It is a shame Gibson sat on the Kramer brand for so long. They could be coming out with all sorts of new models. What they have is basically what was available in 1985.
Guitar amps are very mid-focused, so they wind up sounding a little like an AM radio. But thing is, for improvising, you just need a handful of chords played at a steady tempo- you don't need a drum machine.
I always opt for something that makes it play better than historical accuracy, anyway. Leo did get a lot of things wrong, partly because he wasn't a musician, but mostly because he would use whatever was cheaper or whatever he got a deal on.
Hearing rhythms through your guitar rig blows...it really does. Also if you get your distortion from the preamp of your amp, put the looper in the effects loop, otherwise it will distort the audio in a bad way. If you are going to use it in-line, make it the last pedal on your board.
I had one of these, but I didn't use the onboard rhythms, and I didn't need the ability to store loops. If that is something you could use, go for it. You could also find a used express on Reverb (there are 31 currently, about $50US) or somewhere else.
I like to support small shops too, but honestly, the amount of time it takes for them to get small parts (they have to order enough at one time to get a discount ordering) keeps me looking for small parts online where I can get things in a day or 2, often with free shipping. Would I pay 3x as...
Yeah, a simple looper (you might look for a battery powered option) is the right tool for this job. The less I have to set up, and not limiting yourself to a certain place (like in front of a computer) will make it seamless and more likely to practice.
the tiny Ditto has 5 minutes. But for improvising, most chord progressions are usually less than 30 seconds, really. So you don't have to play a round of chords more than once.
