Horrible noise when removing amp lead from guitar..
Downunderwonder replied to a topic in Amps and Cabs
And if you turn down the input gain first before yanking the amp end out won't even get a pop. -
Low frequencies are omnidirectional. When they hit walls they come back without losing much energy, so much so that we credit it with full energy. That return wave can be in phase well enough to reinforce the original wave when the source is close, or a half wavelength distant from the wall. But at 1/4 wavelength distance the return wave is fully out of phase and you get a cancellation. The original wave headed out from the speaker towards the wall and away from the wall. Having travelled 1/4 wavelength both ways, before rejoining the original, the reflection is half a wavelength delayed ie a cancellation. A bass cabinet in a corner gets all the bass energy focused into 1/2 the space of same cab set along a wall. Go outside and lose half your bass power to the catering area out the back. That's pretty dire! If you look up Allison Effect it will tell you more than you want to know.

'A' boom is tricky because it's right in the breadbox at 110hz but worth a crack. You probably have walls 6m apart, 2 wavelengths.

It's aluminum, which is heavy enough in that quantity.

Pull down 130hz in the PA to tame a boomy C.

Can "c0ck" please be removed from the swear filter?

"Feck, the feckin fecker's feckin fecked!". Shows it is in fact highly feckin versatile enough to cover exclamation adjective noun adverb and verb in the one sentence. -
Lucky! A ceiling about that height makes an acoustic guitar bloom on every C chord. They will look right at the bass player to blame.

What makes a song hard or easier to learn?

Bassy guitars. -

If you are handy with a soldering iron it's pretty easy to make a power cable shorter. Snip out an over lay ie opposing short and long tails, and then trim overall length to suit. Don't forget your heat shrink. Doing it overlayed makes for only one piece of heat shrink required and a nice neat job.

I'd love a tonic jacket for gigs, if I could find one budgie style in the op shop before some other fashionista snaffles it.

Save me from myself - possible 1x10 cab build

As opposed to posts joining walls across the cabinet style bracing, BFM style. -

Borrowed mangled English for 'wall' 'joist'. ie thing what stiffens your wall, innit guv! -
Facebook taken over - update re FB Marketplace
Downunderwonder replied to Steve Browning's topic in General Discussion
From what we discussed earlier I think they start by posting as a friend messaging you about some b.s that requires a code. They quickly pose as you to FB locked out or wanting to do admin or sommat, and you are silly enough to give it to them. That's the only way I can see how it could be done short of an actual hack. How they fool you that it's your friend messaging you on some other platform I have no idea. -
I set mine so they WILL clank if I want. 98% of the time they won't, and it's nice seeing heads turn when they do.

Bass ‘choking’ in the upper register
Downunderwonder replied to Bass Wielder's topic in Repairs and Technical
If not 'ski jump' deformation the easy fix would be a shim under the bridge. -

There's that word again. Nut or bridge end? -
Someone who knows how to sew shouldn't be complaining about being given helpful advice after they complain about not being able to buy shirts with stars preinstalled in their high street, or about having the borax poked at them.
-
As a nurse you must surely have a good handle on sewing!

I hope they had a preamp for you to plug into.

The SWR RED HEAD, anyone still using them ?
Downunderwonder replied to funkgod's topic in General Discussion
I saw one in the wild once. The band was setting up as we were passing through on our way to our gig. So never got to hear it. -
They make these things called scissors. You apply them to the kind of fabric you would like your stars to be, in the size and shape you would like them to be, with a little extra around each edge that you fold under. That folded edge is the edge of your star. Then you apply this oldfangled technology called "needle and thread" to your stars just back from that edge and hey presto you have a shirt with stars on it.

One time my vintage Trace 15 was plugged in with a BigBaby. The BB was inaudible so I am picking it gives up a fair mess of sensitivity to vintage stuff in order to go crazy loud with lots of watts. I imagine a super compact version of a BB isn't going to punch its way out of a wet paper bag without at least 200w up it. Every 3dB of sensitivity deficit you start with requires that you double the power to make it up. That's well and good when 1000w amps are cheap as chips. Not so much with 50 going on 100w. JBL E140 based cab is what you want. Mic that puppy into the PA and you will be envy of bassists around the world.

Over the other side of the pond there is a thread on a 110 coffeehouse cab made from a cheap prefab 10" subwoofer box. It just happened to have the exact right porting for the s2010 which is close enough to the 2510 that others threw those in instead and Bob came through. Others copied the box with a shelf port instead. I am pretty sure it wasn't as generously sized as Bill's optimal tune but big enough to not suffocate. -
Lots of very cheap Trace amps in the classifieds at the moment. The trouble with some modern lightweight super high performance stuff is it actually needs a bit of wallop behind it to make it go. Try with you old iron before you buy.
