A tip from the designer:

:

MIDI preset 1 activates when the amp is powered up. If you want to edit and/or store

other MIDI presets, you must connect a MIDI foot board or another MIDI send device

to the

port (33) and use this outboard device to select the desired MIDI preset

on the amp.

Note that the Status LED also indicates the status of components unrelated to

and

. The microcontroller runs a short system check after you switch the amp on.

Should it find a defect in the memory chip (EEPROM), the LED

Press the Write/Copy copy button to confirm that you got the message. Once you have

done this, the system will be ready to run, although you may encounter problems

when attempting to select or store MIDI preset.

The Status LED serves a third display function. As described in section 53 on page 20

and page 23, it indicates that no speaker is connected to the power amp outputs.

This knob determines the Lead I channel's input sensitivity and preamp saturation

level.

Extremely high gain and volume levels in Lead mode can produce powerful

feedback. Avoid feedback squeals; they can lead to hearing loss and damage

speakers! At higher volumes, back off the Gain, Treble and Presence levels in order to

prevent unchecked feedback!

The two Lead channels' fundamental tones are not worlds apart:

boasts slightly

less gain and bottom end, but its speedier response makes it a great choice for brisk

riffing and lightning lead runs. The Lead I channel is voiced with scooped mids, making

it an excellent choice for dialing in hip heavy metal sounds.

This knob determines the Lead II channel's input sensitivity and preamp saturation

level.

Extremely high gain and volume levels in Lead mode can produce powerful

feedback. Avoid feedback squeals; they can lead to hearing loss and damage

speakers! At higher volumes, back off the Gain, Treble and Presence levels in order to

prevent unchecked feedback!

The two Lead channels' fundamental tones are not worlds apart:

boasts a bit

more gain and bottom end than

, and works very well for fat, in-your-face solos

and chunky riffs with a big bottom end with plenty of low-frequency punch. Its

response is not quite as speedy as

, and the low-end can turn muddy at high

Gain settings in combination with high-testosterone pickups. Note that certain

midrange frequencies are boosted in the Lead II channel for a punchier tone, ensuring

your lead lines cut through.
