mini pedal or big brother
Even full size pedals provide more flexibility to control the tone and they can do stereo job, I still feel they are not necessary. Typically, I set reverb to the end of my chain (except looper), so for me, HOF is the only one pedal worth the stereo setting, right?
On the other hand, I feel modulation pedals are quite similar, does it mean there is no necessary to get all of them? It seems you can simulate modulation effects via toneprint.
