Great little amp
"The 20rt is an excellent two-channel amp for practice and low volume rehearsal. Both channels just feel good to play. It is actually a bit more fun to play at practice volume than the 35rt is, which we also own. The clean channel breaks up just a bit, but very nicely, at practice volume, which I like a lot. I bought this for my daughter to use for for pit-orchestra rehearsals at school and low-volume at home. She required either two channels, or a boost pedal, for what she's doing. I refuse to spend weeks/months trying out boost pedals.....been there, done that. So this small two channel solution does the job very, very, very well. The line-in feature - to play along with music is an essential part of practice IMO so I'm thrilled with that. Also the headphone out for someone who is still learning certain things and sometimes does not want anyone listening just yet....
The thing is, I'm impressed enough with this little guy as a practice amp, that I'm ordering another one for myself. Two good channels, whose tone not only sounds good but feels good, good dirty tone, good clean tone w/ a bit of breakup, small, lightweight, just plug in and go. As a busy dad, playing is all about the ability to sit down for say 15 minutes at a time, so access is critical, not futzing with knobs to get a good tone.
Buy this little amp, you'll really enjoy it. It can rock pretty hard, produce a very respectable volume level, and the amount of gain this thing can deliver is way more than you'll probably ever need. I've owned a lot of tube based stuff, and still have much of it, and I'm happy to ditch the complications of that gear for a while and just focus on playing. This thing frees you up to just play....
Update 3/19/19: My daughter has an upcoming performance requiring both electric and acoustic-electric parts, amplified. We assumed she'd just take my Fishman loudbox for the Yamaha acoustic, and then the cr20rt/MIM Strat, which is pretty minimal....BUT that changed when I tried the Yamaha straight into the clean channel of the 20rt. The verdict - All she needs to bring for both guitars is the Orange(!). The Yamaha straight into the clean channel is very, VERY good, not sterile at all, transparent, nice touch, nice dynamics. Awesome.....Secret's out!!."
Perfect little amp!
"This amp sounds good at low power, so it’s perfect for the bedroom player. Turn it up, and it’s a capable stage amp too! It’s clean circuit is crystal clear, or you can turn it metal with the push of a button. Tuner flashes slower as you get closer to the pitch, which is nice."
