So far, I am a bit disappointed because the 150 lacks bottom end punch and the volume is whimpy compared to my tube amp. It really sucks bass wise. The celestion in it does not do the job. I am tempted if I keep it, to stick a vintage 30 and bypass all "special design" by either fixing it or screwing it up all together, LOL.
I guess for a practice amp in a tiny room it would be okay for some people, but engineers, you have the right idea but your sound guy is clueless. You need the "punch" to feel the sound. You want to feel the mp3 at the same level of a real band playing, otherwise why would you call it a gig amp, it is not!!!!!!!! Just put a name like "Closet practice amp" or something along those lines.
Then I thought, build a "real cabinet" with 13 ply baltic birch to see if you can get the whimpy sound away from it and get into a more acceptable sound. Who knows...maybe you need about 300 watts to get the sound level up to acceptance. Then I thought, why these engineers do not sell a sub-woofer on the side to go with it so you can hear a killer heavy metal sound or an out plug to connect to a PA system to enhance it without microphones. The headphone plug sound is worst, too whimpy when connected to other speakers like a 2x12 or 4x12.
I am very disappointed and may just return it to the store. Also, I want a unit with backing tracks with a huge database with backing tracks for guitar players so you can mute the lead guitar of the backing track and you become the lead.
You are close to what some of us customers need I guess with the bluetooth and the app, but you can do way better on volume and bass sound.
Help or it goes back to the store. I like the multipurpose thing but man, give me some volume and punch! Not boominess, just punch so my bones rattle!
