Overview:
Congratulations on your choice of the SINGLE RECTIFIER 50. You have purchased a handbuilt instrument of the finest quality
and craftsmanship. A unique blend of yesteryears’ black magic power section design combined with our race-shop approach to finely
tuned, high gain pre-amp circuitry leaves the RECT-O 50 standing alone...instantly a classic destined for vintage status. With two
channels housing four definitive and distinctly different Modes, a complete array of amazing guitar sounds can be obtained quickly
and easily.
Looking to the Rear Panel assures that all your interfacing needs are covered. A Parallel Effects Loop with a MIX control provides tone
insurance for even those questionable effects. To use the SINGLE RECTIFIER 50 in larger rack systems, or to interface to other
power sections, the SLAVE jack and is a welcome feature. Two speaker jack combinations have been provided - two 4 Ohm and one
8 Ohm - to ensure the proper impedance match to many types of speaker enclosures. The other features will prove to be quite
valuable to you and further along in this manual they are covered extensively.
