yes, it does happen occasionally. always works the second time.
i just lost an hour playing my gibson semi through the plexi 100 1970 into a stereo cab with F60 (fractal gb) and F132 (tv mix 2)
treb drive 6, norm drive 4, bass 3, mid 8, treb 8, pres 8, master 10, sag 5, speaker low freq at 95hz (reduce input trim if it's a bit over the top...i have medium output pickups and my input set to stereo, not left only)
so creamy and dynamic!! an absolute pleasure to work the pickup selector and volume and tone controls on the guitar...every position...every variation...all amazing...
