You need to gig it loud! It's actually a 40 watt amp, it can do it. And then the stock speaker loosens up. It's not all that bad but you don't get a £70 OEM speaker in a £140 amp. Also try turning the hidden noise gate off. Press Bypass(FX off) then Press&hold Edit-1 button and turn Edit-2 knob to zero, release. That gate is a waste of milk, it ruins touch sensitivity by removing small signals Also turn the power limiter on the back to near-maximum to "open up" the sound of the amp, otherwise it sounds congested. Use the MV. Very few of the pots are pots, they're effectively rotary switches telling the computer chip what to do, as does that starved plate valve, it does not amplify.
