I just got a Herbert in trade for my VH-4, so stoked to get back to Herby :rock: But when I plugged my MIDI controller into the head the Phantom power doesn't work :cry: :cry: I'm using the same setup that worked on my VH-4 AND the other Herbert I had... nothing different... how big of an issue is this? Can anyone chime in please? I'd be lying if I said this isn't a HUGE issue for me, trying to get this resolved ASAP. This thread is always awesome when I need some help, and I'm definitely in need of some... no sugar coating... give me the worst please...

Hoping Papa Diezel will chime in too :yes:

Just a Rocktron MIDI Mate with a Rocktron 7-pin gold connector MIDI cable... I know nothing is wrong with the cable or pedal...
 
You could have to pay up some cash. We all know the risks of buying or trading used Diezel gear, no warranties!!! Who did you end up trading with? Maybe he could help you out with the bill... just an idea. As far as being any help with this I wouldnt be of much help, but good luck to ya.
 
Thanks Buzz fucking Killington. I am the one he traded with and why do we not wait until we see what is going on with it before we jump to conclusions. I can understand why Diezel's warranty is what it is. This is the 2nd Herbert I have now had a problem with. Thats 2 for 2. This is getting ridiculous.
 
I have no doubt Chris will help me if need be, I wouldn't trade with someone whom I thought would just cut me lose as soon as the amp is shipped... that's not the issue... I just want to be pointed in the right direction before I open this thing up and go poking around, as I have no idea what I'm doing...
 
Check that the ribbon cable on the main board and back board is seated.
 
Any possibility of someone with a gut shot that can point me out as to what exactly that is? I mean I have a good idea, like I said I just want to be 100% sure/careful, thanks for the post Mark!!!

Thanks again Mark, I have her opened up, and the fuse and ribbon are extremely snug... I'm not even sure how the ribbon disconnects to be honest but as far as I can tell it's definitely attached... I'm looking at the back of the 7-pin midi input from the inside of the chassis and something looks a bit off to me... there are 4 wires hooked up to it... as opposed to 3 wires hooked up to the midi "thru" input, however, on of the small pieces of metal that the wiring is soldered to is slightly bend to the side...and looks as if its touching another wire, I'm not sure if it shouldnt be touching it... or if it is actually supposed to be soldered to it and ISNT, but it's definitely not attached... I took several pictures so you can see what I'm talking about, this may be nothing, and I had to sell my really good camera so the macro setting on my current one sucks ass, but here are the pics I'm talking about... I'm sorry for the larger photos, but as I said my camera blows... figured the larger images would help...

Picture of Fuse and Ribbon that appear to be fine...

Now the metal piece I'm talking about is the left most pot, and it's at the top/middle.. it is bent to the side, and slightly touching the wiring next to it, not sure if it SHOULDNT be touching it, or if it should be soldered TO it... or if it makes no difference whatsoever... BUT, the other metal pieces that are bent in this way, are soldered to the one next to it... aside from this one, it is bent in the same exact way, yet it isn't soldered... I'm just fishing in the dark here... I took a few pics to try and be depict it... sorry AGAIN for the quality, trust me I tried...

That center lug for the left hand Midi port should have no wire soldered to it and it should not be touching the other pin.

I just texted him saying I thought this is what the problem was :lol: :LOL: Lets hope :rock:

edit: not the problem :thumbsdown:
 
If I move it, and it doesn't touch anything, it makes no difference, I have the head powered up, MIDI board plugged in, and it doesn't matter if it's touching it or not... should I try and bend it back?
 
Wait a second...Mark... how many red wires are soldered to the MIDI in on your head? From the picture it looks like there are 5.... mine only has 4... are you seeing what I'm seeing? Or do I need to go put my contacts in? :confused:
 
It looks like we have three different Herbert's going on here.

Those ribbon cable ends can be removed, so double check them by pushing down on them gently with your thumb.
The phantom voltage for the midi comes from the main board through the ribbon cable to the back board.

Do you have a Multi Meter ?
 
No multimeter... I can go get one right now if I need to, I was going to pick one up anyway... why would my head have 4 wires and your's 5? the top middle pin on that MIDI input is there by itself... the one to the right of that (moving clockwise) has a single wire soldered to it, then moving further clockwise, the next two metal pieces are both soldered to ONE wire... yours seems to have 2 wires soldered to them individually...
 
Your Herbert is newer.

Take a look at the pins on the midi jacks from the other side. Maybe one is too stretched out to make contact.
 
What do you mean by stretched out? I pushed all the pins forward from the inside thinking that might help and it didn't do anything... is it safe to be touching these things while the amp is on? I really appreciate all your help...
 
Watch what you are doing because your near the power transformer. The mains need to be on, but the amp can stay in stanby
as you only need the low voltage system to give the midi jack 12V+.

Stretched out would be that the contact pins inside the jack are spread too far away from each other and do not make contact with
the inserted cable's pins.

From the Herbert Manual:

Midi in receives “program change” orders from commonly available midi pedals and control systems. The Herbert is able to supply phantom power to your midi pedal via a 7-prong DIN midi cable. This can help unclutter your stage system and rids the artist of these pesky power supplies.
Pin 1 and 6 is ground (-) Pin 3 and 7 is hot (+)
The voltage is 9-12V AC or DC, which is acceptable for 98% of all midi pedals. Maximum power usage of the pedal cannot exceed 800mA (0.8A) Please observe proper polarity to avoid damage to the MIDI pedal.
