The team's opinion: You probably already know this, but Carl Martin is a brand that we appreciate. Indeed, our Danish friends have accustomed us to offer original effects pedals, of good quality and at a very competitive price. The Hot Drive is no exception to the rule. This is a product combining 2 circuits: An overdrive and a boost, which can be used independently of each other. At the same time, the sound then approaches a distortion, offering a relatively thick grain and very present harmonics. The strong point of this pedal is the transparency of the boost. Indeed, although the drive channel is close to a JCM800, the boost is perfectly transparent and only increases the sound of your amp without distorting it. Maximum gain, the sound is reminiscent of the sound of Slash on the Gun's first album. With a guitar mounted in double it then becomes easy to play in a Hard-Rock / Glam register. Metal fans will unfortunately have to go their way. Small precision, the pedal also has a "clean" output for those who want to use only the clean boost function. An endearing, affordable and now rare effect pedal because it hasn't been manufactured for several years. Please note that the power supply is integrated into the pedal as a plug! Strange choice but important to clarify.
