U U F F E E S S FRONT PANEL: First familiarize yourself with the layout of the Front Panel. Next, remove the footswitch from the transport pouch located inside the cabinet ( combo ) and connect it to the proper jack. RECT-O-VERB Series 2 amplifi ers use a DIN jack located on the underside of the chassis’s outer edge. Labeling which reads FOOTSWITCH SOCKET BELOW should help you locate the jack. SOLO 50 HEAD Series 2 amplifi ers have their DIN Jack located on the Rear Panel proper. (See illustra

CHANNEL / MODE SELECT: Each channel of your amplifi er contains different modes of operation that may be selected depending on your application. In this way you may decide to use the channels for their most obvious sounds or with the fl ick of a switch - invert the channels for the opposite sound style. The voicing of the modes is accomplished by rerouting and reconfi guring the circuit in both pre-amp and power sections of the amplifi er. Here are the choices; HEAD VERSION CLEAN CHANNEL 1 CLEAN

CHANNEL / MODE SELECT: (Continued) MODERN: Aggressive. This is the word that best describes the menacing power of the RECT RECT RECT-OS -OS -OS’ ’ ’ most most rebellious rebellious of of all all modes modes.. 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 MODER

CONTROLS: (Continued) 2.) GAIN - In conjunction with the Tone Controls - Basically, a simple rule applies...as the Gain is increased the Tone control string has less and less effect on the signal until at 5:00 the signal is so saturated that you are getting mostly Gain and very little Tone. Again, this is the reason we suggest using the GAIN Control in its middle region. Here the Tone control string is very active and provides maximum shaping power - allowing you to dial virtually any soun

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 gain gain control control control capab capable le of of taking taking both both CLEAN CLEAN and and PUSHED modes to extremes. Experiment with this cranked region in conjunction with conservative settings of the other tone controls to balance both sound

CONTROLS: (Continued) MASTER: This control is the master feed from the end of the pre-amp to the driver stage and the Effects Loop. As you can see each Channel is fi tted with its own MASTER Control, enabling the two channels relative volumes to be matched regardless of their extremely different sound styles and gain signatures. The MASTER Control makes possible a wide range of sounds through its ability to use very low Gain sounds at high volumes and conversely, high Gain sounds at low

CONTROLS: (Continued) SOLO: This control can only be activated if the correct Footswitch is connected to the Footswitch DIN jack. SOLO is an additional fi nal output level control wired in parallel with the OUTPUT Control. It is capable of a setting above that of the OUTPUT Control and can not be set below. The amount of apparent boost also depends on that of the OUTPUT Control - in that if the amplifi er is at either the extreme low or extreme high levels of the OUTPUT, its effectiveness

REAR PANEL: (Continued) BIAS SELECT: (Continued) chording or soloing, to an all out high gain crunch or lead sound. Players that use mostly these types of sounds may prefer the EL34 clip to the 6L6’s that come standard in the new RECT-O 50 amplifi ers. If you need a variety of sounds and rely on a clean chording sound much of the time, you will likely prefer the stock compliment of 6L6’s that both of these two versions are fi tted with. We feel the 6L6 is a more balanced sounding tube tha
