To respond to a couple questions.
I got the iM2306 Pelican case from B&H photo supply. It came shipped for $66.
Regarding the P-1. I spoke to Peter who hooked me up with a P-1 and 500HR rack. After listening to audio samples found through
https://www.frontendaudio.com/Articles.asp?ID=171
and reading about bassists using mostly the Gold, I asked Peter which would be the best for my situation.
He basically said, if you're ONLY going to use the pre for bass, then get the Gold. BUT, if you're going to use it for other stuff as well, then get the P-1.
I'm lovin' the P-1. To me, the P-1, in comparison to the Gold, from the audio samples sounds like it has both a bit of upper-mid and high spank to it along with a great low mid fullness and punch. The Gold seems to have more mid-mid punch and a tad warmer sounding.
That's what I heard!
Here's a pic from a session I did a year and a half ago using the REDDI for the first time.
