I have a small pedalboard (Pedaltrain Metro 16) with 6 effect pedals + 2 controllers. Signal chain is: Sonic Research Turbo Tuner>Wampler Mini Ego compressor>Hudson Broadcast>Rockett Rockaway>Chase Bliss Tonal Recall>Neunaber WET reverb. A Chase Bliss Faves midi controller is connected to the Tonal Recall and a Neunaber EXP controller is connected to the WET reverb. Only the Faves needs 9v power and it's daisy chained with the Tonal Recall. All these pedals are true bypass except for the Tonal Recall which can be set for trials and the WET reverb which is buffered bypass only and it's the last pedal in the signal chain. I have a little empty space in my pedalboard (the size of a Polytune mini) and I was thinking about putting a buffer first in the chain so I can have a buffer at the beginning and a buffer at the end of the chain (WET). Is it necessary? If so, do you have some mini buffers to suggest?
