In the Fractal, lowering the B+ time, and lowering Supply sag can tighten up an amp. Turning off the preamp sag, and changing heater supply from AC to DC can also help.

I 100% meant mod his actual amp haha.In the Fractal, lowering the B+ time, and lowering Supply sag can tighten up an amp. Turning off the preamp sag, and changing heater supply from AC to DC can also help.
Cant really change this in an amp though unless you add more capacitors to the power supply line.
Play one note, hear two.Ghost notes? Struggling to conceptualise that sounding
Bass amps use lower ohms partially because it gets more power without changing specs, not sure its overcoming an impedance path. @MaxOfMetal or @technomancer may be able to put it straight.Right on with using the clean booster for delivering a more massive signal to the amp front, regardless of pedal chain.
You may find it a little more "cleaner" and "flatter" sounding if you also use low capacitancy cables to avoid the muddy bass from high capacitance.
Another thing would be the low impedance cabinets. There is a very good reason that Ampeg and other bass cabinets uses 2 Ohms circuitry as this helps lower frequencies to "overcome" the impedance path more consistently with the higher frequencies.
However, there is an important point I am missing from this topic: if this Bogner has the option to change the rectification mode as well as the Dual Rectifier does, you may find that the Silicon Diode option gives you a response way quicker than the tube.
Honestly that is pretty damn interesting, I'm in no position to talk to Bogner about a mod but this is something I will definitely keep in mind.

Just a general update and some replies. I did just get a st300 turbo tuner and I believe that has a buffer, need to make sure it's active or whatever.
Also I do have a couple of boost pedals on the way and will probably buy some greenbacks to swap the 75s in my Uberkab just due to the curiosity.
With that said I think some of my issue was user error. I was talking about this on another forum and someone touched a little more on the Metamorph control. It had dawned on me while I definitely swept it a bit, I never tried it completely off.
That kind of opened a whole new world on this amp between the way the morph interacts with the tight/fat switch and Honestly that is giving me what I was looking for.
The low end response is better/seems faster and tighter while also giving me a little more sag at the same time. I know it sounds contradicting but that's the best way I can explain it.
Now if I hit those open low/quick djenty type notes it gives me the perfect sag just like the Rev 2 Uber did BUT at the same time I have better control of the low end and response time.
Essentially user error. This amp is insane guys. While the core tone will always be there you can manipulate it to no end. Really need to spend some time with this one.
Not to mention boosts and eq coming.
I think Engl is the brand for super tight clean death metal but I'm sure theres more.Was thinking about trying one of these, but considering my biggest thing I dislike about amps is voltage sag, I think you just cured me of wanting to try this one out. Was my biggest complaint about the Rivera and the Recto. Saggy, squishy attack. Some people call it bounce. I want it to track like its pristine clean.
everyone that's saying it's all about the power supply / B+, particularly the B+ filter caps - is 100% bang on.
anything else is bandaid bullshit.
yes you could decrease the required bass response in front of the amp with pedals and other shit to help the amp "catch up", but that's not solving the actual (perceived) 'problem'.
I know nothing about this amp, but given its a high gain bogner, i'd very surprised if it didn't already have a super robust power supply / filter cap network.
this is from the og uberschall:
View attachment 142296
with x2 470uF in series (to maximise voltage rating) and x2 of those in parallel (to double the capacitance) - makes up for a total 470uF.
that's fucken huge.
if this amp is anything like the og uberschall, well fuck, i don't think adding more filter capacitance is gonna change a lot, or help.
e.g.
for comparison, this is the SLO-100 B+ filter cap network:
View attachment 142297
x2 200uF in series, doubled in parallel --> that's 200uF total (B+1)
5150ii:
(5150 also has the same power supply):
View attachment 142298
x2 330uF in series, that's it. makes for a total 165uF filter capacitance (B+1)
ENGL powerball:
View attachment 142299
just x1 (500V) 220uF cap - 220uF total (B+1)
so if this amp is anything like the og uberschall, im gonna guess it's likely to have a more robust filter cap network than most other high gain amps out there.
looks like Diezel schematics are heavily guarded. I can't find any that include the power supply section (only found a preamp for a VH4).I'd be interested in seeing Diezel specs on this stuff. The Herbert was really 'fast'. But massive bottom and was darker/smoother in tone.
How Does the attack feel when the gate is unplugged and removed completely?With the settings above it is the best sound I have been able to get.
Any more presence is too fizzy. Any less depth I cant feel it. Yes if I was with a full band and a bassist I could certainly change things.
The pedals are a tc Sentry in 4CM which doesn't change the feel, response or tone very much at all, very slight Iike any other gate and an SD1 which probably isn't even on, was just testing.

for a Herbert, all i could find was this low res gutshot:
can see there are x2 fat black filter caps? (no values visible).
and those big red WIMA film caps everywhere (doesn't really get much better than this)
if you can get a hig res gutshot, that could tell us more...
