Vox Tonelab ST

Pros:

More authentic and organic tones than the Line 6 units

excellent build quality (roadworthy)

compact

very good value for money

wide range of quality, realistic tube sounds

quality effects and preamps

Cons:

noise reductor not as good as on my Ibanez TK999 pedal

pinched harmonics not as clear as on TK999 ( they sound a bit 'stunted' on the Vox. Same on the Vox Cooltron pedals)

I wish the Tonelab had a tube preamp too, beside the tube power amp (which is great).

Conclusion: not perfect, but still the BEST amp modeller out there, in my opinion far more organic and natural sounding than Line 6, and I am a tube amp maniac so I know what sounds good and what doesn't. Recommended buy.
