New GK Plex Preamp

[The Rage]

Ok, tried two passive Harley Benton and the hum/buz is here.

I can't speak for MattF007, but in my case, the hum/buzz was there even with no cable connected to the input.

With no cable in the input, mine is still silent

It went away whenever I grounded the Plex. For example, by connecting the Amp out or the DI out to a piece of equipment, which resulted in the ground shield of the TS or XLR connector to be connected to ground. Or, even better, by touching the Plex and the protective earth contact on the mains outlet at the same time with my hands (make sure you know what you're doing -- only touch contacts that are exposed by themselves, like on many central European outlet types, only those are meant to be touched without bodily harm).

Yes.
With one bass I've touched the chassis of the plex and the hum is gone, but with another the hum is just lower. It goes away when I touch one of the screws on the bottom (under "overdrive" and "compressor/tuner"). If i tap one of the screws, kt does a clicky noise.

Quick question, I have the plex for about 2 years now, and my footswitches have stopped working properly.
The comp/tuner footswitch it's next to unusable working lets say every 30 pushes and the drive footswitch worked properly till last week when it started to become really annoying, having to click it 3-4 times to work.
Has anybody encountered this and how can I fix it since I dont have the warranty. Will a tech be able to solve it if it's a contact problem or due to the pedal's nature repairs like this are not possbile from non GK authorized dealers/ techs.
Cheers

Hi there,
I would contact GK directly. Even though it's out of warranty they usually have great customer service. @rag
Best wishes

^ +1
that'd be the first thing, to call them

 

[CrossRO]

Will do that most likely through email, since I am living in Romania and its quite finicky.

Even so, I’d bet money they will do their best to sort it out. Good luck with it!

Just got a response, they can adress it, yey, finnally will be able to use the tuner again
Any news on the "new" update?

Well you got an answer from them, ask them!

I'm wondering about this as well. It's been over three years since the last firmware update.

Hey - this thread can be a bit hard to follow. Are there any issues with ground hum through the DI? I can't properly test mine until I can run it through a sound system at a gig, which may be months away yet.

i did not experience any ground gum issues going straight to the board from the Plex a couple of gigs.

Ground gum is the WORST....

None with mine when I had it, there's a lift if you need it.

 

[Andyman001]

I use mine every week @ my Church gig and also no hum.
That being said, in my understanding the issue is using headphones ONLY, as it has no ground path.

True.
Took me about an hour of agitation and thinking my PLEX was defective before I figured it out that the hum stopped when the cab was in the chain.

I think it's time to sell mine. It's been doing nothing more than being an expensive headphone amp. I had high hopes, but fairwinds and following seas.

This is what I plan on using my Plex for...

It's a preamp with compression, EQ, and overdrive, and a loop if I want it; I take that signal and send it to the Rolls, which will have my bass signal, a monitor send (line input), and a Mic input for ambient sound, all of which will be sent to ME via my fancy Westone IEMs. XLR to the house, Inst Out (from the Rolls) to an amp if necessary but hopefully not.

All of this so I can ALWAYS hear myself, control how much of what I hear, and protect my hearing in the process. I sit when I play, so I can keep this on my left side, out of my elbow's way.

The "ambient sound" thing is so I can hear a little bit of what's going on in the open air around me ("Hey, we're changing the set list" or "Can you guys play 'Freebird'?"). There's gotta be a good cheap mic that will suit this purpose, like an SM57 knockoff...

I've been reading some of this thread but I can't keep up with 100+ pages.
What was the update that everyone seemed to be waiting for, and the lack of which has brought many to sell their Plex?
