  • Page 5 Randall Smith and MESA Engineering®. The Limited Edition KING SNAKE™ you have chosen is legendary in both sound and story because it is the direct descendant of the original Boogie that stood alone at that intersection so long ago. That amp was the transitional link between the low gain single channel amps of yesteryear and today’s high gain, multi-channel footswitching amplifiers.
  • Page 6: Overview

    On the KING SNAKE, the three-position Multi-Watt switch offers a choice of the full 100 watts of Class A/B power produced by all four 6L6s, 60 watts of Class A/B power that runs the inner two 6L6s and 10 watts of Class A Single-Ended power running the two left-most 6L6s for the ultimate in sweet, clip-able power.
  • Page 7 Of course, what would a re-creation of this iconic amp be without amazing Reverb? Not to fret, the KING SNAKE has ‘Verb... miles of it! And it’s all about vintage. We’ve voiced the all-tube, three-spring, long tank Reverb to include just the right amount of old school vibe.

  • Page 9 A/B switching can work in a small window of settings, there are MANY more settings and tonal options you’ll likely want to access where channel switching won’t work well. While this is possible at certain settings, the KING SNAKE is not set-up for Chan- nel Switching operation due to its optimization for a single channel platform.

    Rear Panel PRESENCE choices, you will be able to achieve almost any style and tonal characteristic you wish. NOTE: The King Snake has SUBSTANTIAL BASS. One other important rule or scheme to follow is this; As the VOLUME (1 & 2) goes up, the BASS should come down.

    The KING SNAKE is one of the world’s warmest, fattest sounding amps and we encourage you to spend some time to learning the “give and take” skills needed to arrive at a well blended Tone with this huge sounding little amp. Once you spend some time, it will become second nature and you’ll be able to radically shape your sound, swap instruments, switch musical styles and craft truly in-...

    POWER ™ POWER: This switch delivers the A.C. power to the KING SNAKE. Make sure the unit is grounded (all three terminals of the A.C. TUBE GUIDE 4 x 6L6 power cord must be connected to avoid injury to the user as well as to the unit) and that the proper voltage is present.
  • Page 15: Fuse

    PENDING NOTE: As the knobs used on the Rear Panel of the KING SNAKE are not numbered like those used on the Front Panel and use in- stead a white line as a pointer/indicator, throughout the Rear Panel Section of this guide we will use Clock Face settings (9:00–12:00, etc.) instead of numbers (9.0–12.0, etc.) to describe settings.
  • Page 16: Send/Return (Effects Loop)

    The EFFECTS LOOP SEND and RETURN provides an interface for effects process- ing between the preamp and the power section of the KING SNAKE. The jacks are switching type, meaning that when no plugs are inserted, the EFFECTS LOOP is bypassed. The Loop is wired in SERIES with the dry signal and therefor you will...

    While the KING SNAKE is capable of tolerating mis- matches in the high direction (i.e. 16 Ohm Speaker/Load on the 8 Ohm jack of the KING SNAKE), it is not BLACK FACE TUBE GUIDE able to drive a 2 Ohm load without stressing the Tubes and Transformer.
  • Page 18 To use two external 16 Ohm cabinets (i.e. two 4x12 cabinets–each with 4x16 Ohm speakers wired Series Parallel), connect them to a “Y” cable or box and connect the “Y” to the 8 OHM Speaker jack. This scheme will provide a good impedance match as well. Consult the Speaker Impedance Matching &...

  • Page 22: Diagnosing Tube Problems

    TUBE NOISE & MICROPHONICS: You may occasionally experience some form of tube noise or microphonics. Certainly no cause for alarm, this quirky behavior comes with the territory and the Tone. Much like changing a light bulb, you don’t need a technician to cure these types of minor user serviceable annoyances and in fact, you’ll be amazed at how easy it is to cure tube problems...by simply swapping out a pre-amp or power tube! First may we suggest that you set the amplifier up on something so that you can get to the tubes comfortably without having to bend...
  • Page 23 DIAGNOSING PRE-AMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes.
  • Page 24: Speaker Impedance Matching And Hookup Guide

    MESA/Boogie amplifiers can handle 4 and 8 ohms effectively. Never run below 4 ohms in a tube amplifier unless you are absolutely certain that the system can handle it properly; this can cause damage to the Output transformer. A few amplifiers can handle 2 ohms effectively without damaging them ( for example the MESA’S Bass 400+ ).
  • Page 25 SPEAKER IMPEDANCE MATCHING & HOOK-UP GUIDE: (Continued) PARALLEL: When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in ( hooked-up ) Parallel results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really not suggested to wire different resistive load values in Parallel ( 8 and 4, 16 and 8 etc.
