Blumes® is an all-analog tri-mode soft clipping bass overdrive that carries the torch of the classic screamer circuit but has a voice all its own. While embodying most of the characteristics and features of our beloved Plumes® Small Signal Shredder, this modified circuit has double the gain and a deeper bass response to retain all the low end. It utilizes internal bipolar power, which gives you more dynamics and all the headroom you could ever desire. The end result is a three-dimensional tone with added clarity that really pushes a nice tube amp over the edge.
