Aria ATO-1 Tube Overdrive

 Schematic is avaiable HERE.

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?

  1. Wow, the CMOS gain stages are arranged like a Bluesbreaker, kind of. Haven't seen that before! Gotta try this one for sure.

  2. Tag 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!
