This used Swart MOD84 Black 1x12 is a hand-wired, all-tube boutique combo and was Swart’s first EL84-based amplifier design. Rated at approximately 15 watts, the MOD84 features a push-pull, high Class A–biased AB circuit that delivers rich harmonics, dynamic response, and a smooth transition from sparkling cleans to thick, touch-sensitive overdrive.

The MOD84 uses twin EL84 power tubes with tube rectification (GZ34 or 5Y3) for natural compression and bloom, along with a premium hand-wired, point-to-point layout. The interactive 3-way EQ switch, Hi/Lo inputs, and top-mounted controls make it extremely versatile and easy to dial in for different guitars and playing styles. Lush tube-driven spring reverb and tube tremolo with custom speed sweep and depth complete the classic Swart sound.

Housed in a solid, finger-jointed pine cabinet and finished in black covering, this 1x12 combo delivers boutique tone, vintage feel, and road-ready construction in a manageable size.
