Thanks to you guys esp. CharlieC and caeman I have picked up a BVAP. It was £37 off eBay, fully functional.
I've read both threads and am putting it to use at church as a preamp into the only bass monitoring we have a powered full range PA cab. This is tilted back and was just plugged...
New member, returning to bass from the wilderness...
Here is my "new to me" C4 LTD, all stock. Great tone, neck and action, just a re-string and a little setup work required to make it perfect...
