Death by Audio Soundwave Breakdown 2

Last week for Fuzz Friday I posted the early version of the Soundwave Breakdown from Death by Audio. Here's the newer version of DBA's Soundwave Breakdown with 6 transistors and another external control. On earlier examples of this revision the Sensitivity pot is an internal trimmer, but the newest version seems to have moved it externally. Speaking of trimmers, this one still has the Volume control as a trimmer (50k) and the other trimmer (5k) biases Q6. Originals are in a 1590BB, but I've laid it out to fit in a 1590B with board mounted pots. Drilling template can be found here and the schematic can be found here.
