Rich Analog Phasing for Guitars and Synths

Get to know them!

The Dreadbox Lethargy analog 8-stage phase shifter pedal delivers fat and chewy phase effects for guitars and synthesizers, complete with three patch points for modular synthesists. Choose from two LFO waveshapes to shape your modulation, with LFO rates up to 110Hz for truly chaotic effects. Guitarists at Sweetwater especially dig the Manual control, which allows you to set a fixed phase shift amount instead of LFO modulation for a cocked-wah kind of effect. You can also dial back the Feedback control to discover a vibrant analog vibrato effect. Whether you’re looking for subtle or extreme phasing effects, you’ll be impressed with the creative potential lurking within the Dreadbox Lethargy phaser pedal.

Dreadbox Lethargy Analog Phase Shifter Effects Pedal Features:

  • 8-stage analog phase shifter for electric guitar and synthesizers
  • 3 patch points for integration with modular synthesizers
  • Wide-ranging LFO, from several seconds up to 110Hz
  • Choose from triangle or square LFO shapes for 2 distinct modulation styles
  • Dial feedback all the way down for use as a vibrato effect
  • Turn off LFO modulation to control phase shift with the Manual knob
  • Requires 9-volt DC power supply (sold separately)

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
