Message: [QUOTE="Shamiso, post: 92445, member: 160"] Baggs lists HiFi DNA for steel-string and 12-string acoustics, while explicitly saying the system is not recommended for nylon-string guitars. The standalone system costs $299 and is now listed by Baggs as available, so retrofitting an existing acoustic is no longer just a future option. Sweetwater was still showing preorder status when checked, which is worth knowing before assuming every dealer has stock. Compatibility is the less glamorous part. Baggs requires professional installation and warns that some guitars simply will not accept the system because there is not enough room inside, a previous pickup has altered the bridge plate, or an older bridge plate has deformed. A guitar can look completely normal from the outside and still fail the fit check. The sensors themselves use adhesive rather than permanent glue, and Baggs says they do not require drilling or modification of the bridge or saddle. Placement still matters enough that the kit includes a mounting jig, extra adhesives, wire clips, soundhole controls, and the prewired electronics. Baggs' [B][URL='https://patents.google.com/patent/US20240347029A1/']soundboard pickup patent application[/URL][/B] also describes adhesive-mounted transducers on the underside of an acoustic instrument soundboard, which puts some useful technical context around this style of installation. [HEADING=2]The bridge plate decides whether the install works[/HEADING] HiFi DNA uses two lightweight sensors positioned around the bass and treble sides of the bridge plate. Each feeds its own preamp path before the signals are combined, so the physical sensor positions are part of the system rather than a casual stick-them-anywhere detail. The mounting jig exists for a reason. A clean bridge plate gives an installer the straightforward case. Trouble starts when an older pickup installation has changed the available surface, left the relevant area unsuitable, or the bridge plate itself no longer presents the shape and space the system expects. Baggs specifically calls out previous bridge-plate modifications and deformation in some vintage guitars as reasons an installation may not work. This is where the phrase “non-invasive installation” needs a little restraint. It describes a design that avoids modifying the bridge or saddle for the sensors, not a promise that every acoustic can take the system without inspection. Anyone buying the pickup before checking the inside of a heavily modified or older guitar is basically doing the process backwards. The original [B][URL='https://goldmidi.com/community/threads/gibson-and-baggs-have-built-a-hifi-dna-acoustic-pickup.77763/']Gibson and Baggs HiFi DNA pickup[/URL][/B] announcement focuses on the new sensor design, split processing, and live-sound goal. Retrofit compatibility is a separate issue because the aftermarket system has to work with whatever history your guitar already has inside it. Old repairs and old electronics suddenly matter. [HEADING=2]Twelve-string support is real, but nylon support is not[/HEADING] Twelve-string owners are not automatically excluded. Baggs lists HiFi DNA as compatible with 12-string acoustics and notes that the sensors may need to be installed with their wires facing the opposite direction, with the troubleshooting material covering the altered orientation. Gibson is also selling a J-45 Standard 12-String with HiFi DNA from the factory, so this is not theoretical compatibility. Nylon-string guitars are different. Baggs marks HiFi DNA as not recommended for nylon-string instruments, even though the company sells other pickup systems with dedicated nylon-string versions. An Element or Anthem variant built for nylon is therefore a different proposition from forcing HiFi DNA into a guitar it was not specified for. The distinction matters because “acoustic guitar pickup” is too broad a label here. Steel-string, 12-string, and nylon-string guitars can all be acoustic instruments, but Baggs does not give HiFi DNA the same compatibility claim across those groups. Buying on the product name alone can put you on the wrong side of the spec sheet. [HEADING=2]Professional installation is part of the product[/HEADING] Baggs does not frame professional fitting as a friendly suggestion. Its support page says the pickup must be professionally installed and adds that the company does not provide installation advice or support for home or hobbyist installs. Pretty clear. The supplied jig and peel-and-stick sensors can make the job look deceptively simple in photos. A competent installer still has to inspect the bridge-plate area, confirm clearance, place the two sensors correctly, route the prewired system, mount the soundhole volume and tone controls, and accommodate the 9V battery system. HiFi DNA is rated for more than 260 hours from that battery, so access for future replacement also belongs in a sensible installation. A good fit check therefore happens before money changes hands or adhesive touches wood. On a normal steel-string with a clean, usable bridge plate, HiFi DNA is designed to be a low-impact retrofit. On a vintage guitar with bridge-plate distortion, an instrument carrying evidence of previous pickup work, or a nylon-string model, the answer can change before anyone plugs in a cable. [/QUOTE]
