Hopefully you aren't referring to my statement. I've had more than a few people directly tell me they liked the Vintage tube type because it made their guitar sound older and less saturated, like an old amp.
Yet we all know that it was the most saturated version of the tubes.
If they liked the vintage option, that's totally cool. And I'm definitely not "teasing." But many people described the exact opposite of what it actually did solely based on the word "vintage."
It's a common issue with features on digital units. People let the term and words make their opinions rather than their ears.
No I don't referring on your statement only, otherwise I would name it directly.
Vintage is some kind of a "two meaning word" - in a positive and a negative way. ... I understand your point, but since we just can assume the experience and knowledge of others here, we're unable to tell if someone is experienced or trained ear wise to hear and/or feel a difference.
Saturation is depending on the operation voltages, the bias point and a few other parameters in the circuitry of a tube stage. The difference between various tubes are their characteristic curves, amplification factor, mutual conductance etc. - which made it more or less saturated in various circuit designs. So there are differences hear- or feel-able. As told before, I often use long plates preamp tubes in PCB based circuits with AC-heating as they conduct less hum than short plates. JJ-Tesla still produces a fantastic long plate (JJ-ECC-803) which I use for "Rose Morris"-type Vox AC30 (mid to late 80s) or the tube based Hughes&Kettner Cream Machine, Crunch or Metal Master products.
I most amps, including some very old amps, I using short plates preamp tubes, various brands. Some of the very best tubes around are short plates, we call it in german "Spanngitter-Röhren" (does anybody know the correct spelling in english?), higher mutal conductance, a bit more gain....
and if made with a third mica layer inside, very low microphonic.......perfect for guitar amp applications.
@ OP: Regarding tube "vintage" feel: Try to experiment with parameter triode hardness - I didn't update to latest firmware yet, so I can't tell if you're happy.
Cheers
