Hey guys,
originally had this posted in "burnt fingers" no response. Thought I'd try here. Hope some folks here might be able to help me out as electronics is not my forte ...I use an ART project series preamp for my vox/guits while recording direct to PC.

Will changing the the stock tube to a Ruby tubes

make much of a difference? I want to get a real clean/warm sound even when I'm pushing 10 on my preamp gain knob.
I've heard info that's come down on both sides of the fence: will help a lot and wont' really make a difference.

Anybody have any insight?
And Mud - I'm not going to buy a "brick"!

This is the "Pennycaster Project" I'm rolling my coins to record!
Hope you can help! Thanks
KC
