Phase 90 Block

Phaser

Block Logo Phase 90 reissue with brighter, more aggressive sweep, with sweeping filter modulation and resonance.

The Phase 90 Block reissues the Block Logo circuit era (1977 onward) that used TL062 dual op-amps. Block versions produce brighter, more pronounced phasing than the earlier Script Logo units. Single Speed knob controls rate. The four-stage circuit creates two notches that sweep through your frequency spectrum. The Block Logo voicing emphasizes the effect more than Script versions. Block Logo Phase 90s suit players who want phasing that cuts through a mix. Where Script versions offer subtle modulation that enhances without dominating, Block versions make a statement. True bypass switching.
