About this listing
Mint condition, never gigged, Robert Keeley TS9 MOD plus, now discontinued. Swapped Components:​The standard op-amp chip (TA75558 or Toshiba) replaced with a Texas Instruments RC4558P chip installed in an 8-pin DIP socket. ​The two output stage resistors (470 ohm and 10k ohm) swapped out for 100 ohm and 10k ohm resistors to match vintage TS808 output specifications. ​Key signal path capacitors changed from stock electrolytic/tantalum parts to high-tolerance metal film capacitors.​The RC filter capacitor in the gain stage upgraded from 0.047uF to 0.1uF.​Resistors adjusted in the feedback loop to increase maximum drive capability while allowing the pedal to turn down cleaner.​The clipping section diodes swapped or modified for asymmetrical clipping. ​The dim stock red LED replaced with a high-brightness blue LED.​Sound Benefits:​A warmer, smoother high end that eliminates the harsh upper-mid range glare.​Restored low end and tighter bass response without making the tone muddy or flubby.​Increased clarity, overall dynamic range, and transparency when playing lower-gain settings. ​A wider range on the drive knob, offering cleaner low-end cleanup and more gain on tap at the max setting.​A noticeably lower background noise floor and reduced idle hiss.Key chip, resistors, caps replaced with superior components to the stock version resulting in
