BYOC Overdrive 2 w/Mosfet mod - $125.00
PayPal, shipped USPS con/US.
Assembled and modded by me.
Internal switch to put the boost before or after the drive.
Socketed so you can switch out all the Mosfet stuff for non-Mosfet stuff, and bass mod parts for non-bass mod parts (spare parts included for both).
Along with the bass and Mosfet mods, sockets are also in place to experiment with the Feedback cap, Tantalum caps, Input cap, and Boost gain.
I can mod it back to bass specs if you like (easy to do with the sockets). Currently set up as:
Op amp: Burr Brown
clipping - Silicon/none/Mosfet
boost - Mosfet
boost order - drive > boost
In this configuration the drive can be run at 18v, which makes it louder with more headroom, and less breakup at lower volumes. For more breakup, operate at 9v volts. (18v operation not possible with Mosfet op amp, it'll blow up).
