I have a 70’s lotus bass, it is single split pick up. I know that there were some neck thru models made in the motsumoku factory where they made aria models and others. I see the aria SB-1000 on eBay and stores for 1200.00. The wood on those arias is identical to my lotus but the horns are different on mine and mine has a split pick up instead of the soap bar. I haven’t found another lotus like mine and I’m just wondering if anyone has and if anyone knows what It’s worth. It has a great tone and sustain and the vintage cool factor is great with the original thumb rest. Another detail is the truss adjustment is at the bottom of the neck at the body. Thanks for any info!
