I know a lot of people ponder the differences between T-75's and V30's, since they tend to be the most common speakers, so here's a clip for anybody after a T-75 sound.
I picked up this cab the other day from Mr Cassidy, and have managed to tease out a mediocre clip, but really need more play time to find the sweet spot.
Amp settings were:
No boost, guitar straight in.
I used my LTD M-307 (EMG 81-7).
I know people complain that T-75's won't fit a mix as readily as V30's, and I tend to agree, but that doesn't mean it should be overlooked. It's just a different flavour.
One tip - don't try to dial in your amp the way you would with a V30 rig, it will only end in disappointment.
My observations are thus: It's darker, fizzier, more scooped, and woofier. So compensate with more mids, less bass, less highs, and preferably tighter playing
As for post processing I found I had to take a scoop out of the 250hz region with a narrow Q, as it was very boxy/boomy here. That was probably more to do with the room it's currently in than the nature of the speakers though. HP at 80hz, LP at about 9k, but with a hi shelf of 2.5db from about 6k>.
EDIT: Mic was a single 57 on the cap
Everything you touch turns to gold.
