From the vendor

Project overview:

Glory Drive DLX has all the features of the Glory Drive but includes an entirely switchable extra gain stage mod and an external Hi-cut switch.

The hi-cut tonal effect improves tone shaping and feedback control, but the fact that it is hard to flip on the original Glory Drive can be a drawback. This pedal’s sounds are sweet and can add a lot to your effects rig, and the addition of the external remote switch gives you even more live performance options.

Introduction

Don’t you love when something keeps getting better and better? This is definitively the case with the classic Marshall Bluesbreaker. It all started when JHS pedals made a version addressing some of the original circuit volume issues by adding a JFET output buffer. They also added a high-cut switch to make the pedal more suitable for Strats and single coils.

Glory Drive DLX features all those improvements and includes an entirely switchable extra gain stage mod and an external Hi-cut switch. This is the final step of a series of enhancements that transformed a good pedal into an exemplary one: a low/mid gain drive that works equally well with single coils and humbuckers for everything from blues, country, and classic rock, and it’s almost impossible not to get a great tone out of it. With a barely open gain knob, your sound will be pretty close to what you used from your amp. From there, you dial in the gain till you get the number of overtones you desire but still open. The pedal produces more treble the further you crank the gain. That’s where the high-cut toggle comes in handy, depending on your setup.

This latest version of an already well-thought pedal is now at the pinnacle of circuit evolution. No wonder why so many people like it!
