Fender 6G15 Cabinet Build Tips

[roboDNA]

Hello,

I built a fender 6G15 cabinet from 3/4" baltic birch plywood ( tolex ) and it went well, so I now plan to build a 'super, super nice' one from eastern white pine an leave the wood exposed ( no tolex ).  The wood I plan to source from the local sawmill is older with tight rings with no knots ( standard C or standard D grade 'clear' pine ).  I plan to try air dried and kiln dried to see how they each adapt to my shop's climate.  I have the jigs for the 3/8" finger joints for tear-out free cuts.   I see some cabinets from '62 and '63 and the seem to have black paint inside but not sure if it should remain unfinished.  ( maybe just black face was painted black inisde? )

I"m sure I've missed some things to make it super nice and want to avoid finding out too late. 

Any tips on how I can raise the cabinet build to level 11? 

Thank you!
