I'm running my Eden i90 Chorus at 12v and an Eden Glowplug at 18v and both seem perfectly happy. Would be interesting to see what voltage the internal voltage regulators are. Remember you need reverse polarity connectors though. I'm actually using a Caline Scuru truly isolated power supply run off an 18v dewalt battery as well!
I play bass, ibanez fretless (with piezo) and acoustic bass and currently run the following effects
Palmer Acoustic DI (> pickup compensation > Notch >) fx loop send >
POG2 >
Glowplug(as a soft limiter/warmer) >
I90 Chorus >
volume pedal >
Boss Acoustic DI (for body resonance, ambience (a delay reverb) and notch filter)>
Fx Return > Palmer DI EQ and speaker emulator
The Palmer acoustic DI is just the same as the bass one internally (they sent me the schematics when I enquired about signal levels!) with without the fuzz/dist and with switchable mag/piezo compensation and a 3 position speaker emulator.
Thinking of getting a CaliforniWah or MXR Filter too to add some filtering up front.
