I have modified this pedal further by drilling a hole so the internal switch can now be accessed (I made a cap to fit) giving you the option of both script and block phaser sounds just like the EVH signature Phase 90. The difference is subtle, but I find the block mode (button out) has more cut which helps humbuckers cut through, whereas the script mode (button in) is warmer and smoother which I really like with single coil pickups. Sounds great like a Phase 90 should! My favourite phaser, but I have 3 of them so I m letting this one go! Good condition with a few cosmetic marks from use but missing two bottom plate screws. Works perfectly. No box or papers.
