I've used a Mesa boogie Walkabout head and various Mesa boogie cabs for ages and one of the things I noticed when playing at home for practice and at a gig last night was that it doesn't give a good full sound at low volumes. The gig was background jazz so low volume needed as people needed to be able to chat. But doing that with my walkabout head and powerhouse 1x15 meant there wasn't much bottom end coming through. Something that is never a problem at my regular pub/venue gigs at proper volumes. My main rig for bigger gigs is an F1-x driving a QSC PLX 2402 and usually I turn the power amp controls to max on the QSC and adjust the pre-amp to suit and that does everything at any volume and is clean, full range and clear of hiss even when very low but that was just overkill for this small gig. At soundcheck I did try turning the master volume up high on the Mesa and leaving the input gain low but that just introduced hiss even before my bass was plugged in. Any tips I could try?
