Switchblade
FACTORY SETTING: MIDI CHANNEL = 1, OMNI = ON
Note: OMNI ON is helpful if you are unsure via which channel
a connected MIDI device sends its messages.
During the MIDI setup routine, the LEDs that normally indicate the
preamp Channel indicate the MIDI Channel. The following table MIDI
Channel lists the MIDI Channel settings in what is called binary code:

Press and hold SERIAL for a few moments to quit the MIDI setup
routine and store the settings. The amp returns to its most recent
operating status (normal mode).
6.3 Factory Settings and Factory Reset
A factory reset is a seldom needed feature. Nevertheless, be sure to
read the explanation carefully to ensure you don't accidentally delete
your presets.
6.3.1 Triggering a Factory Reset
If you press STORE and FX SERIAL
amp, all settings are reset, including the 128 MIDI-switchable presets
and the basic MIDI configuration.
6.3.2 Factory Presets and Basic MIDI Configuration
The Switchblade is delivered ex-factory with 64 different presets
(memory slots 1-64). In the memory slots 65-125 you will find copies
of the first 64 presets. You may find a list of all the presets on the
accompanying sheet.
The basic MIDI configuration is:
• • MIDI Channel: 1
OMNI ON
• •
FX ON is switched off.
Caution: This procedure is a last-resort option! It irrevocably wipes out
all stored settings.

SERIAL is deactivated.

6.4 Storing Settings/Programming

You have two options for storing a preset to one of the 128 memory
slots: Select a new memory slot via MIDI (6.4.1) or overwrite the
preset directly at the device (6.4.2).
6.4.1 Selecting a New Memory Slot via MIDI Learn
• Press the
STORE button briefly; it lights up to signify that it is armed
(MIDI Learn).
• Select a MIDI bank from 1 to 32 on the FSM 432; it flashes to signify
that the FSM 432 is waiting for input via one of the four preset
buttons A to D.
• Engage preset button A,B,C or D; the board stops flashing, the light
on the STORE button extinguishes, and the preset is stored.
Caution: When the FSM 432 is in DIRECT MODE (see chapter 6.1.2),
a BANK UP/DOWN command also triggers the storage process! We
recommend deactivating Direct Mode when programming to prevent
inadvertent overwriting of presets.
Note: Here's how to proceed for other manufacturers' MIDI boards
and MIDI-enables devices: Arm SWITCHBLADE by engaging the
STORE button and selecting the desired memory slot. As soon as
SWITCHBLADE receives a valid program change command, the STORE
button extinguishes and the preset is stored.
If an error occurs (the amp remains armed), you can cancel the storage
process by pressing STORE again.
6.4.2 Overwriting Presets Directly at the Device
There is an easier way to overwrite the most recently selected preset
than going from the amp to the MIDI board and back after every edit:
Press and hold the STORE button until its light extinguishes (after
about two seconds). The ORIGINAL VALUE
flash to confirm. Then you can release the
settings are stored.
7 Replacing Tubes, Service
and Preventive Maintenance
SWITCHBLADE is factory-loaded with EL34 and 12AX7 tubes. Once
they've been burned in – that is, operated continuously under a load –they
are subjected to a rigorous selection process. Their electrical specs and
mechanical status (microphonics) are checked, and then they are installed
in an amp and their sonic performance is auditioned. One of the most
important steps in this process is tube matching, whereby tubes with the
same characteristics are teamed up in matched sets of power tubes.
When to Replace Tubes
The tubes in SWITCHBLADE are exemplary in terms of quality,
workman-ship and long service life. Nonetheless, tubes show definite
signs of wear when their service life is nearing its end. Telltale signs are
increased microphonics, noise and hiss, muddier tone through loss of
high-end frequencies, degraded performance, etc. Take these indications
seriously and replace old tubes. Not only do these side effects take their
toll on sound quality, they also indicate the aging tube will soon fail!
