Joyo R-30 Tidal Wave Bass Preamp

It's basically a Sansamp but cheaper.

You are met with very little resistance when moving the dials. You'd better take a picture of your settings before throwing this in the pedalboard carrying bag, because the dials are VERY easily repositioned.

Would've liked them to be a bit stiffer, like my Darkglass and TC Electronic pedals, but I can't really complain for the price.

great tone that easily adjusted. feels resilient to damage and compact.
