How we ranked these synthesizers

Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Keys weight 2
Max polyphony weight 3

Buying advice: synthesizer for bass

Pick analog or analog modeling

True analog circuits (the TD-3-AM, TD-3-MO and Bass Station II list VCO and VCF designs) shape bass with voltage-controlled oscillators and filters. Analog modeling (the MiniNova) recreates those circuits digitally with 18-voice polyphony. For classic bass lines the true analog picks match the search; for bass plus leads, pads and a vocoder, modeling covers more ground.

Match the keys to your setup

The MiniNova has 37 mini keys and the Bass Station II has 25 full-size keys with aftertouch. If you play parts by hand, the keyed Novations fit. If you program patterns, the Behringers' 16-step sequencers and the PO-14's 16 pattern chains do the job. Think about which workflow you already use before choosing.

Check connections and power

USB-MIDI appears on the TD-3-AM, MiniNova and Bass Station II; the TD-3-MO adds MIDI In/Thru plus USB 2.0 and 1/4-inch and 3.5mm jacks. The PO-14 runs on 2 AAA batteries with a 3.5mm line out for headphones or a speaker. Match the outputs to what you already own: a mixer, an audio interface, or just headphones.

Frequently asked questions

What is the best synthesizer for bass lines?

The Behringer TD-3-AM leads this list: true analog VCO and VCF circuitry with a 16-step sequencer made for bass lines, at 1.8 lb with USB-MIDI.

Do I need full-size keys for bass synth?

No. The Bass Station II has 25 full-size keys with aftertouch, but the Behringers center on 16-step sequencing and the PO-14 on 16 pattern chains. Choose keys if you play by hand, or a sequencer if you program.

Can a pocket synth handle real bass parts?

The PO-14 Sub is built for it: 15 sounds, 16 punch-in bass play styles and 16 punch-in effects in a pocket synth. Use the built-in speaker or the 3.5mm line out for headphones or a speaker.

Analog or analog modeling for bass?

Both work. The TD-3-AM, TD-3-MO and Bass Station II use true analog VCO and VCF circuits. The MiniNova uses analog modeling with 18-voice polyphony and 256 presets for bass plus more.
