Get to know them!

Continuing their line of effects pedals designed to render keyboardists obsolete (just kidding), the Electro-Harmonix Synth 9 Synthesizer Machine pedal allows you to coax classic synth tones from your guitar or bass. And it doesn't require a special pickup system either — just add it to your pedalboard like any other effects pedal. Nine presets give you access to some of the most iconic synth sounds from the '70s and '80s. And thanks to an extremely wide playable range, the Electro-Harmonix Synth 9 pedal delivers precise tracking with both guitar and bass.

Precision tracking across a wide playable range

Just like the Electro-Harmonix B9, C9, Key9, and Mel9 emulation pedals, the Synth 9 Synthesizer Machine boasts ultra-precise tracking for glitch-free performance. The playable range is huge — it'll track accurately on your guitar all the way up to the 23rd fret on your high E string. On bass, the Synth 9 tracks accurately all the way down to your open A string.

Electro-Harmonix Synth 9 Synthesizer Machine Pedal Features:

  • Synthesizer emulation pedal with 9 presets for electric guitar and bass
  • Precision tracking from the 23rd fret on a guitar's high E string, down to the open A string on bass
  • Separate Dry and Effect outputs allow for dual amp setups
  • CTRL1 and CTRL2 knobs offer preset-dependent controls such as filter envelope depth, voice intervals, and more
  • 9-volt power supply included

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.
