I don’t use any pedals. Back in the eighties when I started on bass, I used a comp and a chorus. That was a thing back then. I’ve been playing acoustic music for the last ten+ years. I also play mandolin and acoustic guitar. When I choose a mandolin, mandola, guitar, or baritone guitar, I choose it based solely on how it sounds unplugged, purely acoustic. Because if it doesn’t sound good that way, it’s never going to sound good, and plugging it into all the pedals or big amps in the world ain’t gonna make it better. It’s similar with a bass. If it doesn’t sound good to me without a pedal or effects on an amp, it ain’t going to get any better with. I either get that sound with the wood and the wire and the fingers, or I find another one. The amp is only there to increase the volume of the intrinsic sound of the bass.
I realize others play different kinds of music, and that’s fine, I’m not judging, I’m only relating what works for me.
