i've been doing some testing lately.....
my one frontloaded diezel 4x12 has v30's and the other has diezel eminence custom speakers.
i knew i always preferred the tone in my Eminence speakers more and i use the v30 cab on the opposite side of the stage so i never really hear it up close.
when we loaded into our jam space the other day my singer threw my vh4 ontop of the v30 cab and and the next practice i thought what the heck i'll use this cab today just to see how it sounds.
immediately my bass player and drummer gave me a weird look when i started playing some riffs "dude, why does your guitar sound so thin today? what's up with your amp? the sound is brittle, can you turn up? did you change something?"
i took my ear plugs out and listened.....and they were right, thin, brittle wimpy, and terrible bass response....i checked all my cables and connections to make sure that nothing was amiss and that the only difference was my speakers...
i had no idea v30's sounded that bad.... so i switched cabs and went back to my trusty old deizel eminence customs cab. and WOW . boom huge sound, articulate, warm, cutting and amazing bass.
everyone in the band heard it as well.
it makes me want to sell my v30s and get more of those custom diezel speakers.
i seriously love them.
