I/O for Macbook 12 (USB 2 or 3 I assume)

ToneControl

Any ideas on a reasonable but cheap I/O

Must be a proper DI, that has proper impedance for guitar inputs, and XLR mic input

What is the actual budget as reasonable but cheap is quite vague.

My tip is avoid Focusrite Scarlett 2i2, the headroom is not high enough for DI guitars.  Even the 2i4 with pad cuts it fine but just about has enough headroom for most applications, I've never clipped it but have been close (IIRC I was getting peaks at -3 with pad engaged and gain on zero).  I have 2i4 for mobile and 18i20, but to be honest I only record DIs at home and have found better results using a Palmer Active DI box.  For mic preamps the Scarletts are fine.

Budget, yeah....I have an Alesis iO2 that seems pretty good and they retail at £70 or less, doubt there is anything 1/2 decent new, below that. Do NOT ffs get a really cheap single pre amp AI..

I don't know how the iO2 hangs for DI input headroom but I COULD shift my lazy A  and squirt my Levell oscillator at it!

Never heard a bad word about the Steinberg UR22. £100.

My NI KA6 is superb in almost every way but about another nifty.

I bought a presonus Audio USB

It's great, except it "just doesn't work" on the Mac ;-):

Works fine on the PC though

I've ordered a Komplete Audio 6

it has one of the best latency scores for any USB IO:
