Plus, with 48 volt phantom power, you don't need batteries or any external supply. Just plug in and you're good to go! Features Active direct box for acoustic and passive bass Ultra compact to fit in your guitar case Plug & play easy to use feature set 48V phantom powered, no batteries needed!

Ground lift is a bit hard to get to, but it's not something you're likely to need to change too often if it's living in a guitar case. Fantastic DI.

Works as it should..very good product.
boosting hi impedance output signal from electric guitar effects pedal to lo impedance board. it works.
this tight here cleared everything up for me.
Stage bug, good performance.
Already used for a gig starring Glen Matlock of the Sex Pistols! He was happy.
Good value for this quality.
I bought this box for instruments at open mic nights. It’s really well built and everything that has gone into it has sounded better than going straight into a desk. The pad and phase reversal switches are useful additions. It’s tiny and fits easily into a guitar case. It will also last. I know you can get active DI boxes a lot cheaper than this but it’s worth spending the extra.
