My normal chain is a noise gate, followed by a comp, a little emulated tube drive, an SVT amp model, an impulse response modeled cab simulator (of course running a 8x12 SVT cab), a plate reverb, and a limiter. I've got some crazier ones, but as a beginner bassist, that's all I really need. There are literally hundreds of effects to choose from though.

Convolution reverb is an option, but it ended up being a little more than the Pi4 could handle iirc. I didn't tinker with it much though.

Latency is under 10ms, I'd have to go back and check my settings to confirm exactly though.
