. Finally, the vintage style Echo has controls for level,
tone, repeat and tap-tempo, as well as an on-off switch. No hard
to read screens, no menus to scroll through, just set-up and play.
There is no simpler multi-effect on the market! There is also an
effects loop built in between the overdrive and tremolo effects for that
special drive or fuzz pedal that is part of your sound.
You also get that famous Carl Martin build quality,
ultra quiet switching, a high quality on-board regulated +/-12V power supply
which allows us to use the finest components allowing the greatest amount
of headroom, and low output impedance which leaves your amp sounding exactly
like your amp.
Compressor: Compression is a very good effect for overall
use, it smoothes out your uneven dynamics, increases sub tones which otherwise
would stay too weak in the overall sound. It also gives more depth, body
and sustain for a fuller sound. This is great for especially solos.
Just set the level knob to match the desired solo level. For more compression
turn the compress knob clockwise, and adjust your level to match the bypass
level.
Overdrives: Drive 1 is the crunch channel, Drive 2 the high
gain channel. To enter drive 1, press the drive switch and set the
level to match the bypass level. The tone knob works like a high
cut filter. Set the knob at full clockwise for high crisp tone or for warmer
and rounder tone, turn the tone knob counter clockwise. To enter drive
2 leave the drive switch on and press the select switch. The level and
tone knobs are the same on both channels.
Tremolo: The tremolo effect is a very useful vintage effect
found on many old tube amp's. The tremolo goes from light and easy
to a mind-blowing chopping effect. The knob works clockwise for more
effect and depth.
Echo: The echo effect is designed to emulate the old vintage
tape echo units, with all that they had in low-fidelity noise and distortion.
It has extremely musical and warm echo, so don't expect any clean sterile
digital delay here. To enter the echo mode press the echo switch and set
the echo level on the echo knob. Turn clock wise for more effect.
Turn the repeat knob clock wise for more repeats. The tone knob works
like a filter with clear crisp echo's in the full clock wise position and
warmer vintage style echo when turned counter clockwise. The echo time
is set on the tempo tap switch and it goes up to 1000 milliseconds.
Please note that once disconnected from power, the echo time will revert
to the shortest time.
Loop: The loop is a serial loop placed between the overdrives
and tremolo, so it's possible to add another of your favorite distortion
boxes with the compressor and overdrive in front of it, and the tremolo
and echo after it. It is also the right place to put in another modulation
effect like a chorus, flanger or phaser. The loop has low impedance
out and high impedance return.
The Quattro is not true bypass, however, the high quality
output buffer circuitry ensures noise free operation with long cabling
from unit to amplifier, even on large stages. |
