Welcome to the forum Death Mantas, I missed your thread.
I have built an IB-6S and I love it. I upgraded to an active system and it sounds great.
Have a read of some of the build diaries to get some ideas.
what are your plans to stain the spalted cap ?
Start a build diary and ask any questions there.
Would love to see pics of the spalted cap you scored. Most of them are stunning
