Well, i built it and for anyone interested i put i pic up in the photo's section.http://groups.yahoo.com/group/cgs_synth/photos/album/1538675616/pic/1794994871/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc
Thanks so much Ken 1) for doing these boards and 2) for your suggestion of doing 2 separate controls for each band,you can create some really cool imaging in the stereo field.
