to go for vintage tube tone and for playing solos. This sound character is ideally suited to push your guitar

Write / Copy
Press this button to store the modified setting of a programmable feature to a MIDI memory slot (gene-
rally called a preset). Here‘s how to distinguish between WRITE and COPY: with the former you‘re actually
programming or writing a new MIDI preset, with the latter you‘re making an exact duplicate of an existing
preset. The system will select a WRITE operation whenever you edit a MIDI preset, that is, when you have
modified a programmable feature. You‘ll know that this is the case because the Status LED flashes steadily
when you edit one or several programmable features. If you press the button and did not edit a MIDI preset,
the system will select. This means that the given preset becomes the source, and its contents are dumped
to another preset and stored there. When you press this button, the Status LED lights up continuously to
indicate is activated. The system quits mode autonomously if you do not select a new MIDI preset within
about 30 seconds. The preset programming process -- the WRITE command, that is -- is not carried out as
soon as you press the button. Pressing the button merely initiates the process. You must hold it down for
about a second until the Status LED flashes three times in rapid succession. This mechanism is designed to
prevent inadvertent programming. You can cancel the programming process at any time before the Status
LED first illuminates by releasing the WRITE button. Again, the preset will only be programmed successfully
if you press and hold the button until the Status LED flashes three times.
You‘ll have to go through a similar routine to copy a preset once you select a target preset: When the Status
LED extinguishes, the copy operation is underway and can no longer be cancelled. The LED flashes three
times to indicate the preset was copied successfully. You can cancel the copy operation by releasing the
key, but only for as long as the LED lights up continuously.
