Aria Pro II SB-700 4-String Bass Guitar

Questions and answers
- Which is better for a tight low B?
- The Yamaha TRB1004J. Its 35-inch scale gives the low string more tension and definition than the Aria's 34-inch scale.
- Which has more tonal options?
- The Yamaha, thanks to its active 3-band EQ and two pickups. The Aria offers a series/parallel switch but no onboard EQ.
- Does the Aria need a battery?
- No. The SB-700 is passive, so it works without a battery. The Yamaha's active circuit requires one.
- Which is easier to play high up the neck?
- The Aria. Its heel-less cutaway and neck-through design give cleaner access to the upper frets than the Yamaha's bolt-on heel.
- Is the Aria worth the extra money?
- Its lowest daily price was $1,183.00 on November 1, 2026, and no current Yamaha price was given, so compare live prices before deciding. Pay the premium only if you want neck-through sustain and the vintage single-pickup sound.
