It’s different alright , cleaner , deeper, having a separate gain and volume makes it a lot more versatile. I’ve played it out doors with no problem. You just have that extra bit of headroom. But I do miss the LB-30. I use an old Carslbro 50w guitar valve head at home just because it sounds so good, plenty of low end for small gigs and the overdrive channel gives the best dirty bass sound I’ve ever heard.
BTW the CTM100 is 19kg which isn’t bad at all, well worth a punt. Also check out handbox 120w amp from Poland
