I've been poking around trying to figure out my transistor strategy for the Carcass Fuzz that USPS swears is "currently in transit to the destination."
While I learn a valuable lesson about patience, I thought I'd start a thread to collect some resources on Carcosa transistors.
I few places have mentioned that transistors with high hfe (600+) resulted in unpleasant squealing, and that the sweet spot seemed to be ones with gain around 500 - 550.
As far as transistor choice, a few of the posts above mentioned that 2n5089s were a little too hot.
A few alternatives mentioned:
1) What transistors have people tried in this? What gain ranges have seemed to work best?
2) If I have a handful of transistors with varying gain, is there a recommended order I should put them in? (e.g., lowest to highest gain? vice versa?)
I'm going to socket everything, but wanted to tap into collective wisdom ahead of time.

Booster, OD, Fuzz, Distortion - DOD Carcosa Fuzz - Verified
DOD Carcosa Fuzz - Verified. PedalPCB released a schematic of DOD Carcosa Fuzz over at FSB Couldn't resist to make a layout, will build this tomorrow. Cheers.

A few alternatives mentioned:
- 2N5088
- BC109C
- BC549C (lower gain; lower noise; not enough distortion)
