Thornybank Posted January 7, 2010 Share Posted January 7, 2010 I took an Ampeg SVT-115 Classic cab in p/x. Sounded awful and wimpish. My tech checked to see if it had a pathetic driver. No - cast frame (Chinese) Eminence. Snipped the spade connectors and hardwired the speaker - big improvement in mid (any at all, now). Hmmm... Connection to the crossover board is a fiddly crimp on with spring contacts onto two rectangle bar thingmies all in a nylon junciton thing. Snip. Solder. NOW IT IS A CAB!!!!! Sounds amazing - 100X improvement. Wow! Ampeg - shame for that fiddly crap tone sucking nonsense. And they retail @ £549!?!?!?? Worth it after the mod, though. A great cab trying to get out.....

bigjohn Posted January 7, 2010 Share Posted January 7, 2010 (edited) I'm really not sure about the chinese ampeg stuff... they had their problems with the PCBs being botched out there and have now moved their whole production line? I've spent £100s getting ampeg stuff brought up to spec in parts and labour (and that's all been "US" built)... at least that worked when I bought it though Although - now you've got it fixed it'll be fine. As my man who fixes this stuff says (despite being a lover of quality) it's decent stuff, it's just built sh*t. But then he's not got a good word to say about anything other than Mullard and Powersoft. Oh, early Sansui (for hifi) Leeds built Celestion, good pioneer, yamaha and some other stuff I've not even heard of are ok too... amcron, uk built carlsbro etc. Peavey stuff doesn't break but sounds sh*t... At least the ampeg stuff gets a mention and he'll fix it rather than you having to sling yer hook. If yer lucky. Ampeg stuff comes into it's own when it's been tweaked a bit.

Thornybank Posted January 8, 2010 Author Share Posted January 8, 2010 If there was a list of 'waht to do' to get the music out of the gear, then here could be a standard shop prep routine that undoes all the jive. What amazes me is that a cab that is 'worth' £549 when it is sorted out is hiding inside something that sounds like s*** that they charge £549 for. That's £449 for a logo?

Really quite something inside, big and full of point to point stuff. Quote Link to comment Share on other sites More sharing options...

In almost every case. Because it does, friend. I have many, many dozens of heads and cabs and have heard ithat dif many, many times. This isn't snake oil or attitude: Solder involves the full circumference of each strand and locks the mechanical contact in place. In a non-vibrating, oxygen free environment you could maybe trust a friction contact -if he crimping put more than one or two cables strands into contact with the spade in the first place. And as soon as there is oxidation or less-than-perfect contact, how much signal is getting through? Ever needed to clean an input jack? Same thing.

Obviously the clamps aren't ideal especially in a cab where there going to eventually work their way loose or become tarnished and cause problems, whereas directly soldering will bypass all these problems but the method of connecting it isn't going to have a massive effect on the sound!
