On my powered Kabinet that LED is simply the power-on indicator. It may change color if overdriven, but I've never played it loud enough to find out.

All I can say about a Kone in an open back cabinet is that my drummer hated the backwash from it. Switched to a PowerKab and everything has been fine.

Rather than re-shuffling the DSP code I would have opted for switching actual caps in and out with small relays. That would be virtually instantaneous in both directions.

If you are bench and software savvy it wouldn't be rocket science to use a MIDI-controlled relay to shunt a cap across the input for authentic behavior. I was going to do this but found a stage in the interim.

I don’t think it’s only available to OEMs.

The trick is finding a dealer who stocks it.

In the States, if Parts Express doesn’t have it (or can’t get it)……¯\_(ツ)_/¯

I haven't checked recently, but last time around they simply didn't stock that model. It was available only from a seller in Italy and at an inflated price.

Tried out the arrangement at a studio jam last night and it worked really well.

Only slight downside is about ½-1 second latency changing patches with the remote. Don't remember having that issue set up at home. Will have to investigate further.

For the future I want to minimize the hardware needed for the setup. Currently I have a 4 way extension, the 8 port switch, the switch power supply and the wifi access point all screwed to a wood board. Would like to make it a lot smaller. most of the space is taken up by the 4-way 240v extension and the switch and it's power supply.

So has anyone used a PoE passthrough 1 to 2 port switch/connector to utilize the PoE from the Kemper to connect the Acces Point and the remote to?

I do generally see a lagging response to the first patch change, but then it picks right up.

Last I checked the official Kemper IcePower amp is available only to OEM customers. Has that changed?

I fought a long-running battle with disconnects when using an external access point with my Kemper Rack. It turned out to be an issue with power supply to the little portable router I used. It came with a wall-wart supply, but I didn't have room on the plug strip so I used USB charging outputs on that strip for power. I should have read the specs on the wall-wart. The AP requires a 3A supply and plug strip was rated at 2A. It was constantly resetting due to low voltage...

How do you use the Kemper if not in the PA ?

The old fashioned way: Run the monitor output into an amplification system behind you on stage. My band gigs regularly across Vermont and New Hampshire. 99.8% of the rooms are too small to even consider miking instruments. We just play off the stage using restraint and run only vocals through the FOH (and stage monitors). Works out well and we receive many compliments on the sound. I use a Kemper PowerKabinet, but there are dozens of setups that can do the trick.

I used a Kone in one of the Mojotone open-back cabs a year back. Sounded great, but my drummer was getting blasted with sound from the rear of the system. Moved to a powered Kabinet and all's well.

Even after watching all available videos and endless tinkering I was never able to configure "clean sense" to actually get softer when I back off volume on the guitar. However, the Beta 11 code actually does support this when "clean compensation" is dialed to minimum. I no longer feel like I'm fighting with the volume leveling.

Unfortunately, my setup became plagued with random disconnects and I had to drop back to a lightning/ethernet adapter on the iPad and cabled connection. Recently I picked up a Stage and have had no disconnect issues.

I've had one open since the day I started this thread. As I mention above, they told me it's expected. But it doesn't match your experience nor can I believe they would have shipped software that took many seconds to bypass the effect. I pinged them again on the issue but I have not heard back.

Thanks very much for confirming what I suspect. The delay I'm seeing is unlikely to be intentional or expected. I can tolerate a short glitch before and after soloing, but having to wait many seconds before the fuzz bypasses is a non-starter.

Does it clean up that quickly when you tap the button again for bypass? I'm only seeing it in that direction. It turns on with minimal interruption and off painfully slow.

I reported the problem to Kemper support who tell me this is normal behavior. From the manual section on the Kemper Fuzz:

You will notice an audio drop-out when switching, too. This drop-out will also occur whenever you switch from or to a Rig with a fuzz with active “True Impedance”. This drop-out cannot be avoided as the hardware impedance dramatically changes the incoming level of your guitar in an instance. Consider carefully whether you will make use of the volume pot advantages or benefit from an artifact-free switching.

What threw me is that it's not really a "drop-out". The impedance changes instantly, brightening up the sound, but the fuzz effect does not bypass for almost four seconds. This all seems a bit odd, but not being privy to the system architecture there may well be good reasons for it.

Subject says it. The original Vox / Dunlap wah pedals have a rather low input impedance and it's part of the characteristic sound. Can we get a checkbox in the wah blocks, please?

I just switched over from a rack profiler to a new stage unit. The True Impedance option sounds quite nice on the Kemper fuzz, but it's behaving very strangely when I turn that block off using a footswitch. The impedance setting changes immediately (I can hear the sound get brighter), but the fuzz does not get bypassed for another four or five seconds! If I disable the impedance check-box the effect bypasses immediately on press of the footswitch. Anyone else seeing the problem? I already tried a factory reset and restore, but no change in the behavior.

Some of those little molded inline switches use extremely thin wire and might cause enough voltage drop to be a problem. I just went through this while setting up a RaspberryPi based computer. With the power supply (USB) plugged directly in it worked fine. With the switch (looks very similar to the one in the photo) in line it crashes repeatedly. Digital devices can be intolerant of marginal power.

In one of my bands I found the rear wash from an open back cabinet caused problems on stage. After a lot of complaints from the drummer I switched to a real powered Kabinet. No more issues.
