Its normally tuned as bollinger tuning, so you can’t really tune your 2nd valve without having it done for you at a shop. But its around halfway between a G and a Gb
I ordered a stock bass Edwards. I use this tuning so I ordered the parts for a tuning slide and had a really good tech cut it down for me. Now I have a Gb and a quarter tone G. This way, if I ever sell it, I have both tuning options.
