That's interesting because I find it far easier to be consistent (particularly at speed) with a pick, in tone and volume.I have one on my pedalboard, but it only comes on for songs where the tempo is fast and I have walking lines, or fast moving parts. When the pace picks up, or its a song that needs a pick I feel like I have less control over the notes, so I engage the compressor. Even then I have it set where it only engages with peaks.
Guess because that's where I came from with guitars so it's more natural for me.
