As soon as I plugged this baby in, I knew I was in for a treat. The preset that comes up first is a fantastic lead guitar sound. With the fat richness of a tube distortion minus the blunted edge that plagues most digital imitations of tubes, this preset shows that Boss has mastered the first step to great guitar tone-good distortion.
A press of a button lets you choose between 48 different models of preamp sections of famous amps, which appear on an easy-to-read lighted LCD. Each preamp model can be tweaked by gain, three-band EQ, presence, and level knobs. And you can set up three channels just like a real amp, each accessible with a press of a button. Comp, overdrive, delay, chorus, and reverb sections all activate at the touch of a button; and the large jog wheel takes you through types of the chosen effect. FX-1 and FX-2 sections let you jog through wah, guitar synth, limiter, enhancer, defretter, phaser, flanger, ring mod, humanizer, harmonist, and octave to name just a few.
Saving patches couldn't be any easier and you get 100 user-definable plus 100 presets. A pair of reference speakers built into the housing is very handy for helping you locate patches and tweak effects as well as avoiding the typical playback latency from computer recorders. Four assignable direct-access buttons let you set up for live performance and an onboard tuner provides precision chromatic tuning. A Quick FX button lets you access optimal effect settings for quick setups on the fly.

They've been around awhile - got mine for $103 including shipping from Ebay. MINT with all discs, manuals, cords, etc.. It's in a word - AMAZING. Not just a Multi-Effects System (a Boss calls it) but a USB DI/Interface that sounds utterly PRISTINE (24-bit, 44.1kHz). It Will take me forever to learn all the features. I have tried (and own) a few different interfaces - both USB and Firewire - and I can throw em all away as this baby is king! Also basically every Boss Pedal made too.



With Built-in MIDI - simply add a FCB-1010 Footboard and it's ready for Giggin' ... I own Guitar Rig 3, most of the Amplitubes/X-Gear, Overloud's TH1.1 and a few others but I don't need any of them really as this thing has it all built-in.
