Born 2B Mild Posted May 30, 2009 Share Posted May 30, 2009 I do like my Shuttle, it's the best (and loudest) amp I've ever had, but there are times when I'd like to use three 8ohm cabs. If I replaced it for an amp head that could do 2ohms, what should it be? The lighter the better. Your suggestions are sought. Quote Link to comment Share on other sites More sharing options...

I haven't omce across anything comparable to the Shuttle that does 2ohms, has it got a preamp out so you can run a slave amp? Quote Link to comment Share on other sites More sharing options...
Kongo Posted May 30, 2009 Share Posted May 30, 2009 (edited) Only 2 ohm heads I know are older Peavey models. Other than that, why not buy a Stereo head and add another cab and run 4? Be balanced then. Edited May 30, 2009 by Kongo Quote Link to comment Share on other sites More sharing options...
EBS_freak Posted May 30, 2009 Share Posted May 30, 2009 EBS, SWR(at some point?), older Peavey are the ones the immediately spring to mind. multi cab option is cool! check my signature. Quote Link to comment Share on other sites More sharing options...

henry norton Posted May 30, 2009 Share Posted May 30, 2009 Alot of old valve heads can drive 2 ohms, although it's about as far from your shuttle size and weight wise as is possible to get.... Quote Link to comment Share on other sites More sharing options...

But remember, once you put it down your not carrying it anymore so +1 on this idea. Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted May 30, 2009 Share Posted May 30, 2009 One or two of the Glockenklang heads allow 3x8ohm loads but not 2ohms. However, when you are talking uber-lightweight then you are more restricted. If you are considering a change why not get a seperate preamp and a digi power section that will do 2 ohms?

As an example, my Hartke would run a pair of cabs at 175 watts each, and the single at 240 watts - a difference of less than 1.5 dB.

4-string-thing Posted May 30, 2009 Share Posted May 30, 2009 The old Acoustic Control Corporation heads would run at 2 ohms, I believe. I'm not sure if the new ones will, or if they will ever arrive in Britain! Quote Link to comment Share on other sites More sharing options...

chris_b Posted May 31, 2009 Share Posted May 31, 2009 Mesa Boogie, Thunderfunk, Ampeg, GK, SWR, Eden all have amps that go to 2 ohm. You can find the models which do! Quote Link to comment Share on other sites More sharing options...
haruki Posted May 31, 2009 Share Posted May 31, 2009 I know the old red fronted swr 350 goes down to 2 ohm - not the heaviest amp around either and quite compact too. Quote Link to comment Share on other sites More sharing options...

Also, its lower 'impedance', rather than resistance, means it's alternating current and varies with frequency. One of my vintage bass amps only has choice of 8 or 16.

I am in fact referring to Trace Elliot heads like mine, but this is by no means light and I'm not suggesting it as an option. Quote Link to comment Share on other sites More sharing options...

However, I was offering the suggestion of selling the Shuttle and getting either a rack or pedal pre-amp; otherwise you'd be better off going for a powered wedge (or expensive option like the Berg IP) or combo running the signal from a line-out from the Shuttle.
