Rare JDM Maxon TB09 True Tube Booster Overdrive.
2023 production , in near mint condition with original box & instruction leaflet. In 100% perfect working order.
Also has Japanese supplied multi-input voltage powersupply. Works better on our in-house Vitoos 500ma output p/s IMO

A truly versatile Boost & Overdrive pedal that really does both things well. It all depends where you put the Drive Control .
Massive voltage pump that ups the internal voltage to 30 volts means the tube is not just there for decoration!

Fully description from Maxon:

World’s smallest tube-based Booster Overdrive in a 9-series enclosure. (Jan. 2008 Maxon research)

Employs subminiature tube with US Military specification.

Provides comfortable and powerful tube sound which is very difficult to create with a digital processing simulator.

9V from AC adaptor is bumped up to 30V by the internal regulator and provided to tube circuit and overdrive circuit. Stable high quality sound is constantly available with increased dynamic headroom.

Unintentional signal Distortion is greatly reduced.

TBS (True Bypass Switching) using 4PDT mechanical switch lets your instrument's signal pass through a non-electronic bypass line when the effect is disengaged, feeding your amplifier with direct,unaltered signal from your instrument.

Employs tube heater inrush current control circuit to extend tube’s life.

AC adaptor AC2009 can be used worldwide from 100VAC to 240VAC by auto voltage sensing.

Main countries' safety standard approved. Useful for worldwide touring musicians.
