Ah right
Ah right, I assumed that you already had a GT-1B!
Had mine 4 years or so. It's been great to have. Certainly good value and well built/designed. Some patches are better than others. I didn't intend it to be a replacement for (all) other pedals. So I've continued to explore/buy certain seperate pedals out of curiosity/desire more than necessity.
I feel these other pedals do a better individual job than the GT-1B. Perhaps it's trying to be too much in one unit? Weak areas for me are synth, octave, eq (low end clips out easily) , DI and extra distortion options control. So these I have individual pedals for these.
Most preamps, modulation, cab sims, wah, OD, reverb, delay are all usable.
I really wish BOSS/Roland would do a firmware update on the GT-1B, as it's a great unit to use.
