Ibanez TS-808 Mod+
Keeley Mod


The TS808 has great tone to start with. This pedal is now the culmination of many ideas and modifications that Robert had developed over the years. Every component added is of the highest quality. There are metal film resistors in the circuit to improve the signal to noise ratio many guitarists desire. Film capacitors are used in the tone section to provide the smoothest mid-range and high frequency. The overall bass response has been improved as well. This pedal has been modified to have the More/Less Mod. This allows you to have less distortion in the lower settings of the Drive control and more distortion and saturation in the higher setting of the control. All of the stock TS9/TS808 settings are possible throughout the midrange of the control. Plus, none of the singing sweet midrange tone is gone!

What you get with the Ibanez TS-808 Mod Plus!

1. Better bass response along with true mid range and high frequency transparency
2. Wider range on your tone control
3. The More/Less mod! The modded Tube Screamer can get cleaner and more distorted than stock. 4. You get the 808 output mod which gives you more output volume
5. All of these mods make the TS-808 Mod Plus the ultimate version of the famous Tube Screamer you can have!

All Controls set at 1+/- O’clock. This is a nice starting position with good biting drive and gain.
  • Set the Level to 3 O’clock, Drive at 9 O’clock, and Tone anywhere that sounds good to you. This is a good clean boost and great for distorting the input of a tube amp.
  • Set the Level to 4 O’clock with the Drive off. This is a SUPER clean boost with the More/Less mod.
  • Set Drive to 4 O’clock and the Level to 12 O’clock. This is a super sustain setting. Great for lead work that is very saturated yet retains the essence of your guitar!
