At least for me, restarting after 30 years due to mid-life crisis, I found the initial enthusiasm blunted by the reality of the need to practice and learn.
But Drop D and Gain made some fun noise quite easily. I couldn’t do an Em Pent scale for a couple of weeks, but I could bash around with 1 or 2 fingers in Drop D to reinvigorate the enthusiasm.
I also found that Delay helped me with Scale practice. Too boring for me otherwise. And a drum machine/Looper. I may have studied Mathematics a long time ago, but found it very hard to count to 4 in time for 8 bars let alone 12.
YMMV
