Me too. Arco and pizzicato sounds are too different on my NS Design NXT EUB (arco is significantly louder).
Effects aside I think dealing with the arco/pizz sound need differential is THE reason to consider going with a pedalboard. Using separate two pickups / eq settings like I do is kind of an extreme solution but it really has helped me get the sound I need for each without any compromise. I’m essentially playing two different instruments on this gig.
Channel A is the double bass channel, eq’d for a forgiving bow response. I don’t use this channel for pizz at all. I have the reverb set pretty subtle to give me a little cushion and to blend with the other string player in our group.
Channel B is basically an electric bass channel. I will say as far as electric basses go an Eminence with Thomastik strings and a Krivo works very well and sounds great in that context. The octave pedal is run with the lower octave soloed to get me down into that five string territory, not so much to get a really “synthy” effected tone.
With this setup, I can cover a lot of sonic range and can handle extreme volume levels. I’m really pleased with the sound for this project, and really happy I didn’t need to switch to BG and give up arco!
