The uniquely designed DD3X Double Drive 3X Distortion Pedal from Tech 21 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 variations. 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.

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.
