Congratulations on your choice, the TUBE TONER. The engine room of this crafty combination of four different components is the four-channel, all-tube preamp. It is responsible for the extraordinary tube tone that is definitely up to professional stands. Next up is a MIDI footswitch, which is connected to the channel switching circuit. It lets you access a total of 10 MIDI program numbers located in Banks A and B, which gets the job done for a wide range of applications. The TUBE TONER is all about great tone, but we considered portability and versatility essential attributes, so we added a filtered stereo line out to put speaker simulated recording and direct-to-desk signals at your disposal. And finally, we equipped the TUBE TONER with a miniature 2 x

1.5-watt stereo poweramp so you can get in hassle-free rehearsal time and maybe write the odd tune or two at weird hours without alienating the neighbors. This small-but-very-practical amp can drive stereo headphones, hi-fi systems or conventional guitar cabinets. In addition to these four main components, you have load of other handy features at your disposal, including a stereo FX loop and variable stereo line outs. The two main channels Clean and Lead are each equipped with dedicated gain and volume controls for precision level adjustments. The bypass circuit routes your guitar signal directly to the output, which lets you set up a serial string of preamps or access combo preamps separately. This feature gives you an incredibly varied range of tonal options. If you´re thinking about using the TUBE TONER in a rig powered by a stereo tube power amp, the 840 might be just what you need, or if you want to go for a truly modern rig, the 930/60 (930/120) is equipped with a bunch of sound shaping features you won´t find anywhere else - some even claim that this power amp works with something akin to sonic sorcery. This Tube Toner is defined by the effort and materials that went into it: intelligent design features, superior craftsmanship, impeccable finishing and quality components. However keep in mind, that a few precautions will radically extend tube life (see handling and care guidness). The entire -Team would like to thank you for your faith in our product; we hope you derive a great deal of joy and satisfaction from your TUBE TONER. PLEASE NOTE: Read the Operator's Manual carefully and thoroughly, especially the Handling and Care section as well as the guidelines in bold-face type. Avoid operating errors and potential damage to the TUBE TONER by heeding the guidelines and cautionary remarks in this manual. The boxes shaded in gray located between the diverse descriptions of the amp´s functions contain interesting tips covering the preceding function.

Front (actually, top) panel control features:

The page 12 includes the front and rear panel diagrams.

CLEAN GAIN

Input sensitivity control for the Clean Channel and for the Crunch Channel. Gain settings depend on what type of pickups are installed in your guitar. The recommended setting for humbuckers or active pickups lies between the 10 and 1 o’clock positions and 12 to 3 o’clock for single coils for a pure clean response.

BRIGHT

Alters the EQ by boosting the upper treble range (above 2 kHz) in the Clean Channel and the Crunch Channel. Effectiveness decreases at higher Clean Gain (1) settings. For a crisp glassy tone, set the Bright switch to the On position. This setting boosts the treble response of muddy pickups.

LEAD GAIN

Gain control for both Lead channels, controls the amount of distortion in the Lead mode.

CAUTION: Extremely high gain and volume

levels in the Lead mode can produce strong feedback. Avoid feedback squeals, they lead to hearing loss and damaged speakers!

BASS

Bottom end voicing control of the preamp. To get an idea of the Tube Toner's sound capabilities, we suggest you set the tone control pots Bass (4), Middle (5) and Treble (6) to the 12 o'clock position.

MIDDLE

Mid-range voicing control of the preamp.

TREBLE

Upper-range voicing control of the preamp.

LEAD PRESENCE

Special treble control only for the Soft Lead and the Heavy Lead mode. This control is important when operating the Tube toner in combination with a poweramp that does not feature a Presence control: Set the Treble pot between the 7 and 12 o´clocks position it suppresses the gritty upper frequencies.

CLEAN VOLUME

Volume control for the Clean Channel and the Crunch Channel.

LEAD VOLUME

Volume control for the Soft Lead Channel and the Heavy Lead Channel.

POWER

AC power on/off.

CLEAN, MIDI 1/6

When you press this button, the Tube Toner Clean channel is activated and a program change message is routed via the MIDI OUT jack (19) to select MIDI Program Number 1 in Bank A or Number 6 in Bank B. The Clean channel is the default setting when you power the amp up. The red LED located above the button illuminates to indicate that the Clean channel is active. If you have a MIDI multi-effects processor handy, you can also use the Tube Toner as a MIDI control unit: When you switch channels, a discrete MIDI program location number is routed to the MIDI output jack. You can activate five program locations in each bank, which in turn lets you activate each channel with a combination of two different effects (e.g. Clean/Bank A with reverb and Clean/Bank B with chorus and so forth)

CRUNCH, MIDI 2/7

When you press this button, the Crunch channel is activated and a program change message is routed via the MIDI OUT jack (19) to select MIDI Program Number 2 in Bank A or Number 7 in Bank B. The red LED located above the button illuminates to indicate that the Crunch channel is active.

SOFT LEAD, MIDI 3/8

When you press this button, the Soft Lead channel is activated and a program change message is routed via the MIDI OUT jack (19) to select MIDI Program Number 3 in Bank A or Number 8 in Bank B. The red LED located above the button illuminates to indicate that the Soft Lead channel is active.

HEAVY LEAD, MIDI 4/9

When you press this button, the Heavy Lead channel is activated and a program change message is routed via the MIDI OUT jack (19) to select MIDI Program Number 4 in Bank A or Number 9 in Bank B. The red LED located above the button illuminates to indicate that the Heavy Lead channel is active.

BYPASS, MIDI 5/10

This circuit is pretty much self-explanatory: the input signal simply bypasses the preamp. When you activate Bypass, the input signal is routed directly to the "Instrument Output" (30) jack as well as the "Mono Output" (29) jack. The LED located above the button illuminates when the bypass circuit is active. The following program change messages are sent via the MIDI OUT (19) jack when this button pressed: MIDI Program Location Number 5 in Bank A or Number 10 in Bank B. Note: When Bypass is active, all control features (1) through (9) as well as the Bright button (2) are disabled!
