Thank you very much for viewing. This is a listing for a used Keeley Franken Screamer TS9. A valuable Franken TS-9! This is a modified early model Keeley, with significantly improved sound quality and usability. I purchased it as a rare collector's item and have kept it in storage. This pedal is based on Keeley's most famous modification technology, MOD Plus. This means that with lower settings, you get less distortion, and with higher settings, you get more distortion and sound saturation. Furthermore, while obtaining the above-mentioned controls, this unit does not lose the sweet mid-range that sings well. The unique Tone Cap Mode brings out the deep bass of your guitar without making the sound muffled. The heart of the IC uses the RC4558P from Texas Instruments, which currently delivers the best performance. I am listing it this time because I have other equipment I want to buy. The accessories are all shown in the photos. *The serial number on the back has been processed in the image. Please ask any questions you may have before purchasing. *This product is also sold on other sites, and may be sold out. No claims and no returns. *We hope for a smooth transaction.
