Yea I had a VHT cab for awhile 2x12
When I got the 1960A cab for my JCM, I was very unhappy with the muddy Celestion G12T-75W speakers (imo they are pure shit). I bought 2 Celestion Vintage 30's to mix in and bam!!! Instant Slash Paradise City nailing on the G Chord. lol. or uhhh KOHD etc

The cab was either too in your face loud harmonics with the mud and overly sparkle of the v-30's..... that I sold that cab. and got a Marshall Greenback cab.... that didn't color my sound, didn't mud my sound... didn't lift my sound in an unnatural way. It did what it was supposed to.
I miss that cab

& the JSX. Now I only play a peavy 20 thru a Orange 1x12 (its sweet). Ripped out the V-30 in the 1x12 and put in a speaker that was made in the states... a replica of the original Greenback.
((edit)) I forgot that I own a Vox Valvetronix... I never use it.
