Maxon Super Metal. Made in Japan in 1984. It features two rare, glossy JRC 4558D op-amps and two TEXAS INSTRUMENTS MC1458P op-amps! There are some imperfections in the paint and scratches on the metal parts, but it works without any problems. The footswitch also functions properly. How about it as a collector's item or for parts? When the gain is reduced, it can produce a sound similar to a TS-9. Although the name is "Super Metal," it doesn't distort that much even at maximum gain. *If it doesn't sell within a few days, I will remove the listing. Please understand. Body only. Will be carefully packed and shipped. (The following is a quote) Although it's called Super Metal, I don't think it's that deep of a distortion by modern standards. However, it allows for a wide range of sound creation with its 3-band EQ, and the gain ranges from distortion to crunch. Surprisingly, I think it can also create sounds from blues rock with a mid-boost to alternative and grunge. In that sense, I personally feel that it's similar to the Marshall Shredmaster. Looking at the circuit board, it has two glossy JRC4558Ds and two Texas Instruments MC1458Ps, making for a rather luxurious parts configuration. ＿＿＿＿＿＿＿ maxon od9 od820 ibanez TS9 ts808 tube screamer super metal FUZZ distortron BIG MUFF RAT BOSS DS-1 DS-2 distortion op-amp opamp Maxon Ibanez Type...Electric Guitar Manufacturer...Ibanez
