EarthQuaker Devices, On Hold, Overdrive

From the post

30th October 2014 - Put on hold pending investigation :o)

Info about the original:

The Earthquaker Devices Monarch Overdrive is an FET, all discrete dirt machine that will get you some truly vintage and organic overdrive. The Monarch Overdrive is based on a certain UK hard rock amp's input stage that shares the same color as the Monarch's brilliant design. This pedal provides high gains that are largely compression free, for a truly organic and natural sounding overdrive tone that really gets the sound of an overdriven vintage amp. The treble and bass controls are essentially frequency boosters, and not simply the run-of-the-mill roll off filters found in most all overdrive pedals. These controls are centered in the preamp section and really provide some depth to the tone and overdrive characteristics of the pedal. This provides you with a solid bottom end and clear and crisp top ends for rich harmonic overtones that ooze vintage overdrive. This is the overdrive pedal to get for larger-than life fat chord work and a thick and significant bottom end. The Earthquaker Devices Monarch Overdrive can also be used with higher voltages to yield more headroom, a fatter and more focused tone and a wider gain range.

The Earthquaker Devices Monarch Overdrive is one thick and meaty overdrive. Taking the best elements of a vintage UK rock amp, this pedal delivers some balls-out tone. As with other Earthquaker Devices, you have some real control over the tonal characteristics of this overdrive, by boosting frequencies rather than rolling them off. The Monarch Overdrive gives you some real vintage overdrive, but also some real tonal variety when you call for it.

Features: Gain: Controls the amount of overdrive Level: Controls level of output Treble: Boosts highs Bass: Boosts lows Power: Regulated 9-18v power supply with negative 2.1 mm center barrel
