The Definitive “Back in Black” featuring an original Schaffer-Vega Diversity System (UPDATED!)

>>Isn’t it always the same story? Don’t we end up finding what we wanted just at our latest attempt? Just like when you have several keys in your hand and only the last one is the right one! Damn! <<

YOU'VE NAILED IT FIL! It's a mystery.
(Though it is not always like this.- Sometimes the first key of the many has been the right one. That's probably intuition). I had the same experiences a several times. I was ready to give up on my 1976 Gibson SG Standart because studio recordings ALWAYS sounded so dumb and average, just boring, no SG or ACDC sound at all, although she had stock original Patent Number PU's (The problem was epoxy). Since years I didn`t enyoy playing my SG anymore. I startet to search for the reasons and studied guitar and amp tuning – and also the sound and equipement of your SoloDallas account on youtube. After two years of making and rebuilding several amp mods, buying a Plexi 1987x, trying many different Gibson humbuckers ( T-Top, sevaral 70'ies Humbuckers, Angus Young Signature, Burstbucker 2, Tim Shaw, 57 Classic and others, some sounded quite good but not like a classic SG or like ACDC), after trying nearly all Celestion Speakers of different decades I was at the point to give up my SG Standart and to put it aside, but I wouldn't sell it for some reasons. Seemed to be obviously a bad production day or a bad wood. A few months later after installing alu tailpiece and a locking bridge/tailpiece system I took time to install – my very last try – the humbucker into my guitar thats been lying for about 10 months in my cupboard – a burstbucker pro lead, bought via ebay from an US Seller for a very good price.
Than, playing it with a Marshall 2204 and 4 x G12T-75 Celestion non slanted – Guess what. A REVELATION!
Original PAF Sound of the 60'ies or 50'ies, this special hollow 3 dimensional sound, and punchy with such balls, nailed almost ACDC, the original and perfect SG Sound , awesome, could not stop playing anymore, played for hours, could absolute not lay my guitar away! In one second my standart was overtaking my other beloved and good sounding Gibsons, greatest change in sound ever.
Finally, unexpected at the end of my dreams and happy – a happy end after walking a long long and thorny road.
But do all these kind of storys and experiences not tell us, we shall always follow what our heart long for and never give in?

Celestion G12-65: Thats weird. I tested them too, but they sounded so scratchy and somekind of too vintage, no punch (maybe it was because of the a slanted cabinet), too less definition. But it's always the combination, I could not test it with a 1959.

SVDS Replica: After all the comments I've read about the SVDS Replica I am starting to be interested in that thing. That will be probably an optionn for me, later on.

Thank You Fil for all these informations and for your engagement in finding the perfect SG/Marshall/Guitar sound and sharing this with us all!
