Official Mesa IIC++ Reissue?

  • Thread starter Thread starter TheGreatGreen
  • Start date Start date
Well as it turns out… the people complaining on the internet were on to something… Paul Azzi was right all along and people tried to say it was him not knowing what he was doing. We get it… you don’t need to turn all the settings to 10. But there is a flaw. Randal Smith made the first prototype and it was unstable. It’s possible Gibson fired him before he could get it stable and just rubber stamped it…

Earlier in this thread I asked if there was a way to bypass the reverb and just take it out of the circuit by leaving the pedal in and there were a few folks that said the reverb caused noise.

Dann Val made an outstanding video demonstrating what causes the oscillation. I can’t believe this wasn’t figured out sooner considering how simple it is. Maybe some people knew, but they just didn’t want to deal with posting about it…

There are a lot of threads on the mark iic++ by now, but this is the main thread, so I just wanted to update it.

TLDR: Remove 2nd power tube and unplug the reverb! The oscillation is caused by the reverb circuit sharing a tube with main circuit. No mods required, just simply plug it back in if you want to sell your amp

Here is the video:

Just a note to plug back in the power tube after you’ve pulled the reverb preamp tube.

Wondering what was the fix for this in IIC++ RI?

I'm surprised you can read anything on this forum from so high up on that horse

for being excited for some good news about an amp I own and consolidating the information on to the main thread? Or did I miss something?
 
Surprisingly few for sale in used market at the moment. Wondering how many ++s are still on their way to the dealers worldwide?

I'm actually a bit surprised by this. The ones that were listed sold for $6-7k, which is an easy $2-3k in profit. It's tempting to flip at that price point.

Indeed. Maybe, and I hope, the amp is so good nobody wants to sell it. 😁 No new updates of the one I bought around 4 weeks ago from German retailer. The last info was that a shipment from Mesa should arrive somewhere around mid/end of August.

There are a dozen or so waiting for tarriffs to clear up before getting to Canada.
 
Any non-US folks who still haven't received their IIC++ RI?
The counter-tariffs from Canada were dropped Sept 1st, and I got news that amps are starting to move again. I'm hoping it gets here soon, it's probably on pallets being freight shipped to warehouses before being sorted and sent to individual stores so slower than direct shipping would be.

But those are amps that Long & McQuade in Canada had received in July and were just holding in the US until they could import them. They had the amps since release and just couldn't ship them.

If you contact your dealer you they should be able to figure out if they have amps and are just waiting to get them imported, or if they've just got an order in with Mesa Boogie hoping to get an amp (this seems less likely, they should all be allocated to dealers by now). There were some cases where someone tried to place a pre-order and ended up with an order for the HRG reissue they're doing in the fall instead so if they think you're still on a list for an amp they don't have yet it could be that.
 
The fix (synopsis- Take one of the two reverb ground wires and move to a single location. Gets rid of the ground loop)
