DC-9 Overdrive is a circuit modeled overdrive plug-in that emulates the famous Ibanez® TS9 Tube Screamer. The DSP algorithms in DC-9 take into account the entire schematic, using the latest modeling techniques. This gives you an authentic analog sound that matches the character of the physical circuit. DC-9 is an Audio Unit Extension (AUv3) that works inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect. The controls expand when touched so they can be easily seen while tweaking. DC-9 brings the distinctive warm overdrive crunch to your favorite iOS DAW. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more. DC-9 gets its name from the Diode Clipper circuit used to create the distortion. Accurate modeling of the clipper by circuit simulation gives DC-9 an edge over the common distortion plug- in. The effect was carefully tuned using A/B comparisons to the original stop box. Blamsoft brings their experience creating top notch plug-ins for the desktop to iOS. The same algorithm is found in the popular Rack Extension for Propellerhead Reason. You get a desktop quality algorithm at an iOS friendly price. Tap Developer Website for sound examples. Note: Second screenshot shows the effect of touching a control.

DC's advantage is in-app purchases (none vs 1) and iOS requirement (12.0 vs 17.0). On review sentiment, update cadence, ads and device support there is nothing between them.
