When you record the dry guitar signal through a DI, the DI ups the level with a preamp. The re-amp box will lower the level again and match the impedance so it's more like a signal coming from a guitar.
Do you have direct monitoring coming out of your monitors while you're recording? Maybe you're hearing the DI guitar and the amp sim, then when you play back it's just the amp sim. If your interface has a playback and input mix knob, try turning it to playback only.
It's quite limited - it's part of the Apple package of apps included with all their Macs. I don't think you can use any 3rd party VSTs. Probably does what you want, though.
You can configure the 13 inch with 16GB (for a hefty £160 more than the 8GB equivalent!), but the 13 inch MacBook Pros come with noticeably lower powered CPUs than the 15 inchers. Do you need 16GB? I have 16GB, but hardly ever go over 4GB used. Remember that Apple kindly solder all RAM in so you...
Sounds pretty badass, Greg. Bit gainier than usual for you? I preferred the 1959, just slightly - the picked notes sounded a bit more defined (if that even means anything!).
That's exactly what I'm after. I wouldn't know what particular sound I want - I just want to be able to play a couple of notes from the current chord and add some wah to make me sound better than I am.
