Service on a rare Colorsound pedal
Just love the looks of these old pedals.
The outside consists of three knob, bypass switch for the Fuzz and a treadle for the speed and bypass of the phaser.
Inside the case there’s two separate circuit boards stacked. One for the fuzz and the other for the phaser.
Top circuit holds the phaser, appears to be a four stage phaser.
Bottom side of the phaser cicrcuit board.
The Fuzz circuitboards. A three transistor circuit, a pair of diodes back to back. A Colorsound Jumbo tonebender?
Bottom side.
The issue with the pedal is the phaser, sounds weak in its phasing. The old tantalum capacitors where replaced, the fets bias was recalibrated and the depth was adjusted. Now it sounds as good as new.
