Footswitch

The TBFS-4 footswitch allows for remote control of 4 features on the TB–1200/600 amplifiers: OVERDRIVE, VARI‑Q™, FX LOOP/BOOST, and TUNER. When the footswitch is connected properly, "On" will be visible in the display. To activate OVERDRIVE, VARI-Q™, or FX LOOP/BOOST, press and release the corresponding button (the LED will turn red indicating the function is active). A volume boost can be achieved by adjusting the TRIM control clockwise (located on the rear of the amplifier, see page 7, item II) and activating the FX LOOP/BOOST button. Note: The front panel buttons on the amplifier may still be used when the footswitch is connected.

To activate the TUNER, press and hold the button for about 1 second. The amplifier will be muted (all outputs except TUNER OUTPUT) and the front panel MUTE LED will flash. When a signal is detected, the nearest note is shown in the footswitch display and one of the four red LEDs will flash indicating sharp or flat. The inner two red LEDs indicate the note is closer to being in tune while the green LED in the middle indicates in tune. If a signal is not detected for a few seconds, "---" will be shown in the display. Press and release TUNER button again to exit the tuning function and resume playing. All other footswitch and front panel function buttons have no effect while the tuner is active.

Tube Replacement

Two 12AX7 dual triode vacuum tubes (valves) are at the core of your TB-1200/600 amplifier. Typically a 12AX7 tube will last several years, but through heavy use and frequent transportation jarring, it is possible to have a tube last less than a year.

When to replace the preamp tube: Sometimes, tubes become noisy or “microphonic” (the amp sounds like a glass chime tinkling during certain notes) as they wear out, but other times, tubes will fail without warning. If your amplifier stops working and other possible causes have been eliminated (breakers, cords, etc.), have an authorized service center inspect your amplifier for tube failure.

Rack Mounting

For Rack Mount Units Only:

TB-1200/600

The TB-1200/600 can be mounted in a rack

or flight case that measures anywhere from

 

13" (33.0 cm) to 17.5" (44.5 cm) between

 

front and rear rails.

 

1) Remove the adhesive rubber feet from the bottom of the TB-1200/600.

2)Remove the 2 bolts {S} on each side of the TB‑1200/600, then use them to loosely attach the “rack ear” brackets {R} that were supplied with your TB‑1200/600.

3) Lift the TB-1200/600 into position and provide temporary support until all corners are attached.

4) Bolt the TB-1200/600 front panel tabs to the front rack rails (NOT SHOWN).

5)Slide the adjustable brackets {R} to fit the rack, then attach with bolts through the rear rails {Q} as shown.
