Hello everyone,
I’m writing this post for all Kemper users who wish they could benefit from guitar profiles or guitar simulations. Like many of you, I really wanted the Kemper team to offer this feature, but I also understand their official stance against getting into guitar profiling. While it can be a bit frustrating, they did provide us with an Acoustic Simulation effect in the stomp slots.
Having previously tried to simulate other types of guitars using a graphic EQ placed before the amp profile, I came up with the idea of leveraging AI to explore this concept. I asked Google AI to help me build this kind of simulation. For this project, I used an Aria Pro II RS Series guitar, relying exclusively on its bridge humbucker (a humbucker with a rather moderate output level).
The AI suggested combining the following parameters:
- The INPUT menu
- The Acoustic Simulation in Stomp A
- The Graphic EQ in Stomp B
- The Compressor in Stomp C
For each requested simulation, it provided a complete set of parameters for all the effects mentioned above. Using my own knowledge of the guitars I wanted to emulate—focusing on specific personality traits (and I must admit, I haven't played them all, but I have a strong personal sense of how some of them should sound)—and through numerous iterations back and forth with the AI, I managed to get very close to what I felt was the authentic tone of these instruments.
I spent about 1 to 2 hours per model fine-tuning the effects to achieve this. Of course, I am not claiming that these settings can replace the actual physical guitars, nor that they are perfectly identical, but I am very satisfied with the results. Some models are outside my primary expertise, so those might be further away from the originals. While I targeted very specific historical models, the goal is clearly to simulate a style or type of guitar rather than an exact replica.
Hopefully, this collaborative approach can inspire the Kemper team.
To give you an idea of how the AI utilizes these effects:
- INPUT: Conditions the raw voltage and perceived inductance (the Clean Sens parameter manages the digital headroom).
- Acoustic Sim (Stomp A): Acts as a virtual coil and surface modeler (adjusting phase with Pickup, and mechanical impact with Bronze/Sparkle).
- Graphic EQ (Stomp B): The wood sculptor. It carves out the excess mud from the original pickup (avoiding the 250 Hz trap) and shapes the target resonance peaks.
- Compressor (Stomp C): The dynamic weaver using parallel compression. It shapes the note envelope to give it either elasticity or stiffness.
I will spare you the fine-tuning details for now (though I can provide more technical specifics if anyone is interested), but the AI seems to know exactly what to do with each parameter of every effect to bring out or tone down specific characteristics of the target guitar.
