BULLHEAD 1.5K

The Bullhead 1.5K started with the front end of the 3K — the preamp, the EQ, and the filters — and simplified the concept. A single input feeds the preamp, a single power module drives the output, and two parallel speaker jacks put it to your cabinets. No dual-channel routing, no secondary inputs. Just a high-powered head designed to do one thing well.

The Mike Pope-designed Bullhead preamp is the same across every Bullhead head. Warm, transparent, and precise, it gives you an accurate picture of your instrument with as much or as little shaping as you want. The 4-band EQ covers Bass, Low Mid, High Mid, and Treble — shelving controls on the lows and highs, bandpass on each midrange — all with selectable frequencies and ±12dB of range.

The 1.5K’s front panel includes the same variable High Pass and Low Pass filter section found on the 3K. Both are independently switchable, and both provide a steep 24dB per octave cut when engaged. The High Pass sweeps from 38Hz to 310Hz — useful for controlling how much low-end energy reaches your cabinets. The Low Pass sweeps from 330Hz to 15kHz, letting you soften the top end of the signal as needed. Between the two filters, you can dial in the exact frequency window of the amp without disturbing the tone inside it.

High Pass/Low Pass Filters

Just like the 3K, the 1.5K features the same defeatable, variable High Pass and Low Pass filters, located on the top left of the front panel. When engaged, each filter delivers a steep 24dB per octave cut — the HPF trimming below your target frequency, the LPF rolling off above it — giving you precise control over the full width of your frequency range. The High Pass can be set anywhere between 38Hz and 310Hz to manage low-end content, while the Low Pass can dial in from 15kHz down to 330Hz to reign in the top end. Together, they let you shape the 1.5K’s wide, full-range bandwidth into exactly the sonic space your playing demands, without touching the character or tone you’ve already dialed in.
