User Reviews

VB3m is praised for its authentic Hammond-era sound and Leslie simulation, with many reviewers highlighting its convincing tone, percussion, and performance realism. Reviewers laud the app's flexibility, responsive controls, and the ability to add the same Leslie emulation as the desktop version on iOS. The value proposition is strong, with affordable pricing and portability ideal for live use. Common requests focus on enhancing workflow: saving drawbar registrations and MIDI mapping, expanding presets, and offering more Leslie options and tweaks. Occasional bugs and reliability concerns are noted by a few users.
Pros
  • Extremely authentic Hammond tone and Leslie emulation, with convincing percussion.
  • High praise for flexible controls and polished programming.

Cons
  • Lack of saved drawbar registrations and no easy MIDI mapping to trigger presets.
  • Desire for more built-in presets and easier preset management.
  • Occasional bugs or reliability concerns (e.g., sound getting stuck) and reports of limited developer responsiveness.

VB3m is great. Sounds almost like my A100. I run it thru a Pro3T rotary, and it’s excellent. If you want more features get VB3-II of course, but the one thing I’d love to see ported from VB3-II to VB3m is the parametric EQ. I have just a limited frequency range that needs to be tamed when 3rd harmonic percussion is active, and it would be far better to do it in the app than via external EQ. I’d gladly pay another five bucks to get that upgrade.

Just amazing. Nothing else like it. Always been a fan of the Apple GB organ but the flexibility and controls of the VB3m are on a completely other level.

Been waiting for this emulation have used just about every vest and iOS clone and this is the boss is there any discount for upgrading to the granddaddy vib3 2 but if not I’ll make this app my fav till I can afford the next level. I do have a B2 with trek percussion but this is sooo good I hardly use it
