Two entrances, one switch, two volumes, one output, a two-color LED indicator (red or green)
Powered by 9V battery or external jack to standard Boss.
Screen printing is clear, a manual would be superfluous ....
I use it as input to a pedalboard to switch to another guitar while balancing appropriate levels (humbuckers to single microphone for example).
Not compromise the sound or noise parasite as well as on battery power supply, or snap switch.
On paper, a great thing, the boost, setting, wharf! But that was before the plug!
Well, AB is a box eh! nothing really bad
No manual, logic!
Linear knobs, without the breath it would be nice!
Then there is the end of the end !!!!! never seen a device as simple as being able to do much damage!! breath of breath and breath! I tried everything, dedicated power supply, different brands ........... nothing to do!!
I use it in my pedalboard for a guitar (strat Harmonica and microphone (hence the need to balance the entries)
Good in the end I removed everything, I kept only the two knobs and boiboite! after an hour of welding and 3 taken Djack females (those origins do not mount without PCB!! or else I would have had the washers that I did not) I turned into ab passive box (I still kept the two knobs in series!) and there is happiness! " Ok we forget the boost on the other hand I can now balance the sound of two entries!!
At the same time is ca Chero the passive AB Box!
There must be better I think the Boss LS 2 home, but it's more expensive!! Otherwise, the Nano is the best!
In summary: do not buy that hand and if you do it yourself, if not as € 38 throw out the window
