This is a hardware sale, and more related to guitars, but I thought I'd mention it here.
There's a company called Decibel Eleven
https://decibel11.com that sells guitar effects & accessories. Two of their products were interesting to me: Switch Dr and Pedal Palette. Their website is having a clearance sale, and both of these are heavily discounted.
Switch Dr is loop switcher (effect send/return loop), with 4 loops. It does other functions including sending MIDI program changes, and CC values per preset. For someone with moderate effect setup, this rig may have some useful features for some. Lists $425, on sale for $139 (+10 shipping, US only)
Pedal Palette is also a loop switcher and has 4 loops. But rather than focusing on MIDI functions, the PP gives you the ability to switch orders of loops, switchable parallel paths, and preserve tails. I don't think all of the functions are storable in presets, but the basic functions are. It's got a pretty impressive feature set. Lists for $560, on sale for $159 (+10 shipping, US only)
