The Trickfish Bullhead .5K is a compact, powerful bass amplifier head designed for players who need professional tone, serious headroom, and reliable gig-ready performance in a lightweight format.

Built around the acclaimed Mike Pope designed low-noise analogue preamp, the Bullhead .5K pairs refined tone shaping with a tour-proven 700W Class D power section. The result is a bass head that delivers clarity, punch, warmth, and control without unnecessary weight or bulk.

The 4-band EQ gives players detailed control over their sound, with selectable frequency options across the bass, low-mid, high-mid, and treble sections. Whether you need deep lows, tighter mids, smoother top end, or a more defined modern bass voice, the Bullhead .5K gives you the flexibility to shape the amp around your instrument and playing style.

Despite its compact size, the Bullhead .5K is fully equipped for stage, studio, and rehearsal use. It includes selectable input sensitivity, aux input, headphone output, mute switch, series effects loop, balanced XLR DI output with pre/post selection, ground lift, and level control.

Housed in a rugged aluminium chassis and finished in Trickfish’s Deep Sea Blue matte powder coat, the Bullhead .5K weighs only 2.37kg, making it a highly practical choice for working bassists who want premium tone in a portable amplifier head.
