I agree that "use your ears" is the best advice
Here is why
Over the years, I've found hybrid amps (amps with preamp tube or tubes) and the tube pedals fall into 3 categories
The tube is a fully functional integral part of the design/tone
The tube is barely contributing to the tone
The tube is a pilot light...often joined by an actual led pilot light to create a tube glow illusion.
But here is the catch, any of the above can sound great.
If Tech21 incorporated a "pilot light tube" into it's VT pedal, wouldn't it still sound like the same pedal so loved by many?
And we'd all probably swear its the tube also.
Just because a pedal or amp is using a useless tube as a marketing gimmick doesn't mean it's still not a great amp or pedal...... just a dishonest one.
