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.

Ifs its dual power amps like a Little Giant, then one will be running at 8 and one at 4, with the three cabs, so would be unblalanced.

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?

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.

Yeah. But remember, once you put it down your not carrying it anymore so +1 on this idea.

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?

It wouldn't make any difference in the real world - the cab that's on the channel by itself might be 1-2 dB louder, which is about the smallest change you'd notice, even if you have good ears.

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.

i've not seen many that can do 2 ohms apart from ampeg, it takes some serious iron to go that low

any reason why you want to use 3 cabs? wouldn't it be wiser to use 1 or 2 bigger or more effiecent ones?

The DB750 goes to 2 ohm and is stable there.....

I've used two 100w Marshall heads and an Ampeg and they've all gone down to 2 ohms, but having said that I haven't looked that closely at any other vintage amps - I just assumed they all did the same! On that note, I wonder how easy it would be to modify an output stage so it could drive a lower resistance?

You'd need a whole new output transformer, and some remodelling as it would likely be bigger. 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.

Amps with two channels can have independent level controls as well. 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.

Mmmm. I believe the Shuttle can work as a pre-amp. What sort of wonga is needed to add such a power amp? I've got a feeling I'm not going to like the answer!

Edited to say a big [i]thanks [/i]to all other suggestions, which I have found most useful, whilst I way up the options. I'm not sure how soon I might want to change things now, but I intend to go on researching it.

I believe Ped and Dood have both researched and purchased 'relatively' cheap compact power-amps. 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.

How about a Genz Neopak?
