Nine standard VOX effects indispensable for any guitarist are built-in. These include auto wah, compressor, phaser, chorus, flanger, tremolo, rotary, delay and reverb. With the addition of combination-type effects, you have a total of eleven VOX effects to choose from on your AD15VT and AD30VT. Each effect lets you adjust several parameters. There's also a Tap button that makes it easy to set the delay time or modulation speed
