Original version with the plastic grab handle. :thumbsup:
 
How hard would it be to mod it to have the Gain taper of the Rev 2? Any walk throughs online?

Call Bogner with the serial symbols, it may have been done already. If it hasn't, they can probably do it for you or tell you what to have done.

Are you sure about that? Is this statement Amp-god approved? ;)

I consulted with his Holiness, it is Amp GOD approved. :D
 
How different do the Rev 2 and Blues sound? I have owned a rev blue before and like it.

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 :D , 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.
 
From what I've heard (as I have only played the Blue Rev. and TJ), is that the Blue Revision is a little more focused and not quite as wide and 3D as the Rev. 2. When the TJ was being shown prior to release I had heard there was a part sitting on top of the headshell that tipped someone off / made them think Bogner was going back to the Original/Rev. 2 sound.
 
Absence of loop volume and you can see the blue can's through the rear grill + the plastic handle is a dead giveaway to a the 1st version. All the caps were relocated underneath on the pcb for the Rev blue. I bet those will be more sought after at some point, very brutal sounding if my old Rev 2 was anything like it except for the gain taper of course. :lol: :LOL:

When I had both Rev 2 and Blue at the same time and A/B them there were some things I liked about each and some I didn't. At the time I wished all the positive attributes I liked about both versions could be melded into one amp lol.

Is the Twin Jet really that good?
I don't think so. Not stock. The other versions of the Uberschall used EL34s, something I believe to be necessary with this amp for it to feel "together". I was sorely disappointed when I first got the Twin Jet because it sounded and felt - to me - mediocre.

After switching to EL34s, however, my new opinion is that yes it really is that good! I love the voicing and flexibility in setting it up, but the big differences from other versions are 1) the first channel and 2) the added master depth and presence controls. IMO, the depth control is the best thing the Uberschall can have. If you want a huge low end, turn it up (this sounds like the other versions of the Uber); if you want to tighten the amp and get more aggressive, turn it down a little. The amp I now have can be set up many different ways, and still does the classic Uber tone with no problem.

But if you're not willing to think about modding to EL34s or you need a decent clean channel, I couldn't recommend the Twin Jet over another version.

honestly i didnt like my twin jet when i first got it but i had to really sit with it and twist the damn knobs for abour 2 months to get familiar enough with it, it really is a completely diff amp from the other ubers

i managed to get a pretty sweet clean sound out of it and i have the origional version without the clean mod and i use emgs which are really high output pickups .....

i did this vid of my cleans with a dry signal of some boss delay and chorus, it sounds pretty nice and spanky without the effects

I forgot how good your clean tone is. IDK though; I just can't do the same with mine, even if I dial in your settings.

the gain knob is really sensative on this ch

its either kinda clean or jumps to semi dirty cleans try setting the master and channel volume at like 12 oclock and tweaking the gain knob(very carefully, as if you were defusing a bomb) on the first channel until the volume just starts to kick in ..... its wierd cuz when i re eq'd that channel one day i lost my clean sound .... i had a real hard time finding the sweet spot again but after messing with it for a few minutes i got it again .... it was a real pain in the ass and it really pissed me off haha

now i mark the amp with my settings so il never lose the spot ever again......its such a wierd amp

i also use diff preamp tubes from the stock chinese ones i thought they sucked all the fatness out of the amp and made the highs raspy sounding.....i use all tung sols in v1-v5 and a lps in the pahse inverter ....... really beefed it up in the low end and seemed to add alot more definition

i tried all tung solls in the amp but i found the sovtek in the PI really evens the sound out and make the amp feel quicker in response
