GHOST TEMPORARILY RESEARCH (GTR ELECTRONICS / GHOST EFFECTS) Ghost Effects, a British company, is highly regarded for its reproductions of British fuzz pedals, alongside D*A*M, PIGDOG, Castledine, and Jerms. This brand produces replicas that have been praised, with the owner of "Macaris," a famous London Denmark Street shop deeply connected to the history of the Tone Bender, saying, "the sound is better than the original mk1." This is the "HARMONIC GENERATOR," a reproduction model of the BUZZAROUND by Ghost Effects. It features three NKT214 transistors. The BUZZAROUND and DIZZY TONE have three controls that interact with each other, often resulting in a high volume when trying to achieve your desired sound. However, this model has an optional master volume, allowing you to adjust the volume after you've dialed in your preferred tone. DC power is also available as an optional addition, allowing for use with an adapter or power supply in addition to battery power, making it very easy to use (※Please be sure to use a DC9V center-negative power supply). Serial number 2, with the original box. TC Gakki was selling a used one for 77,000 yen.
