- like an all tube circuit. We salute your discriminating tastes and your obvious demand for great tone ! We would like to thank you for trusting us to build your amplifier and for choosing Mesa/Boogie as your amplifier company. We feel confident that BUSTER will exceed your expectations of performance in both live and recording environments.
OVERVIEW: (Continued) BUSTER is equipped with a buffered parallel Effects Loop with an EFFECTS BLEND Control which is located on the Rear Panel for interfacing outboard signal processors. For direct interfacing to a recording console or live mixing board, we have provided a balanced XLR DIRECT OUTPUT which is fed by the VOLUME Control. There is also a SPEAKER MUTE switch for those times when you want to go direct and don’t want to hear the speakers live.
FRONT PANEL: First familiarize yourself with the layout of the Front Panel and locate the EQ FTSW jack. This jack, when connected to your footswitch will allow you to engage the 7 Band Graphic EQ remotely. If there isn’t a footswitch available, the mini-toggle on the right side of the EQ (Front Panel) will allow you to engage the EQ manually (EQ IN).
MID: This control blends the lower midrange roundness and upper mid attack frequencies in and out of the mix. Like the TREBLE Control, it is more powerful as the pot is increased toward the top of its range. At the top of the control it becomes the domi nant tone control and the effectiveness of the TREBLE and BASS will be greatly diminished.
GRAPHIC EQ: This wide band, seven point graphic equalizer is the alternate shaping tool for BUSTERS’ dynamic pre-amp and by adding it to the already powerful rotary tone controls, virtually any sound you desire can be dialed up. The equalizer may b e assigned to affect the signal in two different ways.
STANDBY: Perfect for set breaks... this toggle switch also serves an even more important purpose. In the STANDBY position the tubes are at idle so that during power up they may warm up before being put to use. Before POWER is switched on make sure the STANDBY switch is in the Standby position.
PIN 1 BLEND HANDBUILT BY MESA/BOOGIE LTD. IN PETALUMA, CA NOTE: Euro style power cord receptacle is under this edge of chassis. FUSE: This is the A.C.’s (Alternating Current) main fuse and provides protection from outside A .C. fluctuations as well as possible power tube failure damage.
EFFECTS LOOP: SEND & RETURN (Continued) Use the FX BLEND control to blend in the desired amount of the effect you wish to use from your processor. The FX BLEND let’s you sweep between approximately 10% of the wet signal and 100% of the wet signal mixed with the dry signal.
8 OHM * 2 x 16 ohm cabs - use the two 8 ohm outputs HAND BUILT BY MESA/BOOGIE LTD. IN PETALUMA, CALIF * 1 x 16 ohm cab + 1 x 8 ohm cab - use 16 ohm cab...
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...

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.

BIAS ADJUSTMENT: (Continued) directly, you can only change it by adjusting the amount of bias VOLTAGE that goes onto the tubes’ control grids. Voltage and current are NOT the same. Current is the AMOUNT of electricity, the “quantity” — and is measured in amperes. Voltage is the degree of electric charge —...

How much money and trouble that has saved Mesa/Boogie players you couldn’t estimate. Our rigorously tested and hand selected tubes are available at your nearest Mesa/Boogie Pro Center or from us directly. Nobody offers better price, quality or warranty than we do ... so why swerve? Next time we’ll talk about our part in developing the great Sylvania STR 415 type 6 6 and how we’re on the verge of seeing something...
