HEAD VERSION

REVERB: RECT-O-VERB / COMBO & HEAD These self explanatory controls deliver the rich natural reverb sound. Although the circuit is the same for both Channel 1 & Channel 2, the amount of REVERB available is not. In Channel 2 there is slightly less REVERB available overall because of this channels’ very nature.

The reason behind this is two fold: 1.) that it is easier to prevent the massive amount of Gain and signal strength present in either of Channel 2’s high gain modes from causing unwanted REVERB oscillations.

CONTROLS: (Continued)

As Channel 1’s MIDDLE Control is swept past 1:00, it quickly starts to add gain in these midrange frequencies adding cut and punch. As the top end of the control is reached, ( 3:00 - 5:00 ) it becomes an additional gain control capable of taking both CLEAN and PUSHED modes to extremes. Experiment with this cranked region in conjunction with conservative settings of the other tone controls to balance both sound and feel. While this added fl exibility may make Channel 1’s MIDDLE Control a little more tricky to learn at fi rst, it will become quite valuable as you start to realize the power of this super versatile channel.

BASS: Last, but not least in the string of tone controls we come to the BASS .This control works similarly in both channels in that it determines the amount of low frequencies present in a sound. However, the actual frequencies and style of lows it mixes in changes from channel to channel. Like the MIDDLE Control, it falls in line signal-wise after the TREBLE Control and the same scheme applies.

When the TREBLE Control is set high, the effectiveness of the BASS and MIDDLE Controls is reduced. If the TREBLE Control is set low these two controls become dominant.

BASS MID

For the most balanced sound and a balance of power between the three rotary tone controls, try to use the

TREBLE Control in its middle ranges.This scenario produces nearly equal representation of all the frequen- cies on the tone controls and provides a great neutral starting point for further tweaking.

HEAD VERSION

PRESENCE: The PRESENCE Control is a high frequency attentuator that is placed at the end of each channels pre-amp stage and affects frequencies higher than those of the TREBLE Control. It acts independently of the other rotary tone controls and is crucial in voicing the Channel. It is a powerful global tone control. Lower PRESENCE Control settings darken and, in fact compress the signal which works well to fatten single note solo sounds, giving them girth and focus. Some of the best lead sounds in your RECT-Owill

fi nd the PRESENCE Control in its lower regions, where a balanced, vocal response is achieved.

PRESENCE BASS

Higher settings unleash the mighty roar of your RECT-Oand this can be great for sparkling clean sounds in Channel 1 and more aggressive crunch rhythm sounds in the high gain modes. Be sure to taunt the beast that lurks in Channel 2 MODERN as the PRESENCE is truly amazing in this most agro mode.

			2.) This channels aggressive nature lends itself more to musical styles where high settings of
			REVERB are simply not traditional. Don’t worry...there is still plenty of REVERB for drenched solo
ENCE	REVERB	MAST	work in both the RAW & MODERN Mode in Channel 2. Simply run the REVERB Control a little
			higher than that of Channel 1.
