※ First come, first served on other platforms!! It's old, but it works perfectly, no problems at all, and the footswitch lights up with a "Fight! Ippatsu!!" (One Shot!) display!! LOL You can mess with the op-amp, or leave it as is. If you're considering an expensive TS, you should try this first. This is a cheat effector loved by my favorite unpretentious guitarist, Satoshi Henmi! ^_^b "Product Introduction" It's not very well known, but it's a legendary machine for those in the know!! In a word, it's a super versatile effector that combines the best of the beloved vintage TS and vintage RAT, covering clean, crunch, overdrive, and distortion. It's the No. 1 effector in my personal ranking, making me want to buy multiple TS808, 9, 10, 5 and Maxon DS-F1!! LOL Basically, start with the MID at MAX (I almost always have it at MAX!! LOL) and adjust to your liking around 2 o'clock, BASS at 12 o'clock to 2:30 (around 2 o'clock for single coils), and TREBLE between 12 o'clock and MAX, and you'll get a fantastic, magical sound that makes you think, "This is good enough, I don't need a vintage TS or RAT!!" Also, as a booster, it's so amazing that you don't need a TS - it's the strongest effector developed by Nisshin Onpa Seisakusho in Matsumoto City, Nagano Prefecture, the holy land of boosters, for those in the know! ^_^b Please copy and paste the following to check out the sound!!
