@Zampa, what’s your budget? I was about to recommend a Phil Jones Double Four but it seems that may be over budget at around £300 used.
If you can pick up a used Line 6 Studio 110 it may be exactly what you’re looking for and for not all that much money either. 4 band EQ, DI out, some basic amp modelling, one knob compressor, headphone output. I’ve had one for years and it’s served me very well.
