Is overdrive, chorus, delay, etc built in?

Yes, there are 40 effects built-in including Noise Gate, Overdrive, Distortion, Delay, Modulation (Chorus, Flanger, Phaser, Tremolo..etc.) and Reverb. You can adjust effects using the control knobs on the amp, or take a deep dive into all of these features and edit your tones in the Spark app that comes free with the Spark amp.

Have you replaced the grounding issues with the power supply not being grounded? I read it causes hum issues

Hum issues can come from many places and 3 prong plug doesn't always get it. Did you try a ground lift? The electrical circuitry in your house (or whatever structure you're in) can cause hum. Florescent lights, f'rinstance. Do you have single coil pickups? find out. That's why Gibson made the "Humbucker". So many issues that wont be resolved with 3 prong plug. I'm looking for a battery powered amp like this. If it was batt powered (self contained) I would buy one and hum wouldn't be an issue (except for maybe single coils under flourescent lamps). Also, your amp may hum if don't know the lyrics.

Is it for bass guitar?

Spark is an amp for bass, electric and acoustic guitar. There are 10,000+ tones and auto chords.

Are the presets built in or do you have to buy them?

Yes, there are factory presets built into the amp itself, plus lots more you can load in from the accompanying free Spark app. You also can find thousands more presets and tones free of charge when you log into Spark ToneCloud.
