Output Jack nuts will not thread on post. Wires broken at soldered connections. After fixing all this I doesn't work at all;.. Junk

Seems well made . But beware, unless you already know how to wire it... Good luck finding instructions.

Doesn't come with a wiring diagram is my only complaint so keep that in mind if you are wiring it yourself

Llegó rápido y todos sus componentes funcionan perfectamente, el preamp es marca Mings y respondió perfecto, ya lo instale y funciona bien, seguiré comprando el mismo artículo.

I put these on a cheap Glarry 5 string with dual HB's and was blown away by how much better it sounded. The original pickups sounded thin and dull to me. The original pickups (still in the guitar) aren't nearly as hot as my other basses. After putting this in I instantly knew I did something right. So much more tone control. Sounds much fatter with great thump.

Por el precio es muy buen producto, falta poner algunos cables blindados, todos los controles hacen bien su trabajo, solo el agudo mete algo de ruido, si lo recomiendo

Installed in a glarry 4 string. Now it sounds just as good as my dean edge 5 string. No problens with the wiring although directions would be nice for a novice. The blend pot board is labeled p1, ground, and p2. Awesome cheap upgrade for a cheap bass. If I didn't already have active pickups in my dean I'd install this in it as well.

Tried to hook this into my bass. It connected and the bass had a signal but none of the EQ knobs hooked up properly.

It works. A fairly easy install that requires basic "soldering" skills. I put this in a Spector Legend 5 string, and it sounds great. Much prefer the tone and EQ range (treble/bass) of this budget preamp over the original. I have the "2-band" version so can't speak to the 3-band version, or longevity of either.
