i have a valve amp 30watts and i can turn the amp all the way up and
it distorts very little shouldn't they be very distorted if turned all the
way up or even half way ? if so what would be the problem

also who can stand playing that loud in a small room this is just 30 watts
and i thought my ears would fall off help any who have 100 watter's
you have to be deaf in order to get power tube saturation.


thx

Turn up the Pre-Amp knob more.



^^^ ? - you've lost me on this , im trying to saturate the power tube
to the point of distortion and i thought you just turn the volume up
till it did so or is there another way ?

and when i turn the volume up it doesn't distort much at all just gets
really loud clean .

...Are you on the clean channel?

From what I understand, the Delta Blues isn't a single channel amp. Turning it up until it breaks up only really works on single channel amps.

Anyway, that's a really archaic method. Any good amp will have good sounding distortion from the preamp, which combines with the poweramp.

Straight up power amp distortion can actually sound pretty bad.

Crank the volume. Add pre amp volume until distortion.

That's the wrong amp for power tube distortion...

Nah, I can get my Valveking 112 to power tube saturate very nicely..well, sorta nicely at 10.

It's the amp, Peavey is well known for biasing the tubes extremely cold, so you wont get much power tube saturation out of it by cranking it. If you want more power tube saturation, have a bias mod done to it so you can bias it hotter, or get a new amp.

i'll go with the wrong amp crowd. not every amp will give you great power amp distortion just by turning it up. depends on the amps circuit design. some like old marshalls will do this others won't. oh and being single channel has nothing to do with this, it all comes down to the design. many multi-channel amps have the clean channel desinged to stay clean so they don't distort much. so once again it comes down to design.
#13
its a dual channel amp that has preamp distortion ( preamp sat ) but as you all know
the king of tone is power tube distortion that's what i was trying to get .

i didn't know you could bias an amp so much that the power tubes wouldn't distort
i thought you just turn it up and you would get it .

Alternatively you could try EL844's in the power section. They're designed to break up earlier...

The first one is only true if you like power tube distortion. Lots of people don't.

Secondly, you will need to add preamp gain in there to get the breakup you want/need. Those older amps had preamp and power gain coming out of the amp with the same knob.

You're not going to get much breakup if you don't turn the preamp gain up. That's one of the reasons why the master volume was invented, so you could stay cleaner at high volumes.

^^^ i dint know that , the gain don't sound bad it has a classic rock type of tone Ac/Dc type
does surprisingly well .

when you solo it looses its charm it just don't sound like the notes
stand out you have to pick the the notes really strong to make them sound but playing chords/rythem does fine at the same level i guess a compressor or
EQ or more gain would do better on solos .

Right. But we are suggesting the EL844s. Two 4s. It's a variant of the regular EL84. Drop in replacement. They are designed to break up earlier.

are you sure you're not getting breakup? I have a classic 30 which is essentially the same. it gets dirty blues break up at 5 on the volume. push it to 8 or so and it gets pretty marshall-y.

If you order from eurtoubes, I believe you can leave a comment on the order specifying what level of headroom you need. I got the medium clean headroom, so if you're looking for earlier breakup you could ask for low headroom.

I'm using a matched quad of jj el84's btw.

^^^^ i get a slight break at level 9 in the power section on clean channel but its
so loud and not enough distortion to even be noticeable .

if you want an extremely clean tone at a loud vol this is it

im not to worried about it just wondered why it didn't get any
distortion while vol was up .

Im thinking of going digital looking at the Avid 11 rack it cost as much
as a new valve amp with a-lot more options and effects .

those people on Youtube seem to get good sounds from them and you
can hook them right to the computer and record .

i might not like seeing my valve amp gone though

And when it comes time to gig you're not going to have an amp. You can retube your amp for $50. Just do it.

+1. I had old sovtecks and order the hi-gain lead with good cleans retube kit for 80 bucks. I can definitely tell the difference.

If you're worried about gain you can use the second channel with an OD and it should be sufficient.
