15W bass amplifier, compatible with passive/active inputs. - Brand: Hartke - Model: B150 - Output: 15W - Input Terminals: Passive/Active - Volume Control: Yes - Effects Loop: Yes Thank you for viewing. This is a Hartke bass amplifier. It was mainly used indoors, and although it was purchased used, it has only been used a few times. The condition is, I think, good. Currently, there is no scratchiness in the volume or other knobs. It has two external inputs, an effects loop terminal, a line out, etc., and is perfect for practicing at home. It also has an 8Ω speaker out, so it might be good to expand it. Please understand that this is a used item before purchasing.
