A super compact amp with a ton of clean power, weighing in at under 5 lbs., perfect for players who don’t like lugging a 60 lb. head around. As incredible as it sounds, this little powerhouse delivers 1000 watts through 2 ohms (800/4 ohms), via one or two Speakon speaker outputs. Although marketed as primarily an upright or electric bass amp, some jazzers have found it capable of handling jazz guitar duty. The Focus does not color your tone like most amps – what goes in is what comes out – it accentuates the *acoustic* tone of your instrument rather than the pickups. For bass, it’s equally at home with electric or upright basses. Features include extended frequency range, high fidelity sound via Class D (PWM), unique slanted front chassis with built-in handles on side rails, combo jack input (either 1/4″ or XLR), phantom power on XLR input, 3-band EQ preamp (±15 dB @ 60 Hz, 650 HZ, ±15 dB @ 650 Hz, ±25 dB @ 10 kHz), Notch Filter (-18 dB sweepable from 30 to 800 Hz), Low Cut Filter (-12 dB/octave sweepable from 30 to 800 Hz), parallel effects loop with return level control, EQ post/pre switch, separate input and master level controls, quality XLR D.I. output, ground lift switch, mute switch, light weight (5 lbs), small size (10.2 x 8.2 x 3.5). 1000W through 2 ohms, 800W through 4 ohms, 450W through 8 ohms. Acoustic Image owners swear by these amps for the sound quality, build quality, and lifetime warranty that’s transferable to new owners. From what I’ve read on the web, in the rare case it develops any problems, just ship it back for repair (and frequently upgrade to current specs) and it’ll be fixed for free, including return freight. You can’t get better than that. For more info click here and read specs on the Focus 1 here and here. Sells new for $1179 but this clean used one’s a great deal at just $650. Includes well-padded gigbag and Speakon speaker cable.
