The Rocktron Prophesy II Guitar Preamp with Effects is the single most powerful and sophisticated guitar effects system available today. It's comprised of 3 complete processors in 1. With dual 24-bit, 66MHz DSP processors providing 130mips of processing power, the preamp section features 4 channels: Clean American, Texas Blues, Vintage British, and Mega Drive”each with its own distinct voicings to provide a vast array of tube amp sounds. In addition, every Prophesy II preset offers a parametric pre-EQ, a parametric post-EQ, and a parametric global EQ which effects all presets at the same time. The pre-effects section features way, compression, HUSH, and an assignable pre-effect of your choice. The post-effects section provides ultratransparent, high-quality effects which completely preserve the tone of the preamp. An ADSR (attack/delay/sustain/release) function features Rocktron's pluck detection, which allows you to configure any parameters to be controlled dynamically by each pluck of a guitar string. Other features include an assignable effects loop, a bypassable preamp section, assignable effects order, a built-in tuner, a tap button, stereo XL recording outputs, true delay spillover, MIDI volume control, front and rear instrument input jacks, and more.
