Tech 21 Double Drive 3X
Tech 21 NYC Logo


This unique pedal design captures the lush, muscular power amp
distortions of both Class A and Class A/B tube amps. The tones can be used individually or you can feed one into the other for massive ‘cascading’ distortion and limitless tonal variation. The 100% analog Double Drive 3X is a 3-channel, fully programmable version of its single channel predecessor and features active 3-band EQ. The expanded tone section gives you even greater flexibility to create incredible and original tones. You can store three custom sounds, even on the fly, by simply tweaking the knobs and double-tapping on a footswitch. How easy is that? And, with both Drives at minimum, you can program a clean boost up to 10dB for blazing solos.

Sometimes more is more.

Double Drive 3X MOD

The Double Drive 3X has undergone a Private Stock MOD. It has been revoiced for more aggressive hard rock and metal tones rather than classic, bluesy-style tones. It features a tighter low end and a wider Level taper. The Double Drive 3X MOD is available at the same price as the original for a limited time.


• LEVEL is capable of extremely high output, up to 10dB (even in clean setting). Useful as a “pre-boost” for additional gain out of your amp without altering any tonal characteristics.

• 1/4″ INPUT is 1megOhm high impedance input, same as traditional tube amps.

• 1/4″ OUTPUT is 1kOhm low impedance output.

• Can drive long cables without loss of signal integrity, even in bypass.

• LED is highly efficient and low power consuming. It will fade as the battery runs low (±6.5V), although the Double Drive will continue to operate.

• Utilizes standard 9V alkaline battery (not included) or optional power supply: Tech 21 Model #DC4-A.

• Power Consumption: approx. 5mA.

DRIVE A controls the amount of Class A power amp output stage distortion (like Vox AC30®-style amp), rich in even harmonics. The amount of harmonics is dynamically controlled by the input level and their ratio by how hard you pick.

DRIVE A/B controls the amount of Class A/B power amp output stage distortion (like Fender®/Marshall®-style amps), rich in odd harmonics.

The signal path of Drive A runs into the signal path of Drive A/B. This results in an electronic multiplication, rather than addition, of the amount of distortion to achieve a cascading effect.
