    Kemper profiler (unpowered) rack and remote, in a flight case. £1325 ono.

    Unit is in excellent condition, loaded with many stunning profiles & effects.

    The protective coating is still on the displays of both units.


    Includes two Ethernet cables (unit uses one, and one is a spare).


    It's in excellent condition, kept in smoke free environment. Use for several months.


    I'm selling the two units as a job lot and am not willing to split.


    Collection preferred, as it's a heavy package, from South Liverpool, UK.

    (I'll post for £20, as it's quite heavy in the flight case)


    If you are within a reasonable distance of Liverpool, I'm OK to meet up and deliver.


    Payment on collection.


    If you want to sort out your own courier or collection, that's fine, as long as your courier pays me when they collect.


    Any questions, give me a call.

    I'm getting confused. On the basis that it may be a faulty USB stick, I formatted another stick MS-Dos fat32, and tried again. I now get a message "Invalid file". I am using the kaos.bin file.

    If I turn on the unit (Unpowered rack) without a USB in it, it displays, 'ERROR: unable to mount device. With a USB in, it displays the 'booting and burning from USB device'.

    The OS on the stick is PROFILER Operating System 7.4.1.17821.


    Nothing is happening, clearly. It's not booting and burning.

    I was updating the unit and accidentally pulled out the USB drive.


    After research online, I concluded that I have probably corrupted the unit's OS, so have followed the following steps. However, the unit has been displaying "Booting & burning from USB drive" for an hour or more, so I am thinking nothing is actually happening?


    Can one of the Kemper technicians give an approximate time for how long the 'booting & burning process' should take? Before I conclude 'nothing' is happening, and I need alternative correction advice.



    1. Download the latest Kemper Profiling Amp firmware
    2. Transfer the “kaos.bin” file to a USB flash drive
    3. Plug the USB drive into the Profiling Amp
    4. Press and hold the < and > keys and switch the amp to Tuner mode
    5. Wait until the firmware has been reinstalled

    Hi, With regard to 'Booting and burning from USB', can someone tell me how long this process takes?

    I'm trying to assess if the unit is actually doing something or not.

    It's been a few hours now and it's still telling me that's what it's doing. Thanks
