I've been going the hardware route lately. I'm now up to 2x UA-610s, 2x KT2As and 2x KT76s.
I ordered some upgrades for my drum mics. 1 Earthworks snare mic as an alternative to the top SM57 (keeping the bottom SM57 in place), and one D12 Kick drum mic as an alternative to the D112 bullet kick drum mic. I ordered an extra SM57 so that I can mic a guitar amp with an ordered Wilkinison Audio Fredman mic holder.
I'm considering building a guitar amp isolation box for my Line 6 Spider IV 75 and maybe picking up a Vox low wattage combo amp that could fit in the same isolation box as an alternative to the Line 6.
