The Reliability of my Boss Katana Artist is...Shocking!

Re: The Reliability of my Boss Katana Artist is...Shocking!

The new V.2 series introduces some subtle, but really nice updates to the software and onboard control options. Patches on the V.2 aren't backwards compatible, from what I understand, but that's not a big loss, as there's tons out there for the V.1 and most users create their own regardless. Plus, V.1 patches are compatible with the V.2 if you ever decide to upgrade. If you haven't done so already, take a look at Juca Nery's patches: https://jucaneryguitar.com/product/premium/

As for the V.1 Artist vs the 100, there really aren't any differences in terms of software, etc. You're basically spending 30% more for a 10% improvement in sound (better speaker/larger cab) and a 20% improvement in usability with the controls being on the front, plus a cabinet resonance knob, which is kinda cool. For me, it was worth it and if I buy a V.2 at some point, I will get an Artist again.

Of course, that depends on how Boss treats me this time around. Their first response was very generic, so I wrote them back with increased concern for the "safety hazard" that this electric shock presents. Waiting to hear back again.

On the plus side, I'm seeing used V.1 Artists breaking the $400 shipped price barrier with a GA-FC footswitch included (which is normally $100+ on its own and can be used with the V.2 later on).

Thanks for the info, since I have a pretty much brand new Avatar 1-12 cab here sounds like the head would be the way to go if I decide to grab a Katana.
 
Re: The Reliability of my Boss Katana Artist is...Shocking!

The head is awesome. If I still had a 2x12 cab, I would have gone that route for sure.
 
Re: The Reliability of my Boss Katana Artist is...Shocking!

My boss gt10 shocks me unless its grounded by connecting to something in some way like usb or another amp that has a three prong plug.

If you have a multimeter around I'd suggest just check the continuity between the ground pin of the power cable plug & and the amp chassis or intrument cable plug sleeve or guitar strings. It might be simpler fix than having to transport it for warranty repair.

I keep saying that
but everyone ignores me
and post the same thing
in different wording

hmmm

Me thinks I may be on someone's ignore list

Not at all!

Just checked...I'm getting continuity between the ground lug on the plug and the amp chassis mounting bolts (the only exposed, non-painted metal parts), as well as the input jack casing on the front.

No continuity between the ground and power lugs or the power lugs and anything else that I can reach without opening it up.
 
Re: The Reliability of my Boss Katana Artist is...Shocking!

then the chassis should be sending the "shock" to ground not you

are the grounds in your house ok?

Now who's not reading the other's posts? ha ha!

Yes, everything in the house seems to check out fine. I haven't had any problems with any other devices, all outlets check out electrically and for grounding, and the shock was still happening when I tried the amp on different circuits in the house. The house was built in the '90s, so no wonky wiring, etc.

Interestingly, when I was playing it today, it wasn't shocking me. Makes me wonder if there is a loose ground internally or if the ground plug is experiencing an intermittent failure. If so, that could explain the continuity, which I just checked today, as well. If it starts shocking me again, I'll try to check the continuity again.

Still waiting to hear back from Roland/Boss. I'm about to send a second follow-up email.
 
Re: The Reliability of my Boss Katana Artist is...Shocking!

Try this

Shuffle your feet around where you play at for just a bit
Then touch the amp

You could be building a static charge not recieving one

The longer you do this the bigger the charge gets

I have some shoes that cause the door knob to bite the fk out of me here at the house

It may be the static charge escaping to ground
 
Re: The Reliability of my Boss Katana Artist is...Shocking!

Yeah, I thought about that, too, but that's not the case.

In my initial testing, thinking it could possibly be static, I would first touch the guitar and amp chassis, then intentionally stand there without moving, waiting for 20-30 seconds before I touched the amp or metal parts of the guitar again. I did it with shoes on and off.

I could repeatedly shock myself without moving and the longer I waited, the stronger the zap was. If it was just static, it should be a single zap and done unless I were to move again.

Sounds like a faulty ground connection in the amp. If its the only amp from your collection doing it then its isolated to it. These amps have usb/micro usb slots for updating firmware? If it has then connect it to your pc or laptop, no need to turn it on, it just needs to be plugged into the wall with a 3pin plug. If the amp has a faulty ground somewhere then the usb cable would give a path for it to ground through the laptop.

Sometimes other devices like water heaters, ac, fridge can cause such problems too by dumping dc, its rare though but worth investigating if you have free time, to turn on one device at a time in the house to see if any offenders are present.

I so hate sending large items for repairs, I remember my first valve amp being stuck for 5mnths at the shop for repairs, the wait was agonising.

That would be considered a safety issue, and Boss should know about it, and they should take care of it. And getting it to work in the house by hooking it to something else is one thing, but then you might have to play it at a gig, and clubs always have great grounding, right?

This is something I would get fixed.

Speaking of, have you heard anything back from Boss yet?

I would probably not wait on an e-mail, in the old days we used these things called telephones - https://www.yellowpages.com/los-angeles-ca/mip/roland-corp-7098293?lid=7098293

^Yeah, but grounds on a pcb board in an amp like this won't just break in between somewhere. There are two stress points that could have issue, the input socket/fx send-return or the power plug inputs. The power socket is easier to fix, the other three sockets if they have a problem then a reflow of solder at the pads may fix it. These sockets are held tight to the chassis with a nut, the pads are less likey to lift off. The electric shock being experienced is in DC form here for now, if it were from the mains then :omg:

A quick look under the hood since its out of warranty wouldnt hurt.

Only thing I'm going to say is I'd stop using it, in case whatever it is will get suddenly worse; if it's something coming loose, when it falls off it might get MUCH worse.
