Hi Paul, your equipment sounds really nice. I am playing through a pre fender SWR Workingmans 300 with a pre fender Workingmans 4x10 bottom. I am looking for something to round out the bottom, I was thinking of a Big Ben or a Son of Bertha, problem is none of the online stores will ship heavy stuff like that here. There is a muaic store here called Bounty Music, they only have a Son of Bertha, not real sure what I am gonna do yet, but I am keeping track of your custom build bass. It really sounds like a beautiful bass. I can't wait to see it. Are you in a band, or do you do recording or both? I am in a kinda blues band called Blind Willy. We have fun, play a gig here and there, I just put some new strings on my Spoiler, some GHS Brite Flats, I usually use GHS Progressives, but I wanted to try a flat wound to see how it works. So far so good. Take care, Ken.
