haha hey watts isnt even proportionate to loudness! To put things into perspective, my yamaha ga10 7 watter on volume 5 is around the same as volume 3 on the smarvo. 40 watts is only slightly louder but sounds much better because of the 12" speaker cone, more power for an especially nice bass as well as overall sound..
i have it at home (HDB), no problems at volumes 3-5 actually. The distortion gain knob is super sensitive, just move up 1 unit like from gain 1 to 2 and there's a big jump in volume. 1.5-2 is the max my hdb flat can take thank you very much =D
the distortion channel sounds good to me actually, since i use it as an overdrive solely, can obtain a relatively fat and interesting singing tones for melodic rock by eqing the presence and shape on neck humbucker and reducing tone knob on guitar for an airy open feeling.. for punk rock/full out distortion i think it just isnt saturated enough.. cant get the right-in-ur-face blast
on clean, there's where it shines. very crisp and balanced sound - very full. i use digital efx for distortion on this channel thru my korg 1500.. however i'm mostly just guitar to amp now becoz the korg tends to deaden the clean somehow..
overall realli great value for money ^^ great clean tone for a 40 watter solid state amp in this price range, all this just in my honest opinion of course =)
