ElectroniX Submarine Bass Guitar Preamp Pedal. I'm really not certain what version this Sub is but it was one of the very last that Os built. The date inside shows July '09.
This is THE pedal that most say they will NEVER sell but I really need to thin out a portion of my bass gear. I'm not using pedals much any longer so...
Here is a link that I found that kinda explains what this pedal does. Review: Electronix Submarine
The pedal would be 10/10 if it weren't for the tiny chip in the paint by the output jack. It does have industrial grade velcro on the back also.
$150 shipped USPS ground in the CONUS only.
