A single triode stage circuit typical for guitar preamps is captured in this plugin. The model engine is based on a system of non-linear ODEs. Some smart calculation techniques are used to reduce the computational load.
This effect could be used to apply mild tube overdrive to add some presence to your tracks, or you could chain a couple of instances together for a full-blown high-gain overdrive. You may want to throw in some EQ as well to better shape the signal and use a poweramp/speaker simulater afterwards.
The model has 3 core controls to configure the circuit:
- 3 different triode models: 12AX7, 12AU7, 12AT7.
- 3 different plate voltages: 150v, 250v, 350v.
- 3 different cathode capacitors: 0.47uF, 1uF, 22uF.
What do I think about it ? Well, I spent some time with AXP SoftAmp 3OD. At first, I ran Kontakt 5 (Christmas present ... bought to myself ;d ), selected some nice guitar, turned on AXP SoftAMP 3OD and ... loved it. While I'm not a guitarist, I can still hear ;) if some plugin makes the things sound "nice" (in a good way) :) This freebie sounds so ... gentle, subtle or maybe I should say pro :)
I really like when some freebie excels my expectations. AXP SoftAmp 3OD is a great example.
