"noticed the GK. What happened to the traynor tube amp??"
I still have it, but don't take it to shows/venues that don't have a good FOH, much as I love how it sounds up to about half volume it honestly runs out of breath and gets way too "furry" for my taste when I push it a bit hard - and strangly so, it doesn't really make my 2 pup basses sound all that good either. However at larger venues I can run it at a relaxed volume with a single pup bass ( My Bach's, Lull and Greco) and just get a really nice tight, creamy vintage growl that I love. So I use the GK at smaller venues with no P.A. support, lots of headroom and good tone with all of my basses.
