STAGE HOG

 The Stage Hog is a pedal-sized tube amplifier designed for guitar players. The Stage Hog is a 1-watt all-tube guitar amplifier that doubles as a distortion pedal and a low-wattage practice/studio amplifier. When used as a practice amp, the "speaker out" jack can be plugged into any type of guitar cabinet. When used as a distortion pedal, the "line out" jack can be plugged into any guitar amp input.

· all-tube preamp

· all-tube power amp

· buffered output

· Power Scale™ master volume (London Power wattage control)

· high-voltage power supply, so tubes are run in their “sweet range”

· custom made-in-Canada transformers

· 120/240vac mains operation

· remote switching pedal allows Stage Hog to be placed on the pedal board or in the backline with the guitar amplifier.

Tube amp controls:

• Power Scale™ is the propriety technology of London Power and is used under license agreement. PS is a wattage control master volume that allows for varying amounts of power tube coloration (compression and saturation). Lower settings are darker and more distorted, while higher settings are cleaner and brighter.

• Gain control adjusts preamp level

• Tone control adjusts preamp tone

• Voice switch toggles between a "fuller, mellower, less gain tone" to a "tighter, brighter, and gainier tone".

• Mid switch boosts midrange. It is a 3-position type that works as follows: down = mid-boost always off; middle = mid-boost always on; up = mid-boost active only when Lead feature (footswitch) is engaged

• Bright switch boosts treble and acts like a gain switch when Gain control is dialled back.

• Line Out Controls:

• Rhythm Level sets the line-level output going to the monitor amp (high-volume amp); this control is used to match the bypassed signal to the "on" signal when the Stage Hog is being used as a distortion pedal.

• Rhythm Tone controls the tone when the rhythm channel is selected.

• Lead Level sets the line-level output going to the monitor amp, normally adjusted a little hotter than the rhythm level, for a solo boost.

• - Lead Tone controls the tone when the lead channel is selected.

• The Line controls have no effect on the sound when the Stage Hog is being used as an amplifier driving a speaker cabinet. 

• Footswitch:
• The Stage Hog's footswitch provides 3 sounds. 1. Both switches Off (LEDs OFF) = Bypass 2. 1st switch ON (red LED lit) = Rhythm 3. 2nd switch ON (yellow LED lit) = Lead
   
• Back:
• Back view with tube cage removed
• - GND switch is used to eliminate ground hums

• Tubes: 
• The Stage Hog uses two-dual triode tubes: one 12AX7 type and one 12DW7 type. The 12AX7 is the tube on the left-hand side; this is the pre-amp. The 12DW7 tube is the one on the right; this is the power-amp. Since the amp only has two tubes, changing either one has a major influence on the tone.

• The Stage Hog is supplied with current-production tubes. Of course, it doesn't hurt to experiment with different makes and brands, so here are some possible tube choices that can be used in the Stage Hog:
• In the 12AX7 location:

• ECC832 (JJ version of 12DW7)
• 12AU7 cleaner tones
• 7025 US military part #
• 5751 moderate gain (crunch)
• 12AY7 moderate gain with nice clarity

• In the 12DW7 location:
• ECC832 (JJ version of 12DW7)
• 12AU7 less gain and cleaner tones
• 7247 US military part #
•  Tube choices for cleaner tones:
• Running a 12AU7 in the 12DW7 location will provide less gain from the amplifier’s output section
• Running lower-gain tubes such as the 5751 and 12AY7 in the 12AX7 location will provide less gain from the amplifier’s preamp

• 12AU7s in both Stage Hog tube locations for the cleanest possible tones.
