The Redshift Deluxe Phaser is based on the Blackout Effectors Whetstone Phaser, originally released in 2009 and discontinued when Blackout closed their doors in 2018.
The Whetstone was based on the Electro-Harmonix Small Stone, a classic OTA phaser, but with several modifications including additional controls and switches and an output gain boost to solve the level-matching issues in the original. It also replaced the obsolete CA3094 OTA with the LM13700, essentially a dual version of the chip with somewhat improved specifications.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 5 knobs for 6,3mm shaft separately.
