NAD - ART Pro Channel II

[Roland GR 88]

Sorry Tommy I don't. It was a long time ago. But as the OP inferred, I'd guess any decent tube will be an improvement. I need to do my annual rewire of my space soon so I'll pop the top and report back. There are a few good reviews on the Pro Channel and Pro VLA where they discuss replacing the tubes - I have a newish VLA that has the stock tubes but I only run keys thru it and it sounds fine. To me tubes are tricky and I get a bit cautious when I hear the "mojo in a bottle" line being thrown around, especially when they range from $12-$112. My friend is a guitar player so they likely came from a Fender.

I picked up my ART Pro Channel II yesterday!

I went down into the BASS MENT! lol to dial in a great tone.
Took about 1.5hrs. Sounds great! I'm a compressor user and found this to be functional, yet transparent.

If you look at the Pic, you will notice on the left is the HighPass.
I keep it around 40hz. Any higher and the bass starts to disappear off the higher strings

I found cranking up the preamp helps fatten the tone and removes some unwanted frequencies.
