The whole system is designed to benefit buyers. The more buyers that buy stuff the more ebay makes in selling fees from the seller. So screw the seller, they want more buyers!
I'm totally against this. When you fill out the description on ebay say "contact me for other payment options" I just sold a Pedulla on ebay and it really sucks to have all that cash held until mr slow poke finally leaves positive feedback. I called Paypal and tore them a new one. It's...
Lighter gauge strings will help a little, and just play, play, play! You'll need to practice lots to build up the kind of stamina Harris has. Not everyone can do what he does, and for that matter, as long as he's done it! he's a monster.
My calipers tell me it's a .125 B and .105 E, I ordered some medium gauge Rotos for it. On my four string basses I normally use Funkmasters which have a 0.95 E.
I'll probably try a set of Roto's on it and see how they work, it's been a long time since I've had a fretted 6er. My fretless 6er I don't worry about changeing strings on :D
I just got a ESP D6 6 string bass, which sounds nice, the SIT strings that came on it sound pretty good but they're really tight! I usually do a lot of bending but these suckers are like iron rods. I use standard 440 tuning, and normally use Rotosound stainless.
