Ultimate Drive opamp mod

Just popped a Burr Brown opamp in my Joyo Ultimate drive, It’s had a JRC chip in it for ages which helped reduce the noise level, the new opamp however has improved the tone and the range of the tone control seems to have improved, I can now go past 12 o’clock without things too brittle.

The next plan is to try the alpha mod and see how that affects the range of the controls, from what I’ve read it keeps them in ‘mojo’ territory and avoids any of the extreme settings possible on an unmodified pedal.  This should be fun…

Remember if you want a pedal moded, contact me through my website and I’ll see what I can do
