Electro-Harmonix B9 Organ Machinechat_bubble_outlineFrom real comments

With the right technique, the B9 produces startlingly convincing organ tones. Multiple users describe fooling listeners entirely, from church congregations thinking a new organ player joined, to solo recordings mixed with harmonica or banjo that sounded like a real organ. Commenters emphasize that success depends on playing like a keyboardist rather than a guitarist: sparse triads, Travis picking, glisses instead of bends, and a heavier, more consistent right hand. Reviewers who ignored this and played guitar licks were less impressed by the results.

It's a powerful tool for filling out a band's sound without a keyboardist. Several gigging musicians describe routing guitar and B9 organ signal to separate amps or PA channels, effectively turning a duo or trio into a fuller-sounding band. Users mention tackling songs that normally require a keyboard player, layering acoustic, electric, and organ tones live, and using it to replace or supplement a bass presence. The versatility to blend dry and wet signals is repeatedly called a major strength.

It falls short of a real Hammond/Leslie rig and can be finicky to use. Experienced Hammond players point out missing adjustable drawbars, true Leslie fast/slow switching, separate upper/lower manual settings, and authentic key click, calling it a decent approximation rather than a replacement. Others found it extremely sensitive to picking dynamics, making consistent tone hard to achieve, and a couple of long-term owners reported the organ-type selector becoming unreliable after months of use.
