Other than the Allston company near Boston using a G12T75 in their Dumbalina combo, G12T75 are not favored speakers with Dumble players. They are the perfect speakers to get lost in the stage mix: boomy bass, scooped mids and icepick treble!

I just finished my ots build and am shopping speakers.  I picked up a 212 Marshall with g12t-75s for 100 bucks with the intent of cutting the back, selling the 75s and upgrading to
g12-65 or evm or even vintage 30/greenback mix.  anyway, i played my first job with the ots yesterday.... Although by band liked my sound, and it sounded good in rehearsal, I HATED it on stage...I got usable tones but got lost in the mix except the ice pick tone.  I almost went to get my fender deville and tube screamer out of my trunk....  I'm pretty sure I won't ever play a Marshall cab again for a show.  It was just ok not great.
