Bigjas Posted April 19, 2012 Share Posted April 19, 2012 Hi there I currently have a Marshall MB4410 combo and a Hiwatt 100 valve head. I woould like to be able to switch between the 2 amps during a set, but only use one cab (the Marshall cab). Would it hurt either of the 2 amps if i used a splitter box so that both both amps are connected to the one amp at the same time? I would only use one amp at a time using an A/B footswitch so i could switch between heads without turning amps on/off or pulling leads. It just saves having to lug around two cabs but I am worried it could harm either of the amps if they are both switched on and connected to the same cab. Both amps are 4ohms and so is the cab. Thanks Jas Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted April 19, 2012 Share Posted April 19, 2012 Pretty bad plan all round. Valve amp needs a load, so especially bad involving one.Not really sure why you' want to use stuff other than a Hiwatt if you have one anyway. Quote Link to comment Share on other sites More sharing options...

chris_b Posted April 19, 2012 Share Posted April 19, 2012 You can share a cab but you can't share the speakers in a cab. I played with a guitarist who had a 410 rewired so that the left pair of speakers were powered by 1 amp and the right pair powered by a different amp. 2 separate cabs would be a better idea for you.

Bigjas Posted April 19, 2012 Author Share Posted April 19, 2012 Thanks for your replies I love the Hiwatt head, really nice tone, just not loud enough for some of the songs we play (we have a very loud drummer that tells me to f off when I say he is too loud) its 100w and just gets swallowed up on some songs where the drummer gets carried away. My idea was to have the Hiwatt for most of the set and just switch to the Marshall on some songs. I'll just have take 2 rigs with me cos I don't want to stop using the hiwatt.

Bigjas Posted April 19, 2012 Author Share Posted April 19, 2012 Just had a thought, the Hiwatt has a slave channel. Could I link that to the PA to give me some more headroom? Jas Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted April 19, 2012 Share Posted April 19, 2012 What cab are you suing? Right cab will sort the volume issue. Quote Link to comment Share on other sites More sharing options...

[/quote] Of course, but the OP said he would be switching between amps, not using them concurrently. The OP really does need 2 separate cabs. On the other hand I would probably go right off topic and just run the Hiwatt through a Barefaced Super12T. Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted April 19, 2012 Share Posted April 19, 2012 Would avoid the T, and go Super 15. Which is exactly what I do. Quote Link to comment Share on other sites More sharing options...
Dad3353 Posted April 19, 2012 Share Posted April 19, 2012 It's a very loud drummer who can drown out a DR103 with the right cab. I would suggest trying out a few efficient cabs, and leaving the combo at home once you've found the right one. Once you're sorted, you won't be able to hear the drummer, whatever he's mouthing. He'll be begging you to turn down; just ignore him. Play on. To answer the question directly: no, you can't share the cab between the amps. Magic smoke will ensue.

bertbass Posted April 19, 2012 Share Posted April 19, 2012 +1 to that. You could D.I. the bass into the P.A. Quote Link to comment Share on other sites More sharing options...
Musky Posted April 20, 2012 Share Posted April 20, 2012 There are cab switchers about, but they're not cheap. As has been said, the need to keep a load on valve amps' output means this is never going to be a cheap option. http://www.customaudioelectronics.com/products?view=product&prod_id=prod7 Quote Link to comment Share on other sites More sharing options...
Bigjas Posted April 20, 2012 Author Share Posted April 20, 2012 Thanks for the advice guys, you have just prevented a 1974 Hiwatt going up in smoke............ Looks like a decent cab is required, any ideas on which configuration? 4 x 10 or 2 x 10 or 1 x 15 ? Is anyone using a similar amp, if so what cabs are you using? Once again, thanks, this forum is great for idiots like me............... Jas Quote Link to comment Share on other sites More sharing options...

[/quote] Well, you are right, the cab makes a big difference. Last night I had band practice, so I took the Hiwatt head and the 2 cabs that came with it. They are old PA cabs, each of them has a Goodmans Audiom 12-P 50 watt speaker. I didn't think they would be all that good as they are dated 1976 and only 50 watts each (the Marshall 4x10 is rated at 450w), how wrong was I!!!! When i ran this head through the Marshall 4x10 the volume was just over three quarters and it was struggling. Through the goodmans speakers, the volume is on less than half, and the sound is unbelievable. So much tone and clarity. What a rig I now have. I am considering making a new cabinet to house the 2 speakers. Thanks for all your advice, I am so chuffed, can't wait to gig my new rig on Saturday.

They are probably really middly like a guitar speaker which gives you the volume and clarity. Seeing if the cabs you have are stuff if sealed and line if ported might squeeze even more from them, but making a new box that sounds the same might require some analysis of what makes the boxes you have good.

fretmeister Posted April 27, 2012 Share Posted April 27, 2012 The Headbone is supposed to be a good bit of kit and not too expensive. Certainly cheaper than getting a couple of Motherlode attenuators and running them at nil output then using the emulated outs to a power amp and then into the cab.
