Dubnium Drive/DBA Interstellar Overdriver
« on: August 13, 2019, 11:18:34 AM »
Had a request for one of these from a band mate so was happy to oblige thanks to finding a board from m-Kresol/Felix, great work!

After reading the various circuit analysis posts I was expecting trouble with it in regards to the weird reversed transistor set up but it ended up being fine.

For me it sounds great, kind of an overdrive with a fuzzy edge to it, pretty gnarly but definitely usable into a clean amp. Didnít get any of the gating some build reports mentioned using all 2N5089s however I tried swapping Q1 out for a 2N5088 and thought it sounded better, almost richer so left it in.

Etched with NaOH/caustic as per usual, would have liked it to be cleaner in places but my mate was happy so job done!

very cool build and I really dig the artwork. Simple, but effective.

Good to hear that my pcb creations are being used from time to time. I really appreciate it

Nice build :) i am gonna have to give m-kresol's board a try ... :/ i tried building the deluxe version of it and a supersonic fuzz gun both of them are super gated and wont even let sound pass unless my guitar volume is at max :/
