Question about Positive Grid Spark guitar amplifier

Spark 40 is the older one, Spark 2 is the new version of it (since about October/November 2024). Slebe mass and range of use, with new features such as looper, long-term battery (excl. but the possibility is created) optional footswitch (without guarantee, but I don't think it works with the Spark 40) and possibly a little more than the 40W (I'm not sure anymore).
