Hi, can someone help on volume characteristics of a tube amp

[L60N]

Hi all, Ive just signed up hoping to get some advice/feedback.

The title says it all really, I have a newly purchased 2 channel Rebel 30 amplifier which I absolutely love! It sounds full when the volume is above say 2 onwards, however when lower, in a practice scenario, its a little "iffy".

When going from 0-1, the sound doesnt come in gradually, it goes from 0 to "sound" in a marked step rather than gradual, sounding a touch scratchy too. Is this a pot issue?

Lastly, from say 1 - 2, again the volume doesnt increase gradually. At 1 the sound is very thin and trebly; turning the volume up further there is a noticable step up again in volume to a fuller vibrant tone that you would expect, then smooth onwards.

Taking the above in account, is there a problem or are these things I describe characteristic of a tube driven amplifier?

2 onwards is heaven btw.

Thanks in advance for any advice offered.

I don't think that is anything wrong, I think it is just the design. I have noticed that on many amps, particularly a Fender I was playing recently.

You might be able to upgrade the parts to fix it. I don't know.

My Rebel 30 does the same thing.. I also have a few other tube amps.. Fender, Mesa etc.. They are all very touchy between 10 and 1 on the volume knob...

If practicing i will sometimes turn the amp on 2 and adjust the volume on the guitar..

That definately puts my mind at rest. Cheers regulator1.

Sorry I meant say between 0 and 1... Not 10 and 0

Kinda reminds me of the old Twin Re-verbs....
Zero was silence and one was deafening.
