OVERALL OPINION

I use it for a year, I'm really happy I did it installed by a luthier, he is very good quality I have no problem with, however, there may be the ger buzz that occur because of mass defaulting. (Electrical outlet). Lger breath.

I have not tried other models, but in any case, it has a positive effect on my bass, it sounds Whereas amliorer possibilitsde and my bass has is clear.

It is CHRE, but not made in china. it's clean, manufactured in England. The report price is good quality, but considering the price, the prfrez nstall a low upper gammme with good microphones, the rendering will be better.

Exprience with, yes, I would do this choice.
