Mesa Subway D-350!

When they fix the "Hum" problem. I have had 2 of these in the UK. Amps both work fine with my active basses, but with passive bass or my active basses switched to passive, there is a "Hum" when the guitar volume control is backed off from full. Mesa say they couldn't recreate the problem with the first amp when it was sent back to them. The USA store say they did have the problem on the amp when it was sent back to them, and they sent it back to Mesa. The store tested a second amp which was fine, but when I tried that in the UK, it had the same "Hum" problem as the original. All has now gone quiet from Mesa/Store and I am using the second amp in the UK with my active basses.
I have to say apart from the "Hum" issue, the amp is great and because I don't use passive mode on my basses, it has become my first call amp...D800 is now spare and or used for louder gigs.
All cables/mains checked.....the Hum issue doesn't happen with my D800 ot D800+ di.
D800+ di fed to the aux in on the D350 is also fine, suggesting a D350 input/preamp problem.

Are you saying that Mesa has acknowledged there is some general "hum problem" as you described and stated that the D-350 won't be available in Europe until they fix it? Because that's what your post implies, and if that's not the case your post is misleading.

No, we have not been able to recreate the problem on the amp that was returned on ANY of the multiple basses we have tried, on 120V, 230V, 50Hz or 60Hz.

The amps will be available in Europe when we resume shipping globally. We are finally starting to catch up on the overwhelming backorders.

I figured all of the above was the case. I understand that maybe the issue is frustrating for the user, but (a) it doesn't sound to me like an amp problem; and (b) certainly doesn't seem like the cause of low availability in Europe.
 
The fact that you have tried not just one, but two of these amps and you still have a hum when no one else can replicate it even with those same exact 2 amps suggests something else is going on in your system and is not an amp issue. I have some passive basses as well as active ones and you can hear a pin drop in my bedroom when the amp is on with all my basses. Good luck getting to the root of the problem.

No, Mesa have not acknowledged Hum problem from what I've been told and I didn't say they had acknowledged it. I said they couldn't replicate the problem. I would say the probability of 2 faulty amps with the same issue extremely unlikely. The issue doesn't happen on other amps I have tried and same cables/speakers work fine and of good quality. 3 Sadowsky's, an Xotic, a Maruszczyk, a Fender and a Gibson jazz guitar have all exhibited this issue. Also been to many different venues, so different mains sources. My D800 and D800+ di are all good with passive basses.
Does anyone else have a D350 they've brought over to Europe, if so is it working ok with passive basses?

My point was simply that you heavily inferred these amps weren’t available in Europe because of your issue, which is misleading. I’m sorry you are experiencing trouble.

Check to see if your strings are grounded and your bridge Also if you are using coated strings you will not provide the grounding needed to keep the hummm down. There is a ground wire in the control cavity that runs to the bridge. So touch the bridge to see if the hump goes down. Coded strings can insulate your fingers from the strings. And also from the strings to the bridge. There is a discussion of this with Sadowski and Mike Tobias in YouTube

Soooo .... working with the kid I'm managing and producing I learned the D350 and a Hartke HD115 makes a pretty darn good guitar amp in a pinch. Ran my acoustic into it thru a DD7 and RC3, and my Les Paul thru an Atomic Brain, SC2 OD, DD7 into the looper. Don't have a pickup in my mandolin yet or it would've had a run, too.

Talk about versatile. :laugh::hyper::bassist:

I know of a couple of players that switch off between bass and guitar using the D-350 and a Subway cab with the tweeter turned down. One guy uses guitar pedal preamp, FX and O/D pedal for guitar, then bypasses them for bass.

There are many ways to skin that cat.
