Hiwatt Bulldog 77 Bass 1x12 Combo Amplifier, 100 Watts

Hiwatt Bulldog 77 100W Bass Combo Amplifier

The Hiwatt Bulldog 77 100W Bass Combo Amplifier combines an analog solid-state preamp with a 12" Octapulse Sonic Gold speaker, 4-band EQ, and a bypassable limiter. Designed for bass guitar, it provides passive and active instrument inputs plus direct-output connectivity for rehearsal, recording, and live performance rigs.

The front panel provides Gain and Volume controls alongside Bass, Low Mid, High Mid, and Treble EQ, giving bassists more control over the midrange than a conventional 3-band tone stack. A switchable limiter helps manage signal peaks, while separate passive and active inputs accommodate different pickup output levels. An auxiliary input and headphone connection also support personal practice.

For stage and studio integration, the Bulldog 77 includes a balanced XLR output with Ground Lift, a 1/4" Line Out, and a 4-8 ohm external speaker connection. The birch-ply cabinet houses a specially voiced 300W-rated Octapulse driver, providing speaker headroom beyond the amplifier's 100W output rating in a compact 1x12 bass combo format.
