Uberschall help

[prsplayer86]

So i'm thinking I'm going to go the Uberschall route, but I'm lacking a knowledge base for Bogner in general.

It seems that generic rev blues are fairly easy to come by ,but the twin jet is a tad more rare on the used market. Does anyone have experience with both and prefer one over the other?

 

[WizardSouth-JP]

both are great for what they were made for - crushing high gain rock/metal tones. The regular Rev Blue Uber has a little more give to it and is not as stiff as the Twin Jet. The TJ isn't stiff but is a little less forgiving than the normal Uber.

Clean channel on the Rev blue is clean while the TJ doesn't really have a clean - two fire-breathing channels.

This is the basic rundown of the Uberschalls:

Original - Fast gain taper on Gain Channel (some have said almost like an Off/On kind of jump in gain), high plate voltage, good power section compression/sag when pushed, Clean Channel volume slightly lower than Gain Channel by comparison, plastic carry handle (although some Original Uberschalls got the leather handle just prior to transitioning into the Rev2), EL34

Rev2 - Reduced gain taper on Gain Channel (same gain, just more controllable), high plate voltage, good power section compression/sag when pushed, Clean Channel volume slightly lower than Gain Channel by comparison, leather carry handle, EL34

Revision Blue - Same basic gain structure, lower plate voltage, less power section compression/sag when pushed, Clean Channel volume matched closer to Gain Channel, re-design of circuits, addition of Loop volume control, bias test points, power jewel changed to smaller LED type, dedicated design ability to allow power section slaving from an outside source (but this can be accomplished on Original/Rev2 versions), EL34

Twin Jet 1.0 - Gain Channel re-design in a direction towards the Original/Rev2 designs, plate voltage unknown at this time so I can't say, less power section compression (due to the design switch to KT88 power tubes), Clean channel re-do in the direction of a high gain modded Marshall tone with very little ability to get a truly clean sound, addition of power section Presence and Depth controls, KT88

Twin Jet 1.1 - The same as 1.0 but with a modded gain taper on the clean channel, same level of gain available as 1.0 with the ability to go lower gain and clean up better

Now keep in mind, I made up TJ 1.0/1.1 for the purpose of comparison , I don't think Bogner looks at them that way. Bogner does offer to perform the Clean Channel mod for anybody who owns what I call 1.0 at no charge.

These are the main differences I know about. I don't know specific component values between the different versions from a design stand point, but I can say my descriptions above, for the most part, are right on the money by way of research, comparisons and the general consensus from those who have had time with them. The volume difference between the Clean Channel and Gain Channel on the Original and Rev2 seem to be exaggerated. Yes there is a difference, but nothing that can't be fixed by just turning the Clean Channel Volume control up a little more than the Gain Channel volume control. Another words, adjust the amp with you ears, not your eyes.

Are you sure you don't have the plate voltage reversed Uber? Lower PV will give more compression and sag whereas higher PV will always give higher headroom(less compression/sag

Are you questioning the Amp God of all things Uberschall!!!
The last mortal that questioned my knowledge felt the wrath. See Amp GOD Chronicles in my sig.

I'm sure. There are many other factors that effect compression and sag such as filtering, transformers, gain structure, bias, etc.

You are forgiven.

Rev. 2 and TJ are both brutal amps. I liked the Rev. 2 better but never tried a blue. Rev. 2 seems the most rare to me though.

 

[prsplayer86]

I've played a custom one off for Neil Schon, rev 2 I believe. Blew me away. It was seriously the best thing my ears have ever heard. It however was a tad out of my price bracket at the time and is probably sitting on a shelf in someones man cave for the rest of eternity.

From what I'm hearing though.. .I'm probably going to be happier with a Rev Blue. Really dig the tone of the twin jet clips I've heard.. But I occasionally need a clean channel..
Reza- Will the twin jet clean up at all with the volume knob rolled back ?

 

[leib10]

I wasn't the biggest fan of the Rev Blue- too much emphasis on the upper mids gave it a more Marshall-esque tone than the Rev 2 or Twin Jet, which are darker. I also wasn't a fan of the bottom end.

The Rev 2 has probably my favorite distorted tone of all time, but the Twin Jet is easier to play, cuts through the mix better, and is more versatile. You can get really good cleans if you pick softly and play with the knobs on Channel One a bit. That being said, the KT88s are more expensive to run in them, for some reason it's heavier than the Rev 2, and the loop isn't all that great (at least not on mine; it may need to be looked at).

If I could only own one, I would say go for the Twin Jet. If you're looking for that one gnarly distorted tone, see if you can find a Rev 2.

I've had a Rev 2, Blue, and 2 Twin Jets.

The Twin Jet is the only one that can keep up/feel good with faster palm muting without a boost, just imo.

The Rev 2 had the most 3D dark and brutal voicing, I had to push it a little with an overdrive to feel better under the palm mutes (for my needs).

The Rev Blue is brighter and the clean channel was a little easier to balance volume wise. The gain channel wasn't as 3D but the extra brightness helped in a band mix (for me). I used a boost with the Rev Blue as well for better feel under the palm mutes.

The bass response is different on all 3 revisions, imo.

 

[ibenhad]

As the very happy owner of a Rev. Blue I don't think most people buy an Uberschall for it's clean channel although the clean on the Rev Blue isn't bad it there is a serious volume difference between the 2 channels.

Man, this thread is hurting me.

I want a Bogner.

Dude thanks ! Also I see your in Lubbock ; I just drove through there on my way to Colorado. You play much out there in Lubbock ?

 

[jc986]

I'm very happy with my Rev Blue. The clean channel actually sounds really good and you can balance the volume between channels as long as you keep the master on the lead channel at 12 o'clock or under.

Also per Charlie at Bogner, you can also run KT88's in a Rev Blue if you get a place to source you a very cool grade of KT88's or you can add a resister into the circuit to increase the bias range. This would get you into similar tonal territory as the Twin Jet's lead channel (obviously without the additional tone shaping of the depth and presence controls on the Twin Jet).

No sweat. I don't get to play too much, law school interferes with that. But I definitely cut loose when I can!

I always enjoyed playing Jake's, hoping to get back into the routine of playing it on the regular again. thanks again for the input on the Rev.

No problem. Hit me up if you are ever in town and you can try my other Ubers!
