Bogner Uberschall questions

[Death by Uberschall]

I'm currently GAS'ing badly for either an Uberschall or an Engl SE 670.

My question is, what are the differenses in the Uberschall revisions and what affect do they have on the amp?

I should have saved my replies for when I answered this question so many times in the past

I've had a Rev 2 and Rev Blue, the 2 was darker with the most 3D sound I've ever played, recorded wonderfully and had the better rhythm tone out of the two IMO. The Blue was brighter and less 3D sounding, fast lead lines tracked better and was a little easier to deal with in a band situation because of those attributes. The blue has the external bias test points and the send level control for the loop as well.

I'm sure some of my past responses are searchable on the forum as well

Is the basic sound the same in both/all of them though? Tons of gain, same basic tone, etc.?

How does the Rev 1 compare to Rev 2?

How does the Rev 1 compare to Rev 2?

I'm not sure myself, but I THINK V2 was supposed to have a slower gain taper. I only had the V1 and the gain came on super fast making it more challenging to get lower gain tones. I heard they made the R blue brighter and the send level control. I've never played V2 or blue to confirm this however.

Can't comment on that, never had a Rev 1. Bob Savage might be able to shed some light on that though maybe he'll comment

OK, I talked to a rep at Bogner and this is the jist of what he said.

Rev1 = very high plate voltages and sharp taper on the gain.
Rev2 = very high plate voltages and smoothed taper on the gain.
Rev Blue = lower plate voltages, smoothed taper on the gain, voiced slightly differently, more PCB contruction, loop level control and external bias test points.

I'm assuming the higher plate voltages are probably the reason why they specify JJ/Tesla EL34's in the amp.

As a side note:
I did ask if it were possible to have a XTC head built with the Red channel built the same as the Uberschall high gain channel and he said it's not possible as there many components that make the Uberschall different/special. He did say that they get asked that a lot, so who nows, maybe one day.

Sounds accurate, Because of the external bias points the Rev Blue has a separate PCB strip assembly for the power tubes to accomodate them, where as the earlier revisions had chassis mounted power tube sockets.

I think he also meant the blue version is more PCB where as Rev1 & Rev2 are more hand wired.

The Blue has just one more PCB than the older ones, a separate board that holds the power tube sockets and bias point assembly. I've had both of them opened up, had both at the same time
