I agree from the vids that the 25 seems to have more gain, I believe the V 90w has the same amount but you just have to max gain, treble and mid.
My settings are as follows and it is brutally heavy:
- Gain: Max
- Treble: 5oclock
- Mid: Max
- Bass: 11oclock
- Presence: Low and tailored to suit your playing volume and speakers
45w / Tube rectification / Variac. GEQ and Full power optional
It has authority like no other mode or mesa I've heard and probably one of the main reasons why I am keeping the V.
Sometimes I think because of how the manuals are written up with relatively conservative suggested settings we're generally reluctant to push some of these settings. How I feel anyway.
