I own the Zoom B2.1u as well.
People slam it n00b because of the low price point they think it's beginner - I think they are just trying to justify how they paid extra $500 for a similiar product of another brand so they think they are superior. heheheh...
But no, I think the Zoom sounds excellent in it's own right. Good quality sounds and low price - bang for buck!
The tuner is excellent, damn fast, you play fast notes it can tell you every single note you play.
I love it most for the amp modelling and drive... excellent tones!!
The auto-wah and auro-resonance is extremely good as well. The chorus, phaser and flangers are ok.
The octave, pitch shift and harmoies are surprisingly good. Octave and harmoniser tracks well.
The built-in simple rhythm machine is useful.
People complain that it's hard to turn on-off effect, i don't think that's the case. Although it's build more for patch changing - means you program several different sets of effects you want then switch patch up or down.
you can still switch on / off individual effect the normal way - just turn the knob to the effect you want, then step on the left switch to toggle it on/off.
BTW for those with the Zoom, which part of the chain is it in your board?
I used to put it like this
bass->zoom->comp->tuner->amp
But now I changed the order like this
bass->Digitech Bass Synth Wah -> Bassballs -> Zoom -> Korg Tuner -> EBS multi-comp
I changed it coz I can tap on the Korg tuner to mute everything. Also The expression pedal on the zoom can be used as volume pedal at the same time this will not affect the triggering of the wahs before the zoom.
If I put the zoom before the wahs, when I use the espression pedal to turn the volume down, it also affected the wah triggerings.
I want tp try a line 6 pod.... anyone owns it and can share experience with it?
