This is a SUNN THE TWIN amplifier. It's famous for being used by Futoshi Abe of THEE MICHELLE GUN ELEPHANT, and it remains a popular model both in Japan and abroad. It's said to be the same inside as a Fender TWIN, and it excels at delivering Fender's signature crystal-clear clean tones, as well as a surprisingly good drive sound on channel 2. Robben Ford praised it, saying, "You can do anything with this one amp." It's perfectly capable for both live performances and recording. It's a bit heavy at around 30kg, but the included casters help to reduce the burden. There are some minor scratches from use, but nothing too noticeable. There is some lifting of the front panel and some rust on the metal parts. One of the metal rings at the input jack for channel 2 is missing, but it works without any problems. There is no crackling or unusual noise, and it sounds clean. A footswitch is also included. The reverb also works beautifully. It has been discontinued for a long time, and well-maintained examples are rare. Enjoy the authentic sound that you can't get from today's digital equipment. This valuable amplifier was designed by Paul Rivera to handle both crystal-clear clean tones and drive sounds.
