Description
Piezo pickups get the job done, but they rarely sound like the guitar you fell in love with. The Boss AD-8 fixes that at the source: run your acoustic-electric through it and COSM Acoustic Modeling recasts that thin, quacky piezo signal into one of six revered acoustic guitar voicings, including Martin- and Gibson-style tones. It’s the first processor of its kind to pull off that trick, and it goes further with Body and String Enhance controls that emulate the depth of a properly miked acoustic — no extra mic, no feedback headaches.
- COSM Acoustic Guitar Modeling reshapes piezo tone into six premium acoustic guitar characters
- Body and String Enhance controls add miked-acoustic warmth and dimension
- Reverb voiced specifically for acoustic guitar, from a whisper of ambience to full room and hall
- 4-band EQ for shaping tone to the room or the song
- Auto Anti-Feedback keeps things clean at stage volume
Place the AD-8 at the front of your acoustic rig and it doubles as command central for a live set. A TU-Series-based chromatic tuner mutes your signal at the tap of the footswitch so you can tune silently mid-song, and four onboard memory slots let you jump between saved acoustic voicings instantly — handy for a set that moves between fingerstyle and strummed tunes.
Routing is built for real venues: an Electric Guitar Amp output lets you send a separate feed to an amp, while balanced XLR outputs with ground lift go straight to a PA or interface as a true DI, sitting alongside standard unbalanced stereo outs and a headphone jack for silent practice.
Runs on a 9V PSA-series adaptor or six AA batteries (included), drawing 120mA. Housed in Boss’s familiar floor-pedal chassis at 250 x 180 x 60mm and 1.9kg.
