Kush AudioREDDI
$49
The original hardware REDDI is a legend among professional session players and commercial studio owners. Its hybrid tube/solid state gain circuits, beefy transformer, and oversized power supply have an uncanny ability to both rein in bass transients and punch them up.
LR BAGGSBuilt on our decades of experience in designing DIs, the Align Active DI features some of the most pristine and transparent circuitry we’ve ever developed.
LR BAGGSIn 1995, the Para DI changed history by becoming the first-ever preamp/DI designed specifically for acoustic instruments.
LR BAGGSMost players dream of making their acoustic guitar sound the same as their favorite record, but those professional studio tools weren’t designed for live performance…until now.
LR BAGGSMost electric bass players are all too familiar with plugging directly into the PA and getting a flat, uninspiring sound from the speakers. The Stadium DI was designed by our bass-playing engineering team to solve that live-performance problem.
LR BAGGSBuilt on the shoulders of the legendary Para Acoustic DI, the Baggs Venue DI puts you in the driver’s seat of your own sound, in any venue. Guitarists know they will face unpredictable stages, from faulty monitors to questionable house PAs, and the constant threat of feedback.
LR BAGGSSince the beginning of acoustic amplification, musicians have been forced to sacrifice the complex sound of their prized guitars to play at louder volumes. You could use a mic to capture detail and suffer feedback, or use a pickup for higher volumes at the expense of your guitar’s true voice.
