That ^ will solve the "dangling" problem and is a lot cheaper than another mic! And BTW, you don't need to spend £100+ on an SM57? Prodipe make a very acceptable dynamic for 30 quid and there is a Behringer at half that price. 'Tis just rock n roll!

Not sure if the mixer/PA setup has been clarified but if there is no spare mic input on the PA you could use a small local mixer or even a low Z to 50k lifting transformer into the line input you presently use?

In my view, there's absolutely no point spending thousands on guitar, amp and pedals (it quickly adds up) if you then waste it on using a very cheap mic. No need to go mad, but avoid the cheap SM57 and SM58 lookalikes as they rarely achieve anything even close to the originals in sound and feedback rejection. I've bought a few to test out and wasn't impressed. Many are wired (badly) for unbalanced operation, when they could easily be wired for balanced.

The AKG P4 is a well-made compact sub-£50 instrument mic with a tight pickup pattern that sounds good on guitar amps. Spend a bit less and you loose a fair bit of fidelity, and often get either a very shrill or very bassy sound and a mic that's prone to feedback. It's far from the last word in amp mics, but I'd say it is the starting point in decent sounding ones that will give a decent rendition of your amp sound through the PA.

For the record, my room size comment wasn't entirely serious. I nearly always put something in front of an amp for exactly the reasons Sam mentions, rather have it and not need it and all that...

The Prodipe TT1 has been reviewed in SOS and Mr White found it quite decent I seem to recall. I bought one of the basic Behringers just to try it out and I confess I have only done a speech test but it seemed ok to me. Both mics are solidly made and are not trying to be SM57 copies.

Not sure you need massive feedback rejection that close to a loud amp?

It replaces the line feed from your amp going to the PA desk. So in practical terms, it would plug into the stagebox, and then appear on the corresponding input channel of the sound desk, and it would be used in exactly the same way as your previous direct line feed from the amp.... but it would probably sound better! :-)

Don't forget the amp sim route, either. I have seen three live bands in the last month and, oddly, all of their guitarists and bassists were using completely amp-free rigs, just a Helix or similar floor unit doing all the effects and amp sounds straight into the PA. The sounds were uniformly excellent but oddly hi-fi. You sort of miss hearing the direct, grungy sound from the amps. At the gig last weekend they even had a digital drumkit so the whole show was uncannily quiet but the sound quality was excellent. The loudest thing on the stage was the acoustic tambourine!

Depends on the amp. I heard a stunning guitar sound from a Tech 21 combo recently, using its line out straight to the PA. It's basically a Sansamp with a power amp and cabinet attached but it sounded exactly like a well miked combo. Forgotten the guitarist's name but a well-respected session/live player.

Really?

On my list of things which I don't miss this would sit somewhere between Smallpox and Margaret Thatcher.

Nonsense, there's something very special about feeling your flares flapping under the windy onslaught of a Marshall 4x12 at full tilt!

I'm sorry, you'll have to repeat that. I've got this ringing in my ears as a result of standing in front of a Marshall 4 x 12 going full tilt.
