Just got a brand new MG30GFX combo 30 watt with 10" speaker, the overdrive sounds very digital and muffled. No presence or bite to it. I even tried hooking it to a real Celestion 12" speaker in my DSL40CR and that didn't help. I have a little MG15DFX combo 15watt with 8" speaker and it absolutely destroys the new MG30GFX in tone. Sad how we seem to have went forward with technology and the nice foot pedal with presets but way backwards in tone. I wish I knew how to add an effects loop to my MG15DFX, all I'm looking for is a way to change the delay/reverb while I play with a small combo amp. Does anyone know some older solid state combos that sound good with footswitchable delay or an effects loop?
