This may give a boost to local music stores.
I expect there's enough UK based online music retailing that it should remain competitive on its own without needing EU sellers in the mix. Then the only difference in pricing would be any difference in UK and EU VAT rates.
Where it could get sticky is the fragmentation of international warranty service for US brands. Still the UK is a pretty big market by itself.
Bass is largely underappreciated, until it stops.
The flipside is playing nothing on an intro, or sparsely, creates a 'dogs off leash' level of excitement when you kick into gear.
Bingo. I can't get my head around playing percussion parts and bass at the same time. All those snappy poppy extras on undefined beats would sound like total garbage if they were fingered notes, but quite choice additions to the kit.
One day I may find occasion to throw in a little slap/pop. I will be looking for the drummer to snap his neck if I do, like the day he didn't notice I had swapped in the slab for the EUB and dialed in a little bit of grind.
