Two of these:
Carslbro Marlin PA 150
I have one on each of the headphone channels from my laptop. I am lucky enough to be able to practice at decent volumes most of the time so they're handy for the backing music. I just turn down the "Low" on the laptop channels and play over the recorded basslines.
I also have a TR606 (hidden under Soul Fingers, a book about The Duck, sorry) plugged into one of them. I can run mics and if needed, I can add the pair of wedges (Celestion CR 102) to the home built (by another BC member) pair of red speakers.
They could be applied to a small PA situation with eight channels between the pair if I could find anyone to accompany me on my own personal journey into music.
In the meantime, I continue to cry into my pillow before I go to sleep to dream of lost opportunities with the band back in Dublin many years ago. If only I had been on the dole. Heeheehee. In truth, have no real regrets. My job stood me well and left me comfortable enough to enjoy my hobby today.
