DB33 is a virtual B3 like tonewheel organ instrument that even has a rotary leslie like cabinet. The instrument's interface has a page for the organ and a page for the cabinet. Let's look at the organ page first. On the left side we have got the rotary tonewheels. Tonewheel organs are based on a system of spinning saw-like metal wheels, magnetic pickups translate their motion into sound and their condition actually affects the overall tone of the organ, hence some of the choices that we have here. We have got Dirty, Used, New and then over here we have Sym1 and Sym2, which refer to a synthesized triangle wave and a synthesized square wave. Let's take a listen to all of these using just the factory default sound. (Music playing.) To the right of the Tonehweels we have the Scanner Vibrato section. This has three Chorus and three Vibrato settings and the On/Off switch which turns it on and off. So, let's turn it on and have a listen to some of these. (Music playing.) Next, we have the Draw bars. The Draw bars on the organ are used to control the combination of various harmonics generated by the Tonewheel mechanism. The low harmonics are to the left and the higher harmonics are to the right. I'm going to play a chord and pull some of these Draw bars in and out. (Music playing.) So you can use these to really sculpt your sound. Next, we have the Key Click.
The Key Click gives you control over the clicking sound made by striking a key, let's check this out. (Music playing.) I am going to switch this over to the sound. To the right we have Percussion section and this enables you to add a burst of additional harmonics, when each note is played. I'm going to turn it on and try this out. (Music playing.) To the right of the Percussion section we have the Master Level. This sets the overall output level. Let's move down to this really cool control, the Rotary Speed switch. This controls the speed of the rotation of the Rotary speaker. We can go from Slow to Fast and there is Brake in the middle and that will stop it if you leave it there or just momentarily slow the Rotary speaker before moving it to the Fast or Slow setting. Super cool! Let's check it out in real time. (Music playing.) Now let's switch over the Cabinet page. The Cabinet page provides controls for the rotating speaker cabinet and the organ's Tube Pre-Amp, both ultimately affect the overall tone in a big way.
The Organ Level sets the volume of the Organ before it enters the Pre-Amp. Turn this down if you are hearing too much distortion. You can also use an Expression Pedal on this control to emulate a volume paddle. (Music playing.) An awesome feature of this instrument is that you can actually use the Cabinet part as an effect, just as a plug-in effect as opposed to an instrument. You can actually route a guitar or a vocal track or whatever through this Rotary Cabinet effect, without even using the organ. Use the External Level, right here to set the volume for the incoming signal.
The Tube Pre-Amp has three knobs that we can use to control the sound. First we have the Character. If we turn it to the Left, the lows are cut and the mids and highs are emphasized. If we turn it to the Right, the lows are boosted and the highs are cut to give it a warm sound. (Music playing.) The Drive knob controls the gain and the Pre-Amp and you can go from a clean to a distorted sound. (Music playing.) The High Cut is a treble cut and you can use this together with the Character and the Drive control to create some unique sounds. (Music playing.) A real Rotary Cabinet has two speakers in it. One called the Drum and the other the Horn. They are mic'd separately. So here in DB33 we have control over the mix between the two mics in the Drum and Horn knob. (Music playing.) As you can hear the Horn is a little more trebly and the Drum is a little more bassy. The Spread knob sets the stereo spread between the two mics from 90 degrees to 180 degrees apart. (Music playing.) The Speed Control section affects the Rotating Speaker Cabinet's speed of rotation and the time it takes to change between speed modes. Here we have the rotation Speed Control again, so that when we test these out, we can hear what it actually sounds like using the controller. (Music playing.) We switch this over to the Brake the Acceleration and Deceleration knob changes up the time between the Speed Modes. So it depends on how fast we get to the Slow or the Fast Rate when we hit the Brake.
Finally, the Master controls the Output Level. One last thing I want to mention are the Presets. There is a ton of presets up here and what's really cool about them is that they indicate the Draw bar positions for each sound. So now you know what all the Buttons, Knobs, Switches and Draw bars do on the DB33. Use this knowledge to create any organ sound you want and enjoy the amazing amount of control that you have over the DB33's parameters.
