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-VERBSuse a DIN jack located on the rear of the chassis directly behind the label FOOTSWITCH. SOLO 50 HEADS use a 1/4 jack on the right side of the Front Panel. If the footswitch is not available, you may select the two channels via the manual Channel Select toggle located on the far left of the Rear Panel.

POWER-UP:

First remove the protective covers from the tubes (plastic webbing) before connecting the A.C. cord to a power receptacle. Connect your favorite guitar to the instrument INPUT jack. Flip the POWER switch to the ON position while leaving the STANDBY switch set to STANDBY.” (It is always a good idea to practice this start up procedure as at least 30 seconds of warm-up time lessens the shock on cold power tubes, thus prolonging their life substantially.) Next, using the example below as a guide, set the controls as illustrated and flip the STANDBY switch to the ON position to listen to the two distinctly different channels using either the footswitch or the Channel Select toggle switch as mentioned in the paragraph above.

Before discussing each control, let’s audition a couple of possible ways the two channels might be configured for footswitchable sounds. The first example leans towards a more traditional format with a clean rhythm dialed up on the top RHYTHM ( Green ) channel and a moderate gain, vintage style solo sound dialed up on the bottom LEAD ( Red ) channel.

This second example leans in a more aggressive direction with the top channel switched to PUSHED for a crunchy high gain rhythm sound and the bottom channel switched to MODERN for a blistering lead voice.

NOTE: CAUTION - REDUCE THE OUTPUT LEVEL CONTROL BEFORE PLAYING THESE SOUNDS AS THE ADDED GAIN INCREASES VOLUME LEVELS.

Now that you’ve heard the SINGLE RECT-O 50’S two channels, let’s move on to understanding the controls and their interactive roles in achieving the sounds that you want to hear.
