The Sojourn 4 Acoustic Travel Bass has a remarkably big sound for such a small instrument. The secret to its great acoustic tone is the solid Engelmann Spruce top and the facts that with its 24.5" scale it performs very well in standard tuning. With the Sojourn there is no need to transpose your music to a higher key. This bass delivers right out of the gig bag (which is included with purchase). But it doesn't stop there. Hidden inside the sound hole is the B-Band® A1.2 Preamp. The A1.2 has superior frequency response with 24 dB of gain, making a perfect fit with the included B-Band® 22R UST (under saddle transducer). The sound reproduction is amazingly pure and clear. You will not believe how big this little bass sounds when plugged into a bass amp or direct to recording console or PA. Gig bag included.
