Hi!! Thanks!! Any chance for the Cornestone Gladio SC?? The schematic is up on Pedalpcb.Cheers!!
ReplyDeleteThis one looks interesting! Anything on EQD's Blumes Bass Driver yet?
ReplyDeleteIs this for bass?
ReplyDeleteI think it's emulating solid state pre equipped Music Man guitar amps. I saw Joe Strummer playing one in a clip the other day. I may be mistaken but I think The Band are playing them in The Last Waltz. Correct me someone if I'm wrong.
DeleteThanks Tom
DeleteI really like the Blackstone as a bass drive personally.
DeleteThe Blumes is for bass (and totally unrelated to this circuit). It's basically a modern Tubescreamer for bass.
DeletePedalpcb has boards for the Blumes; the build doc isn't uploaded yet, though, and I've not seen the schematic elsewhere online. My guess is that the only real difference between the Blumes & Plumes is that the input cap has been raised from 33n to something like 100n or 220n, and maybe the feedback caps upped from 56p to 470p.
DeleteIn the meantime, though, if you want a bass-friendly Tubescreamer, look at the Black Arts Witchburner. That thing is pretty gnarly. Run it at 18V to get the same headroom as the Blumes.

DeleteKinda verified!
ReplyDeleteBoth the Mids and Bass controls were working in reverse. I checked the schematic and your layout matches it, so perhaps a typo in the original schematic?
I switched the necessary connections and now it works as you'd expect. I used a TC1044SCPA for the charge pump and 2 x MC1458s (as recommended in the original write-up by EAE) for the op-amps.
Works great as a clean pedal platform, but really shines in medium-to-high gain situations with it's buzzy, gnarly, harsh distortion sound.
