Was the Bogner Twin Jet a let down??

[fickle]

Yes, Indeed ! Really dig my Rev. Blue and Mills Acoustics afterburner. Tonight will be my 2nd gig with that rig. Its awesome

I mean I guess it's why music today sucks so much...

Really??? I mean, if I had to compare to classical music I would have to agree with you, but I don't think that's what you mean. As far as comparing today's band's to 70-80s music, IMO there are a lot of better bands today, of course you won't find them aired on the radio, but that's another topic of discussion.

I do agree that revisions don't make a difference.

It's a total joke, where's the mailman?

I wouldn't have bought a blue revision...it was too dark and compressed for me. The Twin Jet fixes those problems I had and has a great 1st channel as well. I am, however, thinking of swapping out the 88's for 34's, as the 88's have this glassy tone I don't like...I wonder if those who sold their TJ's would've kept their's if they made the tube swap?

I wouldn't say the Blue Revs tone is a "problem" but I do understand your preference for a different sound. Dark and compressed is definately not for everyone and I would say in that case the Twin Jet would be a better choice. I thought about the tube swap, wonder if it would have made a difference. I just figured the KT88s were the Twin Jet's thing so if you don't like it with them, time to move one. Has anyone put 34s n there?

Did not dig the Twin Jet, LOVE my shiva aniiversary to me that amp is really aggressive and bad assed KT88 tone

I wouldn't say the Blue Rev's tone is a 'problem' either, just preference - I prefer more open vs. compressed...neither is flat out better. TheMagicEight has put 34's in his Twin Jet and has said that he can't recommend the change enough, if you find the 88's lack a certain something in the midrange.

Do you know which components had to be changed and what values were needed?

 

[Mailman1971]

Was there ever a rev 1 or something before the rev 2 Uber?

The ORIGINAL

And by God it hurts...

Like the hammer of GOD!!!

Are you sure its not a Rev Blue Version?

That would be the Revision Black & Blue

Are they Snortable? Thats all I care about.

All this talk of revisions and all, but does it really matter in the long run, I mean I guess it's why music today sucks so much...

Revision this, revision that... the main thing is I've put all of them up my nose before amps were even amps at this point....

"I blown up more amps and snorted more amps than half those ass clowns at "Riff Talk"....Hell I am even a member there...."

So Says the Amp God........

Sure do man. Here's what TheMagicEight sent me (hope he doesn't mind me repeating the instructions)..he told me it made the amp richer harmonically and the feel was more to his liking (like old school Marshall). Here's the steps you need to take:

1. Remove power tubes and all cables and take your amp out of the chassis.
2. Locate R401 (near the bias pot) and remove both resistors (there is one piggybacked on top of another)
3. Replace them with a 1/2 watt resistor around 47K Ohms. I suggest getting them from Mouser, but you could go to a RadioShack and that would work.

http://www.mouser.com/ProductDetail/KOA ... bLhdAaw%3d

4. Looking from the top down on the outside of the chassis, turn your bias pot counterclockwise until you can't turn it any more.
5. Insert your Bias Rite and EL34 power tubes.
6. Put your amp on standby.
7. Flip it to the on position with the Bias Rite measuring current, not voltage. If it goes higher than 38, immediately flip the amp back to standby. For me, it went to about 30 - 32, which is about where you want to set it.
8. Assuming you can, bias your amp to where you want it, then put it back in the chassis.

If you find the range is too hot for your EL34s, you might need to use a lower resistor value. Repeat steps 3 - 7 with something around 40K Ohms.

A bit late to join in, but maybe I can still contribute something that hasn't already been said....

When I first got my Twin Jet, I had mixed feelings. I bought it without really hearing or playing one and went off of glowing reviews (as if I hadn't learned my lesson after doing the same with a Basson cab). Anyway, the Uber tone I was used to was Rev. 2 / Blue, and the Twin Jet sounded pretty good, but it lacked something I couldn't put my finger on. As time went on, I was getting more and more frustrated because no matter what I did, the amp wouldn't cooperate. Tried different guitars, different cabs, different preamp tubes, cables, bias settings, rooms, and of course, amp settings. Nothing worked. I got to the point where I actually thought something was wrong with the amp, then it all "clicked" for me and I realized the thing lacking was a rich midrange and EL34 feel.

Since modding it to EL34s, I firmly believe the Twin Jet is a step up from Rev. Blue for my needs. Before I thought the first channel was a bit off, with harsh upper frequencies that never sat right with me. EL34s fixed that. The second channel is also excellent, and with the master presence and depth controls, the complaints of Rev. Blue's lacking power are fixed by turning depth down a little. Now, I've got a 2 channel high gain monster that I'll put up against anything. Maybe I'm just an EL34 guy, but more likely is that I think this amp flat out sounds better with EL34s. Then again, I haven't tried it through a new Uberkab, but I doubt it would make too much of a difference.

Anyway, my bottom line thoughts on the Twin Jet is that stock with KT88s, it was - for me - definitely a letdown. If you're able and willing to mod it to EL34s, it's a fantastic amp with arguably more ways to set up than other Uber versions. For a taste of what I mean, check out some of the clips on my soundclick - see sig for the link. I haven't changed my settings too much since then, and though I wasn't trying to do much with the playing, I believe the tone gives a fairly accurate representation of what my TJ with EL34s can do!

 

[se7en]

TME: Thanks again for those instructions. I'll probably do swap within a month or so. The KT88's are nice and open and they make for a cleaner sound - I can see why metalheads would want to use these in this head, but I think I'm just an EL34 guy, through and through. I'd imagine the change would add somewhat of a richer midrange, with not quite the low end of the 88's...the extra saturation is also what I'm looking to gain. I think, the glassiness and somewhat dryer sound of the 88's just aren't my thing...I do like the definition of the 88's, though...hopefully the switch to 34's won't hinder that too much.

 

[Motorpud]

First Uberschall I played heard and owned had 6550's. Beast of an amp. Second had EL34s REV Blue. 3rd and Best Uber to date has KT88s. I love this amp and Reinhold made it a KT88 version for a reason. It is built around those tubes. I have no idea why someone would not just sell the TJ and buy a Rev. Blue as they are plentiful. Personal preference for sure but this version is way better to me.

What're the differences between 6550s and KT88s? I was under the impression the were pretty much the same. Well, not the same but you know what I mean, very similar, not much discernable difference.

KT88s are an important change, but it's called Twin Jet for a reason. Channel 1, presence and depth are all new features that aren't as easy to obtain on a Rev. Blue as EL34s on the Twin Jet. It's very possible that I'm not hearing the KT88s the same way you do, but EL34s really made this amp perfect for me. Wouldn't want any other Uber.

I just find Kt88's to be not as rich in the midrange as I like. The Rev. Blue was just a bit of flubby and was noticeably more compressed...also did not have the cut of the TJ. I can see why the metal guys are liking KT88's and why RB decided to go with them...I just like the feel and tone of 34's better...

 

[TheMagicEight]

And I respect yours and anyones opinion as they are all valid. I sat next to Reinhold when he was in final voicing of the first run (6550s) all designated for Europe. He had a Dual Rec which sounded amazing which belonged to Lynch or Stevens or some popular guitarist as I recall.Serial # 45 I believe. The Uber after RB was done playing around crushed it.

He has always risen to the challenge and the Twin Jet to my ears is a better amp and that doesn't mean shit. I am happy for guys that find their sound and mine lives in the TJ with KT88s!!! I did upgrade the tubes but it kills and I could not be happier. I am glad you dig it with 34s. Great amp either way.

Well said! IMO, if a player is happy with his tone, everything about the music seems to get better.

 

[Big Rich]

i really have a love/hate thing goin with my TJ

on the twin jet i like the first channel alot better than the 2nd, its less noisy and a little more dynamic.....but ch 2 seems better if your into scooping your mids, thats where the real broots are

its an insanely in your face metal amp (IMO its THE metal amp to own) but i think it falls very short of being versatile. and to get different sounds you deff need more amps.

the cleans and effects loop are god fuckin awful. honestly for an amp that fukin expensive it should dish out all the decent tones you need

 

[Shiny_Surface]

I think theres a much easier explanation for why Reinhold has used different power tube types in the various Uber revisions throughout the years...tube availability and prevailing market conditions at the time of release - a simple business decision.

Anything more than that and you're into cool aid drinking territory imo.

I'm sure any and all of the various revisions would sound fine with either power tube type depending on the individual players preferences.

Hey Se7en, if you put 34's in your TJ can I try it again?

You got it man...I'll let you know. I agree with with what you said about the power sections...well said...in the end it's really just down to preferences...
