John East Uni-Pre 4 Knob Black
John East Uni-Pre 4 Knob Black
The Uni-Pre 4 Knob is a new generation bass preamp system from East UK. It’s a brand new design, that sets new standards with unique features - aiming to fit virtually any bass with 4 knobs and rear cavity electronics. The modular construction makes for an easy installation - with simple plug connections between modules. External wiring, such as pickups and power are simply connected using screw terminals. The volume/blend has totally independent dual active and passive signal paths, controlled simultaneously with a conventional knob set. The EQ module allows an internal voicing adjustment for the treble, as well as lower and upper bass frequencies. This is in order to allow finely tuned focus on the most crucial bass spectrum.
• Bass: +/- 18 dB cut/boost with an internally adjustable frequency filter
• Lower Frequency Filter 20 - 80 Hz
• Higher Frequency Filter 40 - 200 Hz
• Mids: +/- 14 dB cut/boost with a frequency sweep of 100 Hz - 2.5 kHz
• Treble: +/- 18 dB with internally shelf frequencies of 1 kHz - 7.5 kHz, pull/bright peaking at 10 kHz
• Pre-Shape: a gentle lift at lower and higher frequencies, peaking +4 dBs at 40 Hz - 10 kHz
• incl. black knobs
