Get to know them!

For the gigging acoustic bass guitarist in need of volume and great tone, Guild Guitars offers the B-240EF acoustic-electric bass. The B-240EF features a solid Sitka spruce top and layered mahogany back and sides for top-notch acoustic tone plugged or unplugged. The B-240EF offers a fast-response pau ferro fingerboard and bridge, as well as a slim C-shape mahogany neck profile that feels immediately comfortable in your hands, offering great playability. Finally, a Fishman Sonitone bass pickup system kicks out gorgeous deep, low-end tone when plugged in. Acoustic-electric bassists here at Sweetwater love the Guild B-240EF for its playability and affordability.

Discreet Fishman Sonitone pickup system for performing live

The Fishman Sonitone pickup system not only provides exceptional acoustic amplification, but the design of the Sonitone system is also discreet. The controls are accessed via the soundhole, so you won't have a bulky preamp and tone-compromising hole cut into the side of your instrument for the sake of getting a good live sound.

Engineered for a comfortable playing experience

The Guild B-240EF is engineered from the ground up to be comfortable and effortless to play. You'll notice the slinky-smooth string action along the 30-3/4" scale length, C-shaped neck. And the 1.625" nut width spaces the strings wonderfully for playing fast bass lines without feeling cramped or having to reach uncomfortably far for your next string.

Guild B-240EF Acoustic-electric Bass Guitar Features:

  • Jumbo body design for great volume and bass presence
  • Solid Sitka spruce top provides exceptional tone
  • Fishman Sonitone bass pickup system kicks out gorgeous deep, low-end tone when plugged in
  • Bone nut and saddle provide great tonal support and enhanced resonance
  • C-shaped mahogany neck profile that feels immediately comfortable in your hands
  • Great live tone with the Fishman Sonitone system
