Ferrofish B4000+ Organ Sound Module

Unique authentic organ sound module featuring a rugged metal enclosure, dedicated FX, and adjustable parameters for key
MFR# B4000+

Product Description

An organ expander module without controls to shape the sound would be like a guitar without a neck – it just doesn’t make sense. This is why the Ferrofish B4000+ Organ Sound Module includes drawbars and potentiometers – to provide you with the tools you need to find, control and tweak your favorite sounds in a fast and simple way.

Authentic Hammond B3 Emulation

The B4000+ recreates the full sonic bandwidth of the Hammond B3 organ, including all of the functions and features that made the original so special – without the weight of course! Housed in a rugged metal enclosure, the B4000+ features dedicated FX, adjustable parameters for key-click, percussion and even the aging of the tone-wheels. All of this makes the B4000+ an authentic Hammond emulation, with full-bodied bass, defined midrange, and highs with the necessary “scream” – just like a genuine electro-mechanic B3.

Plug and Play

The B4000+ features 128 factory-presets by default, which can be expanded by the user. With just a simple MIDI keyboard (with a MIDI 5-pin output) connected to the unit, along with the combination of drawbars, endless encoders and TFT display, the B4000+ will provide you with everything you need to start creating and playing your favorite organ sounds.

Just connect and enjoy!

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
