Boss BR-800
A battery-powered studio that fits in a gig bag - four XLR inputs, onboard mics, and a rhythm engine borrowed from the DR-880.
Overview
The BR-800 is a digital recorder that lets you grab a quick idea and also cut a real track. Boss built it around SD card media. The spec sheet reads like a wishlist for the traveling songwriter - simultaneous 4-track recording with 8-track playback, plus a dedicated stereo track reserved for the onboard rhythm generator. Drum and percussion parts live on their own track instead of eating into your audio count, so a four-piece band can track live and still have room for a rhythm bed underneath.
Four XLR mic inputs sit on the front panel, and one of them offers phantom power for condenser mics. That's a generous input count for a battery-powered unit. Most portable recorders in this class give you two decent preamps, or a single input and a lot of menu diving. Boss also built in two condenser microphones for grab-and-go tracking. The unit runs on batteries, and with the onboard mics and SD storage a song idea can go from hummed to tracked without a cable in sight.
The rhythm generator is where Boss's drum-machine heritage shows. It's described as DR-880-quality, and the DR-880 is a dedicated drum machine, not an afterthought bolted onto a recorder. For songwriters who sketch with a beat, having that engine in the same box as the audio tracks removes a layer of sync headaches. EQ Magazine (June 2010, p.18) highlighted the rhythm generator as one of the unit's defining features, noting that it adds drum and percussion tracks directly to songs without a separate device.
Effects are handled by COSM modeling, and the BR-800 pulls from several corners of Boss's catalog. Vocal models come from the VE-20, and there are COSM guitar and bass effects plus modeled acoustic-guitar body effects. That's a lot of processing at the tracking stage. Committing to a modeled acoustic body on the way in is a decision you can't undo, so treat the effects as a tracking tool and not a safety net. The VE-20-derived vocal processing means a solo performer can get a finished-sounding vocal take without outboard gear.
Connectivity goes well past the SD card. Connected to a PC, the BR-800 works as a USB audio interface, and it can record to the computer while still using its internal effects. The processing doesn't get bypassed when the unit becomes an interface. It can also act as a control surface for DAW software. Boss bundled Cakewalk SONAR 8.5 LE along with audio loops and backing tracks, so the box arrived ready for a computer-based workflow without the buyer supplying their own software.
Pricing varied by source. EQ Magazine (June 2010, p.18) listed the BR-800 at $525 MSRP, while an earlier Electronic Musician write-up put it at $449. The gap likely reflects list versus street pricing or a change over the model's run, so treat the lower figure as the more realistic street number.
Two convenience features show how Boss expected the unit to be used. The Retry function re-cues automatically to fix mistakes. That only makes sense on a device built for solo, self-engineered sessions, where you're performer and engineer at once and every trip back to the controls costs you time. Song Sketch recording offers instant one-touch capture, so you don't have to navigate menus when an idea arrives. EQ Magazine (June 2010, p.18) singled out both the touch sensor switches and the SD-based recording as the reasons the BR-800 amounts to a battery-powered studio on the go.
The BR-800 is not a replacement for a full studio console. The 4-track simultaneous recording ceiling means a five-piece band can't all track at once, and the 8-track playback limits arrangement complexity compared to a DAW. It's a device for capturing performances away from the desk, and for that job the input count, phantom power, onboard mics and rhythm engine make it one of the more complete portable recording packages of its era. Anyone hunting one today should confirm SD card compatibility, since SD media standards shifted over the years and older cards are the safer bet for a unit of this vintage.
