Ok, I admit it. I bought the Marshall 1960a because - 1) it was on Craigslist for a good price, 2) it was in brand new condition, 3) and it just looks cool in my pictures. However, I also have to admit that it's really too much speaker and it loads up my iso-booth with too much bottom end.
This cabinet will never come out for gigs so there is no reason why I should keep it because, if a guitarist wants a 4x12 sound, I bet he already has one and it's probably better than mine or I just don't care.
So I'm thinking 1x12s or 1 x 10s with or with out backs. Even my beloved 2x12 Lopo with Celestion Blues could be modified. I'm thinking a 12" Greenback, maybe a Jensen and some other speakers in separate cabinets to experiment with.
