Avoid Markbass
I would avoid buying from this company. After my amp died following only 3 years light use at home I opened it up to try and repair it. The build standard was not very good at all. I contacted Markbass in Italy for advice on repair. After a promising conversation and first contact with a chap called Fabio, they went quiet and did not return calls or emails. Things go wrong of course but this company have terrible customer service.
