Description
The GFI System Rossie packs three distinct filter voices into a single enclosure, letting you swap between vocal-like sweeps, rhythmic gating, and fixed tonal sculpting without touching your board layout. It’s built for guitarists and bassists who treat filtering as a core part of their signal chain rather than an occasional effect.
- Envelope Filter reads your pick attack and translates dynamics into resonant, quacky sweeps — dig in harder for a wider sweep, back off for something subtler.
- Step Filter chops your signal into adjustable, arpeggiated steps for synth-like rhythmic patterns that lock into a groove.
- Manual Filter works as a fixed tone-shaping tool on its own, or connect an expression pedal to turn it into a wah-style sweep under your control.
Internally, Rossie runs on 24-bit DAC/ADC conversion for clean, low-noise signal handling, with a 1 MOhm input impedance and 1K Ohm output impedance to keep it transparent in a busy pedal chain. Current draw sits around 110 mA, so check your power supply’s headroom before adding it to a crowded board.
- Weight: 0.6 kg (1.6 lbs)
- Dimensions: 12 (L) x 7.2 (W) x 5.5 (H) cm
- Power: 9VDC, negative center (not included)
Whether you’re after squelchy envelope funk, stepped synth textures, or a wah on tap, Rossie consolidates three filter tools into one pedal-slot solution.
