A focused stereo headphone amp built around the same circuitry as KMA's Endgame, now available on its own for anyone who already has cab sim and tone-shaping covered elsewhere in their rig. Plug your guitar or the end of your pedalboard into the stereo input, headphones into either of two 3.5mm outputs, and you're monitoring in stereo — add a phone or tablet via Bluetooth or the 3.5mm aux input and it doubles as a practice tool for playing along to backing tracks.

An Aux Mix control blends backing track against instrument signal, with a centre detent for an even 50/50 split. The Output Mode switch determines what reaches the main stereo outputs: Full Mix passes guitar and aux signal through together (useful for recording or feeding a PA while monitoring), Thru strips the aux out entirely so only your instrument signal reaches the main outs. Input Gain runs ±24dB with a clip LED, covering everything from a low-output pickup to a hot modeller output — and worth knowing, pushing it into saturation gives a deliberately warm, console-like character rather than harsh clipping.

Auto-detecting TS/TRS connections throughout; mono input sums to both channels if only one side is connected. Bluetooth and the 3.5mm aux input are mutually exclusive — pairing Bluetooth disables the analogue aux. 1MΩ high-impedance input, 100mW headphone output into 8–32Ω, 20Hz–20kHz response.

Runs on 9V DC centre-negative, maximum 250mA. A compact, genuinely useful unit for silent practice, DAW monitoring or IEM feeds — particularly handy for ampless players needing clean headphone monitoring after a cab sim.
