Sent in a shot vintage Jensen C12NA to Weber Speakers, and about 4 weeks later today, I received a newly reconed speaker to original vintage C12N specs. Weber did a fantastic job, and even included some free 'case candy' ( a Beer Koozie and some stickers). Set me back about a C- Note.
I got an old 60's Supro Cabinet of Guitar Center for 246.00 total , loaded with 2x12 original C12N ( A) Jensens. One of the Jensens was shot, so that's the one I had reconed. Then I bought the Supro head to go with it.Both head and cab. are missing the original badges/emblems.;
I think it's kinda an optical conclusion. The 2x12 is narrower than a standard Marshall 4x12, whilst the head is as wide and tall a a Marshall head. I havent got around to taking exact measurements.
