Yes, it's sorta subtle, but worth it.Are you hearing or feeling a big difference , i am away from the Axe at the moment
And was curious to what tonal changes people are experiencing
Are they subtle or pretty noticeable
When I selected the 4x12 Bassuy impedance curve along with the Bassguy amp and its normal cabinet as a test earlier, it felt more 3 dimensional on my ears, if that makes any sense at all. It also seems to affect the eq in a subtle way. Some curves felt open, whilst others felt more 'pinched' and in focus in the mid-range.
The only way is to try it for yourself later and see what you think as tone's all subjective.
