MODERN:
Aggressive. This is the word that best describes the menacing power of the RECT-OS’ most rebellious of all modes. RECT-OS’ RECT-OS’
A take no prisoners, crushing assault of top end cut and lightning fast response creates a sound of unparalleled aggression that has
set a new standard for hard core sounds. The added tightness of the low end response combined with the radically more present top
end keeps the MODERN mode tracking accurately even at extreme gain settings.
GAIN:
This control adjusts the predominant gain stage in each channels’ circuit with the function and taper being optimized for
each individual channel. Remember that your RECT-O 50 is really two separate multi-mode amplifi ers built onto one chassis, so RECT-O 50 RECT-O 50
though each channel looks identical, the GAIN Control for each channel comes in a different place and adjusts a different point in
that channels circuit.
In most guitar amplifi ers, and especially in all-tube circuits, the GAIN Control is the most powerful
control in the preamp. It shapes the overall style and character of the sound and is responsible for
whether the sound is clean, overdriven or anywhere in between. In your RECT-O 50, the GAIN
Control is even more powerful. It not only determines the amount of drive, but also acts as an integral
part of the tone control string as well.
To simplify the GAIN Controls’ role in shaping the overall tone of the sound we will look at it in two
ways - 1; alone and 2; in conjunction with the tone controls.
1) By itself the GAIN Control has basically three tonal regions -
Low ( 7:00 - 11:00 ) provides the cleanest, least saturated sounds and in this region the sound will be brighter and contain more
upper harmonics lending a three dimensional character to the sound.
Middle ( 11:15 - 2:00 ) enhances the saturation and replaces some of the upper harmonics with a richer, warmer quality and a fuller
bottom end response. Not yet fully saturated, this region is the easiest place to get a great sound in all three channels. This region
contains many of the RECT-OS’ best sounds...especially for soloing due to the crucial blend of an expressive attack combined with
RECT-OS’ RECT-OS’
ample sustain.
High ( 2:15 - 5:00 ) saturates the signal and enhances low and low mid frequencies. While this region provides the maximum satu-
ration and therefor sustain, it also compresses and softens the attack characteristics. For this reason we suggest using this higher
region of the
GAIN Control sparingly and only when maximum sustain is needed.
NOTE: NOTE: NOTE: Due to the RECT-OS’ extreme gain potential, the highest regions of the RECT-OS’ RECT-OS’ GAIN Control may possibly push the pre-amp
tubes past what they can handle, producing microphonic squealing. While we screen and test the tubes your amplifi er was shipped
with and the tubes in your amp passed our rigourous test, we can’t predict how the tubes will respond over time exposed to extreme
gain settings. Your tubes are warranted for a period of 6 months under normal use, but you can save yourself the present and future
inconvenience of having to deal with annoying microphonic tube problems by simply using
a little common sense...Don’t turn the
Gain all the way up!
If you must for a specifi c part or at very low volumes, back down the TREBLE and PRESENCE Controls. Your RECT-O 50 was
designed to provide amazing gain and tone at less than extreme settings removing the need for you to crank everything all the way
up. If you are not able to achieve the sound you want at sensible settings on any or all of the controls, your problem may lie elsewhere
in the signal chain, i.e. pick-ups, cabinetry, processing etc. Keep in mind you can always call on one of our product specialist Monday
through Thursday and seek some advice should you fi nd yourself struggling to get the sound you want.
