These recordings were made to showcase the differences tonal characteristics of Celestion's range of guitar speakers. To make this comparison as useful as possible, we've recorded three different guitar sounds or styles, "Clean", "Crunch" (two different samples) and "Distortion."
For each style, exactly the same set-up has been used: same environment, same guitar, same riffs, same amplifiers (valve pre-amp and valve power amp), and amp settings, same cab, all with the same EQ. In all cases the mic location was identical, an SM57 located on-axis, but slightly off-centre. Any differences you hear are genuine differences in speaker tone.
