Intended for electric bass, the HD75 from Hartke is a combo amplifier capable of delivering 75W RMS. Its 1x12" cabinet houses a 12" HyDrive paper and aluminum cone driver and a 1" tweeter to boot. After connecting your instrument to its 1/4" jack, you can manipulate the signal with bass, midrange, and treble controls, as well as a 7-band graphic EQ which lets you dive deeper into specific frequencies.
The amplifier gives you 1/4" I/Os for looping outboard gear into your signal, as well as a headphone output, the use of which mutes the amplifier, and thus, enables you to practice silently through headphones. A 1/8" line-level input allows you to plug in CD players, MP3 players, or any compatible playback device, giving you the opportunity to practice along with a background track of your choice. This amplifier is suitable for use in rehearsal spaces and practice sessions.
