Not your Tubr Screamer derivate as the name would suggest. Instead, we have a four stage CMOS overdrive with an op amp preamp, a TS style Treble control and a gyrator for the Bass control. Could it be a sleeper?

Wow, the CMOS gain stages are arranged like a Bluesbreaker, kind of. Haven't seen that before! Gotta try this one for sure.
ReplyDeleteTag it! I didn't find any adjustments that needed to be made. Sounds decent, I was getting a good amount of sustain. All the pots act in the way you expect - the lows rolled off very quickly below 75%ish however I was using a 10kB as I didn't have a 10kW on hand - should I have tried a different taper or value first? Seems to give a fair bit of tone flexibility you can get from this given the range of both the high and low pots. Thanks!
ReplyDeleteThis caught my interest so I decided to build it up, and this is excellent! The bass could probably benefit from the wonky 10k W taper pot, but b taper works okay. The only other substitution I made was swapping that 15pf ceramic cap for 22pf because I couldn't find 15 for the life of me. I can't imagine it makes a huge difference to the final sound. Much better than a tube screamer.
