    Im happily running v6 firmware and its been serving me well (touch wood)

    In the past i’ve updated with each public release that came along but i get the impression that v7 was a big release with some significant additional functionality mainly to accommodate the stage floor-unit. But, I regularly read of issues and bugs being reported and fixed and wonder if i am as well to continue with my v6. It’s obvious the kpa OS is becoming more and more complex to deal with the new hardware and new software features (rig manager, kone, new menu-sorting etc) Only today, i read of some removed functionality (external switch polarity option) perhaps in a quest to streamline/simplify the OS.

    Kemper are great at dealing with issues and keeping us up to date and I appreciate theres likely to be many silent users (the forum voyeurs) that run the latest firmware without issues and probably never comment on these forums. Perhaps the old adage of “no news is good news” is the case here...

    This is in no way a moan or complaining post. Im just in need of some reassurance, either way.

    I’m telling myself “if its not broke dont fix (upgrade) it.”:/

    Does anyone else feel similar or maybe there’s some v7 users happily gigging and playing with nothing to add to these forums?

    I too was looking for a backup fly rig sized solution a few years ago.

    Guys here on the forums suggested to me the atomic amplifire. This as when the red three button version had just come on the market. At the time it was quite pricey but now they are going cheap second hand.

    Since then they have launched the six and twelve button versions and I cannot recommend these enough for a Kemper alternative. The effects still leave a bit to be desired, in my opinion, but the amp tones are awesome and adding your fave cab IRs does the job very nicely!


    Does anyone else here use one?

    This has been brought up numerous times over the years.

    Just search the thread history.

    Tap Tempo

    Tap button blinking irregularly

    What about this frantic TAP tempo LED?

    How to get the tempo light on the remote to flash in tempo?

    Tap Tempo blinking out of sync

    Tap Tempo not consistent after 5.7.2 update ???


    I think its safe to say if it could be fixed it would have been done by now.

    Unfortunately its something you learn to live with, a bit like hair-loss.

    Yes. The Kemper has an auto-calibration feature, so the short-circuit that briefly appears when you plug it in will tell the Kemper that the pedal is able to deliver a smaller resistance (0 ohms or so) than the toe position is able to once calibrated.

    It would be useful if the auto calibrate feature could be selectively made inactive. With certain pedals it can be a hindrance as much as its a help. (As described by musicmad ).

    pedals that have a sprung limit (perhaps a foam or rubber cushion at toe and heel limits) may also permit a greater minimum and maximum value than when at resting by taking your foot off.

    This tone control and its 1M ohm resistor is only in circuit when using the single coils, neck, neck+mid, mid, mid+bridge.

    Its deffo a 250k pot (its stamped on the casing and measures as such)

    It actually goes to the selector switch which then in turn goes to the volume pot. (i wrote on the image like that for simplicity)

    I've not compared varying the volume with/without this so cant comment on how the audio is affected.

    Follow up to the recent messages, the removal of the pot does have a noticeable affect on the tone.

    There is a 1M ohm resistor across the tone-pot from signal to earth (see image)


    Follow up to I'm not sure of the capacitor value but it's absence seems to have the biggest impact on the tone.
    So, i've had to replace the pot with some resistors in order to mount it inside the body.


    Surprised to discover the 1M ohm resistor connecting the signal to earth, though this is via the 5-way selector switch and only active on positions 1-4 (bridge position is excluded)

    i think the morph doesn't get "reset" when jumping to a new slot. It's as if the morph operates on its last instructions which get carried over into the new slot selection. Maybe its the last bit of data to get loaded and consequently will reference the "old" values until completely loaded into the working buffer?

    In hindsight, i now wonder if this was the start of the Kemper kone development.

    It would make sense (to me, anyhow) that some part of the speaker-sound algorithm was altered to make way for the implant o a speaker's response curve. I guess the kone development was underway in the early part of 2019

    Having just watched tonejunkie’s video on the kemper kone, i think back to a flaw i discovered that was, i was told, a correction (i will be slapped for labelling as such) implied by kemper that affects the sound of the cabinet block where the EQ response of all cabinets got changed. I found it odd that it took late v5 firmware before this was picked up and addressed which in my opinion has since delivered sub-standard results only when using the kpa purely for cabinet only. (The regular signal path, amp->cab still renders as expected as if part of the tone processing was moved out of the cab block into the amp block)

    With the arrival of the kone, Im now guessing this modification was in preparation for the kone, which obviously was under develpment at that time. Unless you use just the cab and nothing else you will most likely not even be aware of this change that was introduced in v5.7 firmware. I may be wrong but it bares some logic, in my opinion.

    To explain further, see the post on the issue found;

    v5.7.x Cabinet sound changed

    I don't use the Tone control on my guitar. Its always set on "10", so, would removing the pot from the circuit affect the tone in anyway?

    The pot, i'm certain, is 250k (not sure of the capacitor value) so theoretically there will be less resistance to earth and to the tone-capacitor.

    Will the results be negligible or should i install a 250k resistor and reinstate the tone-capacitor to "simulate" a tone-pot locked off at max?


    thanks for any info
