Sporting a triple LCD screen display, an onboard tuner, drum machine and 40 second looper, and a whopping 111 total amp and stompbox emulations, the Zoom B3 Bass Effects and Amp Simulator condenses the whole of a rig into a streamlined effect unit. Running up to three effects/amp simulations at once, the B3 allows for nuanced tweaking of each mode and can save up to 100 user presets in its massive storage bank. With additional USB connectivity for DAW recording and Steinberg Sequel LE Recording software for editing, this massive little beast could well be the last stop in your search for a do-it-all unit.
