he ZON PEBX combines the musical EQ curves of early Portastudio and M-series compact mixers with the raw, crunchy gain topology of classic 'BX' series utility consoles. Created by the team behind ALM Busy Circuits, the PEBX brings authentic 1990s house and techno grit with subtle harmonic squish into a standardised 500 Series module. Pushing the input gain introduces the signature character, saturation, and noise profile of vintage BX preamps. To manage the increased signal output, a dedicated output level attenuation control allows you to drive the circuit hard while scaling down levels. Key Features Portastudio & M-Series EQ Topology: 3-band EQ tuned for wide, musical frequency shaping on drums, acid synth lines, and bass lines. BX-Style Input Gain Stage: Delivers unity to +20 dB of drive to introduce organic crunch, compression, and harmonic saturation. 3-Band Frequency Control: Fixed 10 kHz high shelf, sweepable mid (1 kHz−8 kHz), and sweepable low (60 Hz−1.5 kHz) with ±12 dB boost/cut per band. Output Level Attenuator: Matches output levels after applying high input gain or extreme EQ boosts. Clip & Bypass Status LEDs: Clip indicator monitors input overload, paired with a latching hardware bypass switch for easy A/B comparison. Handcrafted in the UK: Standardised single-slot API 500 Series module format.
