Critic Reviews

Guild’s B-240EF | Vintage Guitar® magazine

vintageguitar.com

The Guild B-240EF Fretless Acoustic Bass offers an unexpectedly premium playing experience for its price, showcasing a solid Sitka spruce top and warm mahogany body that deliver deep, resonant tones. Perfect for coffeehouse gigs or intimate jam sessions, it effectively mimics the sound of a stand-up bass. However, players should note the roundwound strings may limit the classic fretless vibrato style, and transitioning from a fretted bass could require adjustment. Overall, this bass stands out as a fantastic bargain, providing quality and versatility that might make traditional fretted players envious.
