This is a tuned-up MOD of the Ibanez Tube Screamer TS-9 JRC4558, the champion of overdrive pedals, which SRV loved. It's been upgraded by swapping in a 4558 and further tuning! Current models are long sellers, but there's a sound that only this early model can produce. The reason SRV favored it is here. Currently, there are no operational issues. Unlike some models, it switches reliably every time you step on it. I'm selling it because I have too much gear. Please understand that this is a vintage used item before purchasing. Please refrain from purchasing if you are overly concerned about details or seek perfection. I aim for smooth transactions. Body only. Please prepare batteries. It will be shipped in a reused cardboard box with cushioning material. Please note that it may be changed to Yu-Yu Mercari delivery. Thank you.
