I got mine at the same store after Jerry told me about it.
You have to LIKE YOUR CLEAN TONE.
If you are pushing lows already....nope.
But here's a great explanation.
I had gotten mine for $30 and let a client have it that used it on every song on a record
There's a big truth in that statement. I think a lot of the Nashville guys use big iron amps that are able to handle the low end response of the Nobels. A Princeton is a whole different thing, the low end on that amp is already flabby and adding more will just turn it into mush.
I had the Nobels ODR-1 reissue and now have the Nordland. It does everything the ODR-1 does and let you cut bass, cut/boost mids, decrease the compression. A fantastic pedal. But as with the King of Tone, it won't suddenly turn the average tone into something magically. Make sure you are happy with your basic tone and use it as another gain stage.
