Just a quick hello as I am new to using Blackstar amps. Got the HT1R head and HT112 cab. Playing a Gibson ES 335 with EH Soul food overdrive. Loving the amp, both clean and OD are very warm sounding. Still dialing in the pedal but it is sounding great. Looking at replacing Blackstar speaker with a Celestion Greenback. Anybody done this? Also, any good delay pedals which work well with this setup?
