Hartke B300 is a miniature bass guitar combo from the "B" series designed for home practice.

Power and speakers:
Maximum power is 30W at 8 Ohm load (internal speaker). The combo is equipped with one 10 "speaker with a paper membrane.

Controls and functions:
The combo has two inputs separately for active and passive instruments.
The VOLUME total volume potentiometer follows. Because the input sensitivity control is not used here, the manufacturer recommends sending the strongest possible signal from the instrument.
Equalization is in the form of bass, midrange and treble potentiometers, which can affect the frequencies of 100 Hz, 830 Hz and 5 kHz by + -15dB.

Connection options:
Very useful for recording and live playing is the jack line output located on the front panel, which is connected here only after corrections. For exercise, there is also a headphone jack located on the front panel. When connected, the integrated speaker is disconnected.
On the back we find the jack output to which the internal speaker is connected.
We can even find a series-connected effects loop with JACK connectors Preamp Out and Amp In.
