Marshall just introduced its very first party speaker, the Bromley 750. It looks a whole lot like a guitar amp, which makes sense given the company's pedigree. Also, instrument amps are basically just big speakers anyways.This Bluetooth speaker includes a replaceable battery that allows for more than 40 hours of use before requiring a charge. It produces 360-degree stereophonic sound that Marshall says will "find its way through any crowd." It also features a "sound character knob" that changes the tone from clear to punchy, the former being great for indoors and the latter for outdoors.To that end, the speaker features an IP54 water-resistance rating, so it can handle some rain. It also includes integrated stage lighting, which is pretty neat, and built-in handles and wheels for transport. This is a Marshall speaker, so there are two combo jacks for mic and instrument inputs.The Bromley 750 is available for pre-order right now, but there's a major caveat. This thing is expensive, clocking in at $1,300. It'll be available at select retailers on September 30.This article originally appeared on Engadget at https://www.engadget.com/audio/speakers/marshalls-first-party-speaker-unsurprisingly-looks-like-a-guitar-amp-191509061.html?src=rss
