Boss RPH-10 Phaser

A new-generation Boss RPH-10 Phaser with 12-stage phase-shift circuitry and recording studio quality sound. According to the mode selected, 3 completely different effects can be produced. Mode I (6 stages) is for soft and light phase-shifting, while Model II (I/O stages) creates deeper phase-shifting all the way from the lows to the highs. Mode III (12 stages) is for when a sharp and intense phasing effect is required.

Apart from the basic RATE, DEPTH and FEEDBACK controls, the Boss RPH-10 is also equipped with a MANUAL control to adjust the centre frequency around which the phase shifting occurs. With this control, it becomes easy to find a setting that is suitable for a particular instrument.

A custom IC, newly developed, is utilised in the phase-shift circuitry to produce phase-shifting which is exceptionally smooth. Although phasers usually tend to get noisy as the number of stages increases, the Boss RPH-10’s built-in noise reduction system ensures a wonderfully clear sound.

Controls

• MODE: For selecting one of the following 3 modes. Mode I provides 6-stage shifting for a mild phasing effect, while Mode II offers a deeper effect due to 10-stage shifting. Mode III is for very intense and powerful 12-stage phasing.
• MANUAL: This will select the centre frequency of the phase-shifting and helps to match the phase-shifting to the type of instrument used.
• RATE: For adjusting the speed of the phasing effect. Turn clockwise for increased speed and counterclockwise to slow it down.
• DEPTH: For adjusting the depth of the phasing effect. Turn clockwise for a deeper-sounding effect and counterclockwise for shallower phase-shifting.
• FEEDBACK: For controlling the amount of feedback signal to create a stronger phasing effect.

Having 3 different modes, the Boss RPH-10 allows the user to produce a very wide array of effects, from the sharp and intense to a soft and light effect. Effectively employing these 3 modes will allow the Boss RPH-10 to display its full potential.

Above you see the setting utilising Mode I to produce a phasing effect which is shallow and natural sounding. An ideal setting for electric piano, one that delivers an open, wide type of sound with a slight emphasis on the highs, you’ll find it often used by Richard Tee. Mode 11 is used below to create deeper phase shifting, an effect that really puts synthesiser lead solos in the spotlight It’s also effective for guitar backing where muting is used. By setting RATE to a slightly lower position, you have the perfect sound for reggae cutting. With Mode Ill, a deep and very intense phasing sound is affected by taking full advantage of the 12-stage phase circuitry. It’s a setting that really adds sparkle to synthesised strings with the RA TE control lowered just a bit.
