I bought my Boss Micro BR last month and so far haven’t used it much until today. I needed to get my head around some basslines for a gig and I hadn’t played them in years, so I used the Micro BR as a little practice machine, and it worked really well. I realise that this isn’t a true test of its capabilities, but a good first step. I have to say that so far I like the unit, although the centre cancel feature on it produced some very strange results.
Anyway, I thought I’d also point you at a good review from Sound on Sound.
