Well, we'll find out in June! The Blues Cube may not be a tube amp, but this little bobble glows in a nifty green color. If I come out of it sounding like Clapton, we'll know the green rubbed off more than the color of my envy. ~m

I finally tried out the blues cube and its an impressive analog simulation of a big tweed amp, particularly if you ignore the overdrive channel and use it as a clean-to-crunch amp like one would use a tweed bassman or twin.... its missing the certain magic something like the way a good old tube amp will peel into musical feedback with a 335 and riving it too hard definitely reveals its not a prper tube power amp, but they got the preamp section really right. I might even buy one of these as an emergency backup or clean only amp to jam some jazz. I still wanna know what this little bubble of transistors masquerading as a 6V6 has going on? is there one in the cube already that you are swapping out? ,aybe it refines the voicing and behavior of the amp to be closer to a tweed fender?

Great notes Jim. I really dig the clean channel. Adding the Tone Capsule results in a loss of the stock, crystalline clean. It warms the sounds slightly. The difference is notable when doing and A/B, but you're ear is much more well attuned. I'm a novice when it comes to amps.
