You missed it!


Classic 70s phaser in near mint condition, complete with box and manual.

These 70s phasers have a fabulous lush warm sound and just three switchable settings. We’ve sold a lot of these pedals and this one sounds rich and vibrant.

Serviced and calibrated.

The condition is excellent with only a few scuffs and scratches. Power switch looks to be a replacement.

Comes with an original box which is worn with a hole in the top where the replaced on/off switch has pushed through. Please see detailed photos to assess condition for yourself (click the photo to see a larger image). 

This pedal is in excellent working order – no noisy switch issues.

(Please note: it is always possible with vintage equipment that some crackly pots/sliders may develop over time when equipment has not been used – even during shipping – this can usually be easily rectified either by use or with a bit of switch-cleaning spray).

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.


  • It is a 110v model.
  • A step-down transformer is required in the UK/EU.
  • We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required.
