Re: Mesa OEM V30 vs generic V30
Are both speakers in the same cab? The first sounds warmer (chunkier mids) the second more aggressive
The Mesa V30 is in the black cab 1x12 and the Celestion V30 is in the tan combo's cab. Both are basically the same cab (the black is an extension cab), only the combo is slightly taller to make room for the amp chassis. Both cabs are open back with their back panels off to try to eliminate as many differences as possible.
The Mesa has a stiffer response and a fuller midrange, including a lot more low midrange.
The Celestion has a softer response and less mids, which gives more emphasis to the upper mids.
The recording was done at a fairly moderate volume (loud, but not too loud) to avoid overdriving the camera's mic. Lower volumes favour the Celestion where the softer response and upper midrange "sparkle" sound a little more musical than the Mesa's stiff, kind a dull sound. However, as the volume goes up the Mesa becomes a lot clearer, stays tighter, and starts to produce and aggressive midrange crunch that the Celestion totally lacks.
The video kind of captured the middle volume area where neither speaker was really disadvantaged, but it wasn't loud enough for the Mesa V30 to really shine.
