The ski jumps I have seen are all within the pocket section. In that region the strings have almost same leverage over the neck whether there is a shim or not. But lifting the neck off the pocket at the rear gives that leverage somewhere to go.

It calls for some imagination. In engineering it's known as a "free body potato". It frees your mind to examine forces at play. Here it's the neck section in the pocket. Screws pull it down. The pivot points push back as described. The free body has forces in balance. You are then free to examine the internal bending forces that are generated as a result of the external forces in balance.

The standard village hall width is 2 x boom freq wavelength.

The forces induce bending moment in the neck. As soon as the holding down force of the screws is apparent it is resisted at the pocket end and the shim or the neck would be in motion. A beam force diagram for you:

Less bending but still the other end bears all the load at the very end beyond the screws and nothing in between is supported. Someone posted a photo of an end shimmed Wal neck pocket the last time ski jumping came up. It was very clear that most of the pocket never made contact with the neck.

That's because you don't do physics. Turn it all on its head. How does a neck get skijumped? Answer. Because force is applied over small distances over a long time, and timber warps under constant bending input.

Byline. The 80's never die.

Die Hard

If end shims didn't cause ski jumps there would be no ski jumps. It's basic physics and materials science. Wood creeps under constant load. An end shim puts a constant bending force into the pocket length of the neck. Both sets of screws are yanking down and the support is the very end of the neck where it leaves the body, and the shim. You can see the wear at the leaving end contacting the pocket on removed vintage necks. Whether the neck ski jumps is down to the particular quality of the neck timber. That is why it happens to some and not all. Full length shim = no problem. No escape from that maths.

Players often complain the raising guts the lows. That is not what is happening. They are getting a way bigger earful of tone and the same amount of lows. Guitar players are the worst for that.

Way back when... two JBL 15 based PA cabs had 50w a side up them. Vocals and a little bit of doof from the kick plus one guitar mic'd while the other ran an overkill stage rig. Bass was the trusty Trace 250 and 1518. BL had to lean on Mr Overkill to play ball and let the vocals be the loudest thing as they both sang. That way he didn't drown me out, which was the actual problem as the PA kept up with me and drummer just fine. BL was a crafty old dude. He mic'sd his weenie combo into a monster out front.

I wouldn't trust a 500w RMS rating on a 210 unless it was a very expensive one. 0 0 0 0 Is how to arrange two 210 cabs. You hear it far better and so does the audience when it's playing to the room. 200w through those Eden cabs should make plenty of noise. Good luck with your search for some well priced used stuff.

Once you get over that it's all fun. Play along with the TV adverts at home. Most have a readily catchonable bass riff. If you don't get it first time you get another crack in 12 minutes.

The USD is high at the moment. Not sure how that translates in the used US market. Used gear is traditionally super cheap there.

How much would break the bank? What you need is something that can keep up with well hit drums. Then you are covered for any gig that comes along. A couple of old 210 cabs and 250w amp is plenty for that.

Tight basterd that I am I couldn't bear the thought of the hasty but stellar recomposition going unrewarded if I was the original writer. Maybe it's his only significant income but I'd like to think I'd still send a bit to the TG guy.

From the little I know about caribou I'd say they find croquet hoops entirely disintesting fodder and / or your fence scary. Otherwise it would have to be some seriously serious fence to stop one from venturing to the manicured side if he had a mind to. As for the cat manicuring itself on a bass pickup, that's one messed up cat not content to make war on bass via the cabinet.

That efen cat!

I'd be pretty chuffed too, to be picked up from my house and taken to gigs where I got paid. I'd probably even load my own 210 into the van, while bandmates half my age watched, and leave the bookings to them, happy as Larry!!

U bass for the win. About the same stress level as playing air bass to a sequencer.

Exists already, half rack! Nobody much uses it these days though. My parametric EQ is a half rack unit. It's almost as old as me.

They are waterproof on circuit boards much as pure H²O is an insulator.

If there's a bass amp it's running on mains power. You can always unplug it and pop your double plug in its place.

I am not seeing anywhere it isn't a stone's throw from mains power. Learn how to wrap a cable so it comes out straight instead of a birds nest.
