Some interesting points here. I currently have three amp set ups (I need to sell some stuff!), and each set up has its merits. First up is a JCM900 head and a 4x12 cab. Big, heavy, inconvenient, yet pretty iconic. Interestingly, even when I played the Barras, I still had it set to run at half wattage. Other than recording, I never use it at full wattage. Second is an ENGL Thunder 50 and a Mesa Boogie 1x12. This is ace, and is the sound that I had throughout the first Curators album and gigs. However, it's not hugely versatile, and I do like the reverb options of the JCM900. However, now that I'm an old married man I bought an Orange Tiny Terror combo plus extension cab, and it's that set up that I have been using since. It's loud as fuck, fits in the boot and I can't see when it would not be suitable. Even without the cab, I really like how it sounds. I don't entirely agree with the statements above about it not really mattering what you play through for gigs. In my experience, the exact opposite is true. A shit amp will sound shit, regardless of what you run into it. I remember playing a festival where you had to use house amps and I just couldn't get the sound I wanted. If your guitar sound is really important to you, try to use your own gear if possible, or at least make sure that the house gear is good (e.g. The Moorings). I am terminally allergic to modelling amps for live sound. Every single time I've used or heard one, it has sounded poor. Fine for demoing, but that's as far as it goes for me. Basically, being a gear snob is lame, but you do need decent gear to sound good. Anyone want to buy a head and cab? ;-)
