Lots of hype on this one early on and lots of delays in production (no doubt COVID slowed things down), but it's now readily available, and man -- this thing is pretty awesome for a practice amp for the price. $239USD shipped. Hard to believe. This is less than the price of most boutique guitar pedals.
