All,
Feel free to play around with vibration / isolation products. I haven't found any that make a "significant" improvement, but
trying different feet, tube dampers, etc. will offer some change to the sound. It will be up to you to decide if it is better or
just "slightly different" sounding.
The dampers work in very tight spaces, such as the Isabella. They do fit perfectly, though. Vinnie will verify that if you ask him, because he installed them!
Yes, they do.... but I'm not sure if they will for the upcoming Isabella Renaissance Edition (on the 6H30 tubes). As I will post in pictures soon enough, the tubes are mounted differently (horizontally and near the top, instead of vertically).... so we'll have to see...
Best regards,
Vinnie
