PRS SE Hollowbody II Piezo Tone Report:
Had a chance to sit down with my new arrival today, and stretch her legs somewhat. Here's what occurred:
1) First plugged the MIX jack into my HeadRush Gigboard & FRFR108 powered speaker. Immediately discovered that my usual CLEAN rig setting was more distorted at higher guitar volumes. Solution: Adjust the Boost Volume and amp model gain and volume slightly downwards. After this, it was also noticed that my ACOU acoustic rigs also were much too bright and distorted. Again, an adjustment of Boost volume and Amp gain, volume and EQ was required. At this juncture, the HBII's tone was cleaner, clearer and less harsh.
2) It was decided that it was time to try the HBII through my Clarett audio interface using the MIX jack. The INST jack was plugged into the HeadRush. It seems that the piezo control puts out appreciable signal. The Clarett's optimum input setting was just under 3 o'clock, based on a 7 to 5 o'clock range. Any more caused signal clipping. It was also discovered that the piezo knob works best just about 9, and the magnetic pickups knob set about 7-½ to 8. The full benefits of the acoustic properties are heard at these levels.
3) Personal opinion: Utilizing a 2nd instrument cable for the piezo is almost a requirement if one desires to hear the piezo acoustic properties in its correct form. The MIX jack will work for both a mix of piezo and magnetic pickups, though the blended pickups won't represent both piezo and magnetic pickups as separate amplification possibilities. The cleanest and clearest acoustic tone is obtained with 2 instrument cables plugged into both jacks.
4) All in all, IMHO, the PRS SE HBII Piezo shines when you can hear the magnetic pickups cleanly with the piezo. The piezo adds a touch of crispness and clarity above the magnetic pickups that is unobtainable when there is no piezo. Also, the SE HBII Piezo produces a beautiful lead tone reminiscent of Larry Carlton's work on Fingerprints and Fire Wire. Although it's necessary to credit the HeadRush's capability for imitating the classic 'D'-style amp tone using the Black Duo Norm amp model, that just on-the-verge of amp break-up produces a violin-like lead tone...smooth and slightly overdriven. It was also possible to dial in an acoustic amp tone by utilizing an AC Hi Boost model & an acoustic cab IR, and dialing back on the brightness and gain. This amp model produced the acoustic tones written about previously. The brightness and gain previously were much too harsh and clipped. Dialing down the gain and treble improved the acoustic tone appreciably.
5) Conclusion: The PRS SE Hollowbody II Piezo is both a workhorse and versatile guitar that can produce enjoyable tones with the correct amplification and settings. Although it took a bit of sweat equity and effort to dial in the desired tone, once the settings were saved to the HeadRush, practicing with the guitar, the HeadRush and audio interface was now a joy. It really doesn't take a lot of figuring at all to appreciate both the guitar and HeadRush. The guesswork is taken care of when you sit down with your gear and set about making some adjustments here and there. And now the adjustment aspect of my work is complete. Now to just practice and make sense of what my fingers are trying to say. I'm sure you'll experience something similar when you take some time to adjust your amp settings, and if possible, connect the MIX jack to a dedicated audio interface or PA.
