The Thomas Guldmann Octa-switch MK3 is a versatile effects switcher designed to manage up to eight effects pedals. Each pedal connects to one of the true-bypass loops, allowing seamless integration of both vintage and modern gear.
Musically, this unit enables you to easily switch between different combinations of effects for various songs, thanks to its intuitive DIP Bank system. Each bank can be programmed to activate multiple effects simultaneously, with blue LEDs indicating which loops are engaged. Additionally, the Octa-switch MK3 features a Bypass switch for an unaffected amp tone, along with two external switching jacks for channel control on amplifiers. Power options include dual 9V batteries or a regulated power supply.
