I figure someone here might have gone through this already. Just picked up a used but really clean 1st Gen Blackstar HT5R 1x12 combo. Perfect for bedroom volume playing. I'm actually surprised at how good it sounds. The only thing I don't love is the stock Blackbird 12" that came with it. Can anyone recommend a replacement 12" that would sound better? Maybe with better mids and highs. I know it's matter of preference but I think as SG enthusiasts, we all have a similar idea of good tone.
