This is an Ovaltone buffer and junction box. Ovaltone's buffer is very brilliant and natural. I think it's characterized by its ability to bring out picking nuances. It can be used for both guitar and bass, and I really liked it. However, I'm selling it because I've come to prefer the Klon Centaur buffer. The functional feature of this buffer is, of course, the tonal change via the toggle switches. Especially the top two toggle switches. The left one is a bright switch, and the right one allows you to select from three different tones. It's very creative and fun to be able to change the tone while considering the characteristics of the equipment. This is a discontinued product and is very rare. How about it? #buffer - Brand: Ovaltone - Model Name: PRIME GEAR - Type: Buffer - Features: Variable input impedance - Terminals: Connection/Disconnection - Switch: Hardwire bypass Thank you for viewing.
