DO NOT REMOVE FROM CASE. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. GENERAL DESCRIPTION The Peavey Butcher® has been designed to faithfully reproducethe searing “crunchy” sound sought after by today’s demanding hard-rock guitarists. All controls and functions have been specifically tailored to produce the ultimate in tonality, distortion, and sustain characteristics. The Butcher will deliver 120watts RMS into load impedances of 4, 8or 16ohms, and is capable of driving multiple enclosures for those players wishing to achieve truly overwhelming sound pressure levels. Its construction will allow the Butcher to withstand the rigors of use in a night-after-night touring environment. The cabinet is constructed of %" wood and is covered with the heaviest available 34 oz. Tolex™. Ruggedness is enhanced by huge metal corners and a steel-reinforced carrying handle. Internally, the Butcher features chassis construction of 18 gauge steel, massive steel-mounted transformers, and the finest components available. The all-tube circuit utilizes time-tested European ECC-83/12AX7A preamp tubes and proven premium STR6L6GC output tubes. The Butcher’s straightforward design allows for relative simplicity of operation. However, in order to avoid potentially hazardous or damaging situations, please read this operating guide carefully and completely. Although the Butcher will provide excellent tone when used with any high quality musical instrument enclosure, the Peavey 412M™ and 412MSrM enclosures have been specifically designed to produce the ultimate rock’n’roll sound when used with the Butcher amplifier. If you have not already done so, we urge you to audition your Butcher with one or more of these remarkable enclosures at your nearest Peavey dealer. POWER ON/OFF SWITCH The Power On/Off switch is a simple two-position switch which controls AC power to the amplifier. STANDBY/ON SWITCH The Standby/On switch is a simple two-position switch that allows the amplifier to be placed in the standby or active mode. GROUND LIFT SWITCH This switch is a three-position type with the center (0) position completely removing the internal grounding capacitor from the circuit. This position is recommended for situations where the AC power receptacle is known to have a properly grounded third wire. When only two-wire service is available, a suitable ground lift adaptor should be used. In this situation, the plus (+) and minus (-) switch positions may be used to properly ground the amplifier. One of these two positions will yield the lowest amount of hum or "popping" when the instrument is touched. NOTE: The Ground Lift Switch is not operational on 220 volt and 240 volt export models. BOOSTER OUTPUT The Booster Output jack provides a line-level (IV RMS) signal for purposes of driving additional power amplifiers. Since the Booster Output signal is taken from the output transformer, all amplification processing (including the tube-type power amp) is reflected in this signal. SYSTEM PRESENCE The Butcher incorporates a System Presence control for adjustment of very high frequency signals (5 kHz and above). The System Presence control occurs in the circuit path after the equalization controls; it is, therefore, post-EQ. Since the System Presence control is active, it is capable of boosting high-frequency signals and allows fine tuning of tonality, particularly when the amplifier is operated in a distorted mode. It should be noted that many popular speakers and enclosures are limited in their capability to reproduce certain frequencies. In some systems, the System Presence control may not yield significant changes in tonality. Obviously, boosting a certain frequency range will produce no audible result if the speakers cannot reproduce that particular frequency range. EQUALIZATION The Butcher features three bands of passive equalization (EQ) with controls labelled Low, Mid, and High. These controls are traditional in operation and provide a wide range of tonal output. Again, experimentation with various equalization control settings will determine which combinations yield the best results. Since the Butcher’s equalization is passive, it is recommended that one or more EQ controls be operated above minimum (counterclockwise) settings. When all EQ controls are set at minimum, the equalization stage is, in effect, cutting all frequencies. The audible result of such settings is simply a reduction in overall system volume level. With guitar signals, extreme bass boost does not add significantly to the amplifier's projection capabilities, but it does consume a disproportionate amount of the available power at the expense of the mid and high frequencies. Since mid and high frequency controls are critical to the ultimate tonality of the Butcher, Peavey’s design engineers have chosen to deliberately limit the function of the Low EQ control. GAIN CONTROLS The Butcher features Pre and Post Gain controls whic...
