Manual
With classic guitar tone disappearing down the road of digital modeling amps and effects, Carl Martin is proud to
introduce the Quattro….four of the most popular Carl Martin effects in one package.
The Quattro begins with Carl Martin's award winning Compressor/Limiter circuit with single controls for compres
-
sion 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 Vintage Chorus 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 chorus 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.
Carl Martin, maximizing transparency, flexibility, simplicity and quality in one package…The Quattro.
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 chan-
nels.

Vintage Chorus: The Vintage Chorus is a very useful effect to
make your tone fat round and singing, an effect very often used
in loads of hit songs from the early 7o´s and up. The Speed knob
set the speed of the modulation, from slow swirl to fast Leslie
like tones. the Depth knob determines the amount of effect wish.
