This Ibanez Keeley Modified TS-9 Tube Screamer is in good condition. It is in fine working order with some signs of wear.
The stock TS9 has a great tone to start with, but this pedal is now the culmination of many ideas and modifications. 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 midrange and high frequency components to your tone while increasing the bass response of the pedal.
The choice of capacitors for the unique Tone Cap mod is to increase the lowend tone of your guitar without the slightest bit of muddiness or dullness to your tone. It is not a bass boost. The integrated circuit is the Texas Instruments RC4558P. This chip was chosen because it provides the best sound quality available. 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 settings are possible throughout the midrange of the control. Plus, none of the singing sweet midrange tone is gone!
