I have had my KPA for a year or so now. Primarily a bedroom player. I have bought commercial profiles and only scratched the surface of the rig exchange. Finding tone can be a challenge. I tend to look for tones that match a particular song I may be working on at any given time, often researching the original gear that may have been used for the recording or live performance.
Guitar wise I have the basic ingredients, a Strat and a Les Paul, both with additional pickup switching options. Once I find a rig that suits I save it to the KPA in browse mode via rig manager and then copy it across to performance mode into the relevant performance slot(s) where I modify for effects/pedals if needed. I have also collected rigs for generic performance tones eg blues, jazz, pop, rock, metal (I can't shred).
The combination of factors that create a given tone can be very complex so I tend to search for a rig (via Rig Manager) that sounds very close without tweaking. I search for an amp tone I like then try various gain levels and mic types where these have been separately profiled.
Before I began this tone seeking process I backed up and then deleted all rigs in browse mode. Since then I have collected about 50 rigs in browse mode all used in various slots in performance mode. I can see this browse mode collection steadily growing and sometimes I find a new rig to replace an existing one where it more accurately nails the tone I want. All these browse mode rigs are very useable for me.
Before the KPA most of us might have owned a few guitar amps (not all at the same time) and have some favourite settings. Now we can have them all. Do you have a strategy for finding the tones you love?
